Robots and people are joining forces

Continuously increasing sales figures. Next powerful momentum through artificial intelligence.

You can rely on robots – and not only for precision welding, bending and cutting of pipes or for transporting and depositing pipes. They generate steadily increasing sales figures for their manufacturers and users just as reliably. And that, even though their huge, boundary-shifting time has only just begun. Because soon enough, robots will use artificial intelligence to catapult industrial production into spheres that were previously unimaginable.

Robots are definitely a model for success. Maybe not on the catwalk yet, where they probably will not look good in the future too – rather awkward-looking – but in production. Impressive figures from the International Federation of Robotics (IFR) demonstrate just how much their use in industry, and so also for pipe production, has changed purely in terms of quantity. In 2008, the number of industrial robotics units worldwide was still 113,000. In 2018 this number climbed to 384,000 units. Where it will end is completely open!

China, the biggest customer
The Asian-Australian market relies heavily on the support of robots. The demand was for 260,000 units last year, 71,000 in Europe and 49,000 in America. China remains by far the largest customer – according to IFR estimates, it acquired 133,000 in 2018, followed by Japan with just over 52,000 units. The USA, the third largest market for robots, made a notable 15 % leap to a total of 38,000 units last year.

“The North American countries – US, Canada and Mexico – represent the second largest operating base of industrial robots in the world after China,” said IFR president Junji Tsuda, president of the International Federation of Robotics. While many major robot system integrators came from North America, most major robot manufacturers are located in Japan, Korea and Europe.

Closed process chains
Love that lasts: robots remain in demand – even in the face of global economic and political uncertainties. Germany as example: according to the German Mechanical Engineering Industry Association (VDMA), German robotics and automation achieved a sales volume of 15 billion euros for the first-time in 2018 – an increase of 4 %.

“Geographically, the strongest development of course take place in the markets which today still completely or partially dispense with automation,” explains Stefanie Flaeper, Managing Director at transfluid. Wherever employees can exert qualitative influence on products, the potential is also very high. “If closed process chains are desired, there is certainly great potential for growth here. This is also of interest when dealing with sensitive components.”

Automotive as the engine
The driving force behind the ever-increasing demand for robots is the automotive sector, where robot use is gaining momentum. This is followed by areas such as electrics/electronics, metal, plastics and chemical products as well as the food and beverage industry. In other words, a development that electrifies numerous industries.

The size of the company plays a key role in the use of robots. In 2018, almost every sixth company in the manufacturing sector (16 %) in Germany with at least ten employees used industrial or service robots. As the German Federal Statistical Office explains, large industrial companies use robots more frequently than smaller companies. In large companies with at least 250 employees, the proportion is 53 %. In medium-sized companies with 50 to 249 employees, it is 24 %. With a share of 10 %, small companies with 10 to 49 employees use robot technology much less frequently. “Industrial robots are used, for example, for welding, laser cutting and special-purpose painting,” reports the Federal Statistical Office. Service robots would be used for monitoring, transportation and cleaning purposes.

Shoulder to shoulder
The robot works like clockwork and provides impetus to the company's sales. A pat on the back would be appropriate – if it would have meant something to a robot. Simply as a thank you for doing its job in production repetitively with the same precision.

The advantages of the robot in industry are obvious: These include “increased productivity, production reliability, stable processes, ‘closed’ production processes – with a finished part – and linking also in difficult positioning,” explains transfluid CEO Stefanie Flaeper.

However, robots are usually “lone warriors”. They are often separated from humans by a safety fence. But this is likely to change with the use of artificial intelligence in the future, when robot and man work shoulder to shoulder. What would have been considered science fiction years ago, is slowly but surely becoming reality.

Imitating man
The robots will join forces with humans, take on even more tasks, assist their human colleagues to accomplish specific difficult tasks. “The challenge is to be able to use the robots even for very small production volumes, which is only partially possible today,” says Flaeper. If successful, it will open up a new field of activity for robotics. “It would also be interesting if the robot could very precisely mimic the movement of a person in a production process without having to be programmed.”

The potential of an intelligent – and “sensitive” – robot is immeasurable. “Because specified processes which can be simulated digitally and undergo corresponding evaluations are important in Industry 4.0, a robot is superior to humans,” continues Flaeper. Because the robot provides the security that the processes are always the same and could be simulated accordingly. The processes could be represented and checked via a digital twin.

Digital approach
Therefore, the limits of the possible that appeared hardly surmountable until a few years ago are shifted tirelessly not only in companies, but also in institutes and universities. The Institute for Robotics and Mechatronics, for example, is working on this. One focus of the institute is on the pilot project “Factory of the Future”. It involves the implementation of robust robot-aided manufacturing processes with the help of digitisation approaches in the context of Industry 4.0. “This includes, for example, Cobots (collaborative robots), which are as easy to use as smartphones, as well as robots that generate the necessary programs for assembly in any quantity,” explains the institute. These flexible and interconnected manufacturing processes would make applications more efficient, less expensive and safer.

As part of the EU-wide SOMA project, employees of the Institute of Robotics and Mechatronics have made significant progress in the sensitive gripping ability of robots. SOMA started with the objective of improving the state-of-the-art robot manipulation capabilities for the industry. The project has already been completed “and includes a number of scientific breakthroughs in the ability to grip and manipulate undefined objects such as fruit or vegetables with robotic hands,” explains the institute.

“Soft hands”
The traditional approach to robotic grasping and in-hand manipulation uses rigid hands and regards the environment of the object as an obstacle. Development focused on exploring ways to grasp an object without coming into contact with its surroundings.

“The SOMA project, on the other hand, uses soft hands that can easily adapt to the shape of the object and use the physical constraints of the environment as an opportunity to guide manipulation,” emphasises the Institute of Robotics and Mechatronics. This fundamental change in approach was inspired by the way people use their hands.

The SOMA consortium consists of world-renowned researchers, academics and scientists. Apart from the German Aerospace Center (DLR), employees from the Technical University of Berlin, Ocado, the University of Pisa, the IIT – Istituto Italiano di Tecnologia, and the Institute of Science and Technology Austria are cooperating.

Festo developed the “BionicSoftHand”. The human hand is a natural model for the gripper. According to the company, it will be pneumatically operated to enable the BionicSoftHand to interact safely and directly with humans. Artificial intelligence will allow “the bionic robot hand to autonomously learn to solve gripping and turning tasks, similar to the human hand in interaction with the brain”.

Efficient and productive
Robots are already proving successful in day-to-day industrial life. For example, the TWISTER® from Wafios “meets the highest standards of quality with extremely fast processing, making the manufacturing processes efficient and productive,” the company emphasises. The Twister® robot bending system is not a traditional bending machine, but “a compact all-rounder that meets the manifold requirements of bending tasks as well as the handling of the most complicated bending parts”.

The TWISTER® provides a bending system that can even be used with pipe-hose combinations. “This base, combined with a KUKA robot, forms an unbeatable team,” says Wafios. This technique allows the system to achieve a significant increase in productivity.

MiiC OPTON (Europe) is also continuously developing its robots. For example, a MiiC OPTON (Europe) 6-axis robot with bending head is guided on a bed. The robot traverses the guideway to bend a work piece, which is held by the chuck in a fixed location. “In its driving mode, the robot performs loading, unloading, all movements of the feed between two bending points as well as rotation and bending,” explains the company.

Energy and data
There are many things to consider in the field of robotics, for example, energy and data management. Leoni developed intelligent solutions for robot energy supply and drag chains. "These make it possible to avoid the unplanned shutdowns of a plant and so reduce maintenance costs," explains Leoni. This makes production more efficient.

Energy supply systems and drag chains supply energy to robots and production facilities and ensure the connection to the controller and sensors. “They are exposed to very high levels of daily production and can lead to costly unplanned production downtime when data and power cables on robots and drag chains fail due to wear.” Leoni therefore developed intelligent cable systems that actively monitor, analyse and transmit their condition. “The clear aim is to avoid downtimes in production and increase plant availability in production.”

Lucrative orders
Investments in robotics have long been worthwhile. For example, Leoni was commissioned by Volkswagen to equip 1,300 robots for the manufacture of electric vehicles from the MEB (Modular Electrification Modular System) platform at its Zwickau site with the LSH3 hose package solution. This way Leoni assists VW in the conversion of the production site for combustion vehicles to a pure e-mobility site, which should be completed by the end of 2020.

At the VW production site in Zwickau, Leoni equips the robots with the LSH3 hose package solution for joining techniques such as welding, handling, lasering, clinching or gluing. In addition, the project includes the installation of floor wire sets, in other words, the wiring from the robot or the stationary tool to the robot controller.

The development around robotics is speeding forward in the fast lane. Companies who want to stay on the inside track to success should therefore take a very close look at them. Because lucrative orders beckon.

News and trends on robotics will be presented at wire and Tube Düsseldorf from 30 March to 3 April 2020 at Düsseldorf Fairgrounds.

New Equipment for Tube Manufacturing

tube 2016Part 1: Asia, East Europe and South America  
New, modern tube plants are emerging worldwide on a continuous basis. Currently, the primary geographic areas affected are Asia, East Europe, South America and, most importantly, the USA. German companies – particularly from North Rhine-Westphalia – are partners in many of these projects, participating either in the entire manufacturing plant or in partial areas.  

The German machinery and plant engineering sector is expecting actual growth at the rate of approximately three percent in 2014. Outgoing VDMA president Dr. Thomas Lindner announced this prognosis during the general meeting – which takes place every three years – in October 2013 in Stuttgart. The industry managed to recover almost fully from the slump of 2009 with a 24 % increase in production in the years between 2010 and 2012. The economists at VDMA expect a production value of EUR 195 billion for 2013 – the same amount as in 2012.  

The decline in turnover in the metallurgical plants and rolling mill equipment sector recorded in 2011 and 2012 is expected to level off. For this reason, the VDMA association for metallurgical plants and rolling mills predicts a slight stabilisation in the course of the year for 2013. As of mid-2013, the trade association was forecasting a 5 % increase in turnover and a 4 % increase in incoming orders for the year. Admittedly, not everyone is happy about new plants – especially when they result in increased capacity. “Excess capacity remains a fundamental problem in the world markets,” writes for example the German Steel Tube Association in its current annual report for 2012. “The Chinese manufacturers’ capacity expansion – which seems to lack sufficient market-economy based scrutiny – occurs particularly threatening.”  

German manufacturers of metallurgical plants and rolling mill equipment play a significant role in this sector – not only economically. Their products also enjoy an excellent reputation for their solid engineering. Among other factors, this is in part due to the fact that the industry has managed repeatedly “to offer plant and machine design concepts that enable customers to manufacture their products more competitively,” according to Heinrich Weiss, Chairman of the Supervisory Board of the SMS Group in Düsseldorf.  

Higher Efficiency and Profitability in Tube Manufacturing
SMS Meer in Mönchengladbach is responsible for the tube sector as a business group. It is here that the directube® method was developed, which allows more efficient and economical production of copper tubes than before. Next to reduced production costs, the quality of the finished products, energy efficiency and environmental considerations – as well as efficient use of raw and input materials – were primary focal points of the development.  

With directube® copper tube production, copper cathodes are formed directly into mother tubes. Compared to the traditional extrusion process with subsequent cold pilger rolling, the directube® process saves several time-consuming intermediate steps: extrusion, preheating and one of two intermediate annealing stages.

The directube® method consists basically of two production stages. In the first stage, the copper cathodes are melted down, tube shells are continuously cast in multiple strands, and the surfaces are milled. In the second stage, the tube shells are cross-rolled in a planetary cross-rolling mill and coiled. Finally, the mother tubes are process into the desired end products.

The steel tube production process is being further developed with the same tenacity. A new detaching mill developed by SMS Meer for a Voestalpine Tubulars plant at the Kindberg, Austria location promises to deliver a high level of plant availability and product quality. As a technological innovation, the detaching mill features a hydraulic quick-release mechanism that ensures speedy lifting of the mill in the case of a jam, preventing damage to the product and the machine.

Seamless Tubes up to 20 Inches in Diameter
There is also news to report in the area of dimensions of seamless tubes. After around two years of construction, Jiangsu Tianhuai Steel Pipe (Jiangsu, China) began operating a new 20" PQF tube rolling plant for seamless precision tubes in late 2012. The new plant – the world's largest continuous tube rolling plant – is equipped to produce seamless tubes up to 53 mm in diameter. The plant has a production capacity of 500,000 tons per year. "The maximum diameter of 20 inches is a record," rejoices SMS Meer Project Director, Roland Preuten. "This opens the door to an entirely new performance level for PQF seamless tubes."

Developed by SMS Meer, PQF (Premium Quality Finishing) technology is designed to ensure a continuously high level of tube quality inside of tight tolerances, as well as reliably high productivity. For the 20" tubes, SMS Meer designed the largest cone-type cross-roll piercing mill with a roll diameter of 1,700 mm. Since a PQF rolling mill has three rolls that uniformly encompass the tube, it distributes the force much more evenly than the conventional two-roll configuration.

A new groove-dressing machine is slated to go into operation in the production of seamless tubing at Interpipe Niko Tube in Nikopol, Ukraine in early 2014. According to SMS Meer, this three-axis groove-dressing machine improves production accuracy while shortening processing time. With the KR III 33 CNC groove-dressing machine, grooves in the rolls are fully automatically machined. Each operation takes less than 30 minutes. A measuring mechanism automatically records the stand and roll data, making it easy to modify the groove forms.

Increased Productivity in Tube Welding Lines
SMS Meer developed a tube welding line for Arvedi Metalfer Do Brasil in Salto (Brazil) that is designed for a capacity of 150,000 tons per year. The range of dimensions includes tube diameters from 33.4 mm to 139.7 mm and wall thicknesses from 1.5 mm to 8.0 mm. Tube lengths from 5.0 m to 12.6 m are possible. The tube welding line is capable of a maximum production speed of 130 m per minute. With the new line, Arvedi is able to manufacture precision thick-walled tubes with round, square and rectangular cross-sections.

"Thanks to the innovative quick-change systems, the line is on average about 30 percent more productive than conventional solutions," explains Michael Cottin, Vice President – Welded Tube Plants at SMS Meer. "In addition, Arvedi can adapt flexibly to changes in market requirements for welded tubes. Orders for increasingly small lot sizes with a variety of dimensions require plant solutions with short changeover times and minimal downtimes."

These newly developed inline and offline quick-change systems make changeovers to new tube dimensions possible in as little as 90 minutes to two hours. SMS Meer's CSS Quicksetting System plays a special role in this: Among other things, this computer-controlled system ensures that the rolls are automatically set exactly to the required working position after such a dimension change.

Expanding and Straightening on One Machine
SMS Meer designed a mechanical expander with a newly developed straightener for a Tenaris Confab S.A. tube rolling plant in Pindamonhangaba, near São Paulo in Brazil. The innovative AGT (Advanced Geometry Technology) allows precise calibration and straightening of longitudinally welded pipes with small diameters and large wall thicknesses on a single machine. Pipes such as these are required for offshore pipelines that are laid in extremely deep waters. Tenaris Confab produces up to 450,000 tons of tubing annually, in diameters ranging from 12" to 48" and wall thicknesses from 6.4 mm to 40 mm. The longest tubes produced by Tenaris are 12.5 metres.

According to SMS Meer, AGT is a flexible and efficient solution for straightening large pipes that become bent due to the heat supply during submerged-arc welding. For the first time, pipes can be straightened selectively in all directions during expansion, eliminating the need for downstream straighteners. Compared to conventional solutions, this new design is expected to produce better straightening results via over-bending. Moreover, strain on the expander mechanism is minimized. The machine is designed for diameters up to 30 inches. In the case of larger diameters, the units can be entirely separated from the machine, which also allows for easy tool change.

More Cost-Efficient Production of Small, Thick-Walled Tubes
A new gap closing press developed by SMS Meer with a press force of 25 MN was constructed for Izhorsky Trubny Zavod (ITZ) of Kolpino, near St. Petersburg (Russia). The new press allows for more cost-efficient production of tubes with small diameters and large wall thicknesses. The new method promises to triple productivity compared with a single JCO long-stroke press.

First, heavy plates are formed quickly and precisely using a JCO pipe forming press. The remaining gap is then reduced to a minimum in just a few steps using the new gap closing press – a requirement for a safe tack welding process.  The result is highest quality pipes with extremely low tolerances for demanding applications. In addition, the new gap closing press is the first to utilize the VSP (Variable Speed Pump) technology. According to SMS, this modern and extremely efficient hydraulic drive offers a significant reduction in energy and maintenance costs.

Also in Russia, JSC Vyksa Steel Works in Vyksa successfully put a new gap closing press from SMS Meer into operation in late 2013. With the new machine, the company has modernized its large-diameter pipe production line while significantly increasing its productivity. Pipes with these special dimensions are required in particular for offshore pipelines. The specially adapted forming and closing processes are controlled by the SHAPE software developed by SMS Meer, resulting in high-quality pipes with very low tolerances for demanding applications. This gap closing press also features VSP variable speed pump control, which reduces the machine's energy consumption by up to 50 percent compared to earlier-generation machines.

Pressure Control System with Reduced Cycle Time
Salzgitter Mannesmann Line Pipe (SMLP) in Siegen, Germany has been using the globally unique HTM (Hydrostatic Testing Machine) from spiral tube manufacturer PWS since the second quarter of 2013. With this machine, up to three pipes of different lengths can be tested simultaneously on three test stations, with a total cycle time of only 48 seconds (for 16 inches/12 meters). This represents a time saving of 30 percent per test. Moreover, it is possible to test different diameters and lengths simultaneously. Each section can be individually and independently controlled.

"The new facility marks a significant improvement of the strategy for hydrotesting and pipe manufacturing," states Michael Stark of PWS. "The need to sort out shorter pipe lengths during the manufacturing process for testing at a later time is eliminated, which is an enormous advantage in terms of production logistics and throughput. The extremely fast and extraordinarily precise pressure control system rounds off the technology package." Thanks to its state-of-the-art technology, the modern pressure control system offers a high level of flexibility and efficiency.

Part 2 of the article covers new tube manufacturing plants in the USA. The significant increase in gas and oil production there is causing local and foreign manufacturers to invest in new tube mills. This benefits plant manufacturers worldwide, who of course also participate as exhibitors at the world leading trade fair Tube. The next international tube and pipe trade fair takes place from 4 to 8 April 2016, once again simultaneously with the international leading trade fair wire in Düsseldorf.

Published inEquipment

The aerospace tubular parts manufacturer SL Engineering is continuing its investment in advanced automation with the acquisition of a second all-electric CNC tube bending machine from Unison.

The new machine enhances SL Engineering's manufacturing capabilities, especially its ability to produce more complex tubular shapes. It also extends the size range of tubing that can be bent using all-electric servomotor-controlled movement - to tube and pipe diameters up to 80 mm. 

2014-04-24 074320"Engine and aircraft manufacturers are taking advantage of the advanced shape forming capability of state-of-the-art tube bending machines by specifying more complex shapes and highly challenging tighter-radius bends - to save weight and space and eliminate welded joints," says Shaun Stevenson of SL Engineering. "The sophisticated bending capability of Unison machines, which allow greater control over tube clamp and carriage push forces, helps us to achieve these new levels of precision. If we did the same jobs on our old hydraulic machines we would be much more reliant on highly skilled operators to bothset up the machines, and make the parts with additional weld joints, and hence additional cost."

SL Engineering (SLE) is one of Europe's leading Tier 1 suppliers of rigid tube assemblies and precision machined parts for aerospace applications, and supplies components to major engine and airframe programs from commercial Airbus and Boeing aircraft to leading military programs such as the Joint Strike Fighter (JSF). Although the aerospace sector accounts for a large proportion of turnover, SLE also provides parts for industrial gas turbines, marine propulsion, and other critical industry applications.

SLE's business today is characterised by a need for manufacturing flexibility. The average batch is around 5 to 25 parts, and orders can even be for just a single emergency 'aircraft-on-ground' part. Demand for greater precision and shape complexity is another major facet of its work. Until recently, few tubular parts required bends with radii of less than 2D (twice the tube diameter). Today, however SLE regularly receives requests for bends of 1D, and for shapes with minimal straight sections between bends. The use of thinner walled tubing, and expensive specialist materials such as titanium and Inconel are further trends.

These demands are behind the company's moves to all-electric tube bending technology. SLE installed its first such bending machine in 2010 - a 30 mm diameter Breeze from the UK manufacturer Unison. Much of SLE's work is on diameters of 30 mm or less, and most of its current work falls into the sub-50.8 mm range. The first all-electric machine has proved critical for SLE, allowing it to handle small batch set-ups much more efficiently and quickly - with zero or minimal scrap. As a result, the company channels most new work for smaller parts onto the 30mm all-electric machine, and transfers many older parts onto the machine by creating new bending programs as orders come in. After almost four years of operation, the 30 mm machine now produces a significant proportion of SLE's business. SLE typically has anywhere from 500 to 1000 live jobs at any one time.

The latest machine that SLE has acquired, a Unison Breeze 80, now gives the company all-electric CNC tube bending options for tube diameters up to 80 mm. The machine also incorporates a multistack/multiradius tooling capability. This feature is a critical aspect of achieving some of the complex tubular part shapes and multiple bend sequences that are being specified on today's aerospace programs.

"We continue to see many challenging opportunities in the sector, but it does require significant capital investment," adds Stevenson. "The new Unison bender, along with further investments in 5-axis machining, has helped SLE take its manufacturing capability to a new level. We can meet the most complex tube assembly specifications that aerospace companies require today, and the combination of advanced machinery and our know-how gives us a platform to raise the bar even higher, and differentiate SLE from our competitors. Another service we offer to clients who are able to provide us with pre-release drawings, is evaluating manufacturability and advising on the potential for manufacturing and cost saving improvements before final drawing release."

As an example of the exacting specifications that SLE faces, one current part for a military fighter program calls for a shape with multiple 2D bends but minimal straight sections between bends, using thin wall titanium tubing. Tube ovality also has to be less than 5% after bending - as compared with an industry norm of 10% - and the part shape has a positional and length tolerance of just +/- 0.005 inches after bending and welding. As the part is made from titanium, bending must be right first time as adjustments after shape forming are almost impossible. The consistency and repeatability of the Unison machine is a critical enabler for fabricating this part, as well as other titanium tube parts that SLE currently makes.

Another aspect of the advantages of the Unison machine for a contractor such as SLE is the ease of programming. Tubes are often the last parts to be defined and designed - whether they are for an engine or airframe. Using its own bespoke macro-driven CATIA V5 closed-loop CAD/CAM facility, and Unison's three-dimensional simulator, SLE can create new CNC bending programs for the Unison machine very rapidly - providing ideal support for clients that are unable to supply tube/pipe details until the very late stages of projects.

"All-electric tube bending technology has given this client both a rapid return on investment, and a means of tackling emerging challenges such as bending exotic materials," adds Steve Haddrell of Unison. 

SL Engineering Ltd has the fullrange of in-house resources required to offer complete solutions for the manufacture of specialised rigid tube assemblies and precision machined components used in some of the most demanding applications in the aerospace, industrial gas turbine, marine, oil and gas, and medical industries. Founded in 1959, SL Engineering has always specialised in high-precision tubular assemblies - from a starting point of products for motorsports applications. Today, the company employs around 50 staff. Its core capabilities include CNC tube manipulation, CMM tube inspection, multi-axis CNC machining for manufacturing complex end fittings, plus all required support processes including welding, brazing, assembly, pressure testing, and NDT (dye penetrant and x-ray inspection). To support its work in aerospace, SL Engineering has attained qualification to many key industry standards including AS9100 (Rev C) aerospace quality management systems, BS EN ISO9001, and NADCAP special process approvals for welding, brazing and NDT. To reinforce its position as a leading tube assembly specialist, SLE has also achieved SC21 award status for the last three consecutive years - making it one of the top performing aerospace organizations in the UK in terms of business performance and continual improvement. This performance has been all the more impressive as SLE also achieved 22% growth in business during 2013.

2014-04-11 104011The new ferritic steel grade VM12-SHC developed by Vallourec has been certificated by ASME (Code Case 2781). It has already been used successfully for many years in European design for modern high temperature power plants and heat recovery steam generators (HRSG) and can now be used for all ASME design. In addition, the product is optimally suited for replacing grade X20CrMoV11-1 superheater pipes in existing power plants. VM12-SHC extends Vallourec's range of ferritic seamless steel tubes for power plants. At the same time, it underpins Vallourec's claim to technological leadership in an application area characterized by extremely high quality demands.

The last three letters of “VM12-SHC” refer to one of the new steel's key properties. Standing for "super high corrosion resistant", they qualify tubes made from this grade for extremely corrosive steam-carrying pipes for high-temperature applications up to 620 °C. The steel's special chemical composition puts it in a performance class unparalleled in its category in terms of creep strength and resistance to steam oxidation.

Outstanding material properties

The ASME certification procedures provided an ideal opportunity for new VM12-SHC to demonstrate its extraordinary behavior under the obligatory tests and checks. As shown by the test results, the steel combines excellent mechanical and physical properties with an oxidation resistance comparable to that of the austenitic steel grade TP347FG and surpassing those of steel grades T91 and T92 by far.

Proven in tests and demanding power plant applications

One of the most important criteria relevant to a material's suitability for a given application is its processing behavior, notably in terms of cold bending properties and weldability. Here too, VM12-SHC passed all the standardized tests (e.g. creep tests, creep rupture tests on tube bends and stress crack detection after welding) with flying colors. Practical experience was already generated on the basis of applications in state-of-the-art coal-fired and combined-cycle power plants in European design.

VM12-SHC is produced at European Vallourec locations. Tubes in the new steel grade are available heat-treated and with wall thicknesses of up to 12 mm.

Manufacture of multi-level warehouses for storing and retrieving bar, tube, sheet and other material automatically, and production of an extensive range of sawing machines for cutting material accurately, are the two specialisms of the German firm, KASTO, whose UK subsidiary will be exhibiting at MACH 2014. The group, which has recently entered its sixth generation of family ownership and management, is celebrating its 170th anniversary this year.

Better known for its high performance sawing products, the company has been actively promoting its workshop / dealer range of machines for the past year. The programme comprises smaller bandsaws, circular saws and hacksaws and MACH 2014 will be the first time that all three ranges will have been shown at a national exhibition. Aimed at jobbing shops, they are designed alongside the company's high-end sawing machines and are manufactured at the company's factory in Schalkau/Thueringen.

The saws range from pull-down models priced at a couple of thousand pounds to automatic machines costing ten times more. During 2013, marketed under the slogan 'quality for all budgets' and supported by a new website www.kasto.uk.com, they accounted for 35 per cent of sawing machine sales by value in the UK, up from 20 per cent the previous year.

The three models on display will be the KASTOfunctional U bandsaw with length stop arrangement, the KASTOradial M6 circular pull-down saw, and the KASTOhbs1 power hacksaw.


KASTOfunctional U

The KASTOfunctional pivot-type bandsawing machine with hydraulic infeed is available in manual, semi-automatic and fully-automatic versions, with suffixes M, U and A respectively. The semi-automatic machine will be on the stand at MACH.

It is of solid construction with a robust, torsion-free welded base for rigorous use in workshops, capable of cutting material up to 260 mm round / square. Mitre-cutting to the left at up to 45 degrees and to the right at up to 60 degrees can be performed on tube, section and solid material. The mitre angle can be adjusted without having to alter the material position to achieve the correct cut length.

Precise ballscrew drive ensures exact positioning of the stock prior to cutting. The hydraulically actuated, horizontal clamping vice ensures accurate sawing to length without slippage and also allows short rest pieces, minimising material wastage. Cutting speed is infinitely adjustable from 20 to 110 m/min to suit any type of metal, even tough varieties. The BasicControl with swivelling operator’s panel ensures optimum machine operation via function keys. Up to 98 programs can be preselected.

KASTOradial M6

KASTOradial is a family of cold circular saws including four manual, pull-down versions designated M4, M6, M7 and M10 and two semi-automatic models, U7 and U10.

With two cutting speeds for universal use in workshops, the KASTOradial M6 is ideal for straight cuts and mitre cutting on both sides within 45 degrees. A double vice with quick clamping lever provides security for holding bar stock. A 315 mm diameter HSS saw blade, length measuring stop and re-circulating coolant system are standard equipment.


For around half the price of a workshop range bandsaw, the KASTOhbs1 power hacksaw provides an economical alternative facility for cutting. Used widely in workshops, including on ships, the design is popular for jobbing applications on a variety of metals where space is limited, performance is of secondary importance and small volumes of cut pieces are involved.

The KASTOhbs 1 is a hydraulic, semi-automatic model with two cutting speeds in a pushing, arched cutting motion invented by KASTO in 1947. Cutting pressure is infinitely adjustable. Requiring minimal floor space, the machine is designed for light to medium workshop use and is ideal for cutting profiles, beams and solids. Mitre cutting from 0 to 45 degrees extends the machine's versatility.


There will be demonstrations of a high-performance, 430 mm-capacity KASTOtec AC4 KPC bandsaw cutting 200 mm diameter, 316 stainless steel in 3.8 minutes minutes using a coated carbide blade running at 70 m/min. The emphasis will be on the measures that have been taken to manage and minimise vibration, which leads to higher band speeds and feeds, increased production output, lower noise levels, better accuracy and surface finish, and longer blade life.

Bandsawing productivity has increased by 300 to 400 per cent with KASTOtec bandsaws that have been factory-fitted with KPC (KASTO Performance Cutting) technology. It takes a holistic view of all aspects of the bandsawing process including blade guidance and monitoring, cutting parameters for the material, machine construction, coolant delivery, the control system and blade selection.

KASTOtec AC-series machines feature a steel / mineral cast composite construction that is six to eight times more vibration-absorbing than cast iron. The machine has a powerful main drive through a rigid, play-free, spur bevel gear delivering 98 per cent of the available power directly to the drive wheels.

High precision cuts are a result of having blade guides as close as possible to the stock on both sides and maintenance-free linear guides for the hydraulic infeed. Together with feedback of cutting force, blade speed and position, they provide consistent feed per tooth, irrespective of the ambient temperature.

Overlaid on this already high specification is the new KPC package, which KASTO has developed to improve cutting productivity still further. The focus has been on minimising vibration during cutting. Key steps taken include new blade guidance on both sides of the cutting area (patent pending) and a novel measure to dampen vibrations using a so-called ‘Trumguide’ system.

Central to the step-change in performance, it is a simple yet effective device. Two spring-loaded tensioner guides are mounted at the returning side of the blade, inside the top of the saw head guarding at either end. These guides have the effect of suppressing vibration on the side opposite to the cutting action.

KASTOunitower C

A KASTOunitower C storage tower for sheet metal will occupy a large area of the stand. The space-saving tower stores 3 metre by 1.5 metre sheets, plates, flat products and other materials such as bar, tube, boxes and semi-finished goods in a compact footprint. It offers many advantages compared to conventional storage on shelves, cantilever arms or on the floor.

The tower is especially suitable for job shops, machine shops and small to medium size sheet metal processing facilities, providing flexible storage to a height of up to 7.2 metres. It has a compact footprint of 3,415 x 4,350 mm and the standard version has a storage location every 47 mm.

The pallets holding the sheet metal glide on almost wear-free, plastic-lined tracks when pushed into or pulled out of a storage location within the steel structure. A lift mechanism travelling at the front of the tower effects horizontal transfer of the material as well as traversing vertically between locations at up to 8 m/min.

Depending on design, pallets can support a maximum load of either 1,200 kg or 3,000 kg. The height of the loading / unloading station is adjustable, allowing direct transfer to a sheet metal processing machine or transport cart. This raises production efficiency, improves safety, saves labour and minimises the risk of damaging the material.

Versions of the KASTOunitower C are available for semi-automatic or fully automatic operation, with appropriate safety measures. The tower is controlled by KASTO's own BasicControl, which is fitted with a user-friendly touch panel.

170th anniversary

To coincide with its 170th anniversary, the KASTO group will unveil a revolutionary new product range on 7th May 2014 during an open house to be held at its headquarters and main factory in Achern, southern Germany. The company is saying little about its new product before the launch, but the implications are that it represents a major step forward in bandsawing technology and in the company's manufacturing process.

On 18th, 19th and 20th June, the Milton Keynes subsidiary will hold open days at its showroom and technical centre. The new machine will be on show again, along with many other bandsaws, circular saws and hacksaws from the manufacturer's wide range of products. Automated warehousing of bar, tube, profile and flat material will also be demonstrated.

Turbex MACH 2014 preview information


Turbex will launch at MACH 2014 a fully automated version of the ultrasonic Versa cleaning line fitted with a new basket transportation system under programmable logic control. The lines are among the most compact and capable aqueous cleaning systems on the market.

Bespoke installations built from modular tanks and components are capable of washing, degreasing, rinsing and drying batches of industrial components to a high degree of cleanliness and uniformity. A customer may specify any combination of processes to define a system that can be expanded or altered after installation, if required.

Typical cleaning processes include ultrasonic or immersed jet cleaning, single or multiple water rinsing, and hot air drying. Particle filtration as well as oil separation can be included, according to customer requirement. A PLC with user-friendly operator interface allows convenient control over all machine functions.

Another facet of the design is the inclusion of degassing as standard. This removes air dissolved in the water resulting from emptying and filling a tank. Presence of air is undesirable, as it takes energy out of the ultrasonic action and reduces its effectiveness.


The Elba cleaning machine from Turbex.

Basket and jets move independently

Turbex will show the Elba model from its range of spray cleaning machines. Intended for high precision applications, the machine uses a world patented system whereby the movements of the holding basket and the spray jets are individually adjustable, allowing them to rotate in the same or opposite directions.

Each program can therefore be tailored, together with other movement options such as rocking of the basket, to clean efficiently even the most complex of parts. Another notable point about these high quality machines is that they have integral condensing systems, so there is no need for extraction to be fitted.

The machine has a dual wash tank, integrated warm air drying and an easy to use control that stores cleaning programs without complicated codes. A folding loading door is standard, although a vertical sliding door can be specified for use with automatic basket transfer for unmanned operation.

Processing of larger components

A heavy duty Turbex aqueous washing machine will be on the stand, designated AC-1.3, from the supplier's range of front-loading, spray washing and rinsing models. They have proved particularly popular in the UK for degreasing, precision cleaning, phosphating, paint removal, de-rusting and de-scaling.

Manufactured from stainless steel, the AC programme comprises both single- and multi-stage units with options for one, two or three process tanks. Standard sizes range from one to two metres in diameter, although larger machine sizes are available.

These PLC-controlled machines provide a high level of cleaning performance due to ingenious design principles combined with high spray pressures and liquid flow rates achieved by the powerful pump. The spray system, also of stainless steel, rotates around a fixed load that can weigh several tonnes. Acoustic as well as thermal insulation protect operators from undue noise and heat.

Air blast and hot air drying stages are optional, as is gas instead of electric heating. Other optional accessories include steam extraction, automatic refill, an oil skimmer or separator and a detergent dosing unit. A manually operated spray lance with its own impeller pump can also be supplied, allowing particularly awkward soils to be removed. Alternatively, temporary use of the equipment as a manual spray booth is possible.

Bench-top ultrasonic machines

Completing the exhibits at the show will be models from the Turbex range of bench-top ultrasonic cleaning tanks, which can be used stand-alone, as bench-mounted units or as part of an integrated modular cleaning system.

Available in a variety of sizes, they feature a welded stainless steel tank, double lid with thermal and acoustic insulation, thermostatically controlled indirect heating in the side walls, and an electronic control with digital time / temperature display. A level guard cuts off the heating and ultrasonics if there is insufficient liquid in the tank.

A range of options is available, such as stainless steel work baskets, filtration, a storage tank with oil separator, and a hot air dryer.

Revolution by Lang Tube Tec

Specialist to launch new lifting table for tube bending machines at the "Tube" in Düsseldorf – Hall 5, Stand G16

The specialist's world première: Lang Tube Tec – the Lorsch-based supplier of quality products – is set to revolutionise the market for tube bending machines with the introduction of an entirely new processing concept. Lang Tube Tec will be using its presence at the Tube in Düsseldorf (Hall 5, Stand G16) to launch the new 80CNC-EMR – the world's first fully electrically-powered automatic bending machine to use a lifting table that creates vertical shift of collet rotation and mandrel retract both at the same time.

80 CNC

The integrated booster for applying additional pressure on the pipe while it is being bent is also driven on the lifting table during the same stage of work. Other highlights of Lang Tube Tec's CNC-E series include the drive-click system for storing motor parameters as well as the entirely new control with intuitive graphic user interface and torque-controlled tube clamping. The model being shown in Düsseldorf will also be equipped with an optical weld seam scanning device that helps always correctly and precisely align the tube's weld seam.

"The new machine concept will enable our customers to break entirely new ground in regard to machine rigidity and machining quality. It will also help considerably reduce set-up times, which will in turn increase productivity," said Head of Sales, Sabine Neff, outlining the innovation's most important benefits. The technological advances mean that it is highly suited for employment in the automotive and commercial-vehicle sectors as well as in the fields of aerospace and shipbuilding.

Compared with the otherwise conventional methods where collet rotation and mandrel retract shifting are effected separately, Lang Tube Tec's innovation realises the benefits of greater rigidity, 100% synchronicity of both units' movement and the decisive advantage that the high booster forces may be applied directly and centrally. "Our new concept means that we're able to prevent the high levels of torque from affecting the sensitive ball bearing spindles," explained Service and Project Manager, Björn Brunner.

Lang Tube Tec's lifting table concept also offers massive benefits over conventional machining processes where the bending head is moved vertically: even with increasing machine sizes, users will still be able to position the tubes at the ergonomically optimised operating height of 1,150 mm and carry out tool changes without straining their backs. Both minimise set-up times and ensure that the machine can be taken quickly into operation so that jobs can be completed even faster. The new machine control with the Siemens Simotion CNC also stands for the speedy and safe execution of work flows because all axes are moved simultaneously.

The fact that the user interface is so intuitive also means that Lang Tube Tec's CNC-E series may even be operated by people without previous CNC training. And because the clamping and feeding forces are torque-controlled, the machine automatically compensates for fluctuations in tube batches. A high-performance simulation program allows the tubes' bending properties to be checked in advance so that any necessary corrections may be made before they are worked. It also allows binary-coded 3D models to be imported to prevent any input errors.

The tools and bending programs used with the 80CNC-EMR may be programmed quickly and the fact that all parameters are stored in the memory means that the machine is always ready for use and doesn't have to be run in beforehand. The bending tools may be changed particularly quickly, the pressure die is simply hung into the T-grooves, the clamp dies slid into the circular guide and the tie rods may be swivelled after the locking pins have been released. The concept may be adapted to existing tool systems.

The fact that maintenance-intensive gas-pressure springs are no longer needed to support the bending head and ball-bearing spindles means that Lang Tube Tec's 80CNC-EMR considerably reduces maintenance requirements while the machine's entirely new enclosure and the concept that uses a separate switch cabinet also allow optimum access for maintenance.

Innovative tube bending CADCAM solution

An innovative PC-based CADCAM solution for tubular metal fabricators who use SolidWorks CAD software, that enables them to reduce order processing and pre-production development time from hours to minutes, has been launched by the tube bending machine builder Unison.

The software automatically extracts key manufacturing information, including tube specifications and CNC bending data, from both native SolidWorks models and common CAD file formats such as STEP, IGES, and ParaSolid. It can handle tube models with round (tube and bar), square, rectangular, oval or flat-sided oval cross-sections.

2014-01-29 095922

Unison has secured exclusive worldwide sales for the new software add-in – called TubeWorks – from its developer, 3DCompound Ltd.

3DCompound, a UK-based software consultancy, specialises in the development of third-party value-added products for the highly popular ‘SolidWorks’ mechanical design software. The company was founded by an accredited SolidWorks Elite Application Engineer with an extensive background in CAD and tube bending technology. It produces a variety of innovative software tools, ranging from macros to fully integrated add-in modules, which enable SolidWorks users and their organisations to realise major savings in the time and capital cost of application-specific processes.

According to Alan Pickering, MD of Unison, “Automating the extraction of manufacturing data from CAD files helps bending machine users to create production-ready programs much more quickly and efficiently. TubeWorks will provide our customers with an enormous competitive advantage and is an important addition to our growing portfolio of software tools. As well as offering a smart solution for metal fabricators seeking to accelerate their request-for-quotation (RFQ) procedures, the software will help companies with in-house bending machines to reduce design-to-manufacturing times.”

3DCompound’s MD, Ali Jani, adds: “We chose Unison as a partner because its innovative culture matches well with our own. Unison’s all-electric tube bending machines are widely regarded as some of the best in the industry, enabling companies to push performance boundaries in metal tube fabrication. Our new TubeWorks add-in is designed with the same principles and for the same markets – we believe that the software provides users with a unique and powerful means of enhancing the productivity of their tube bending operations.”

The TubeWorks add-in is fully integrated into SolidWorks, allowing users to take full advantage of the CAD software’s powerful design functions, and eliminates the need for any additional standalone solutions for generating manufacturing data during the design, development and production of tubular parts. The add-in software is inherently intuitive and easy to use, requires no special training and can be mastered within 10 minutes.

In addition to its manufacturing data extraction capabilities, TubeWorks offers a host of powerful functions to further help users minimise the pre-production design time of machine-based tube bending. These include automated centreline creation through tubular geometry (for both round and non-round profiles) and automated conversion of imported tube models into native SolidWorks models for CLR (centreline radius) modification. The software also extensively automates the generation of 2D drawings, as well as the creation of reports for the YBC data that will be used to control the bending machine and for the XYZ coordinates of the modelled tube.

To maximise flexibility and ease of use, TubeWorks is fully functional in a multi-body part environment. A searchable tooling log enables users to quickly check the types of tools – such as bend former, mandrels, wiper dies, etc – that will be necessary for a particular bending operation, while a tooling recommendation function verifies whether a part can be produced using existing tools, or suggests suitable substitutes. The software also includes an extremely useful tube length calculator, which evaluates the total length of tube that will be needed for fabricating the specific formed part.

Unison also offers on-demand WebEx demonstrations of TubeWorks to registered customers, via its website.

tube russia

The 14th Metallurgy Litmash, Tube Russia, Aluminium / Non-Ferrous 2014 follows on from the successful event held in June 2013. 3 to 6 June 2014 will see the trade fair being staged again at the Moscow fair grounds Expocentre. The trade fair trio confirms once more its leading function as the most important trade and contact platform for the metallurgical and tube sectors in Russia and its neighbouring states. The quality metal and tube processing and finishing range offered at this year’s event attracted a total of 330 exhibitors and 10,850 visitors from 51 countries to Moscow; of the visitors 95% were trade visitors and 68% came from top and middle management. The amount of foundry technology visitors increased considerably over the previous year.

The trade fair makes it perfectly clear that Russia and its neighbouring states are among the fastest growing regions worldwide. The Russian market for machinery and equipment is lucrative and forecasts say that demand for metal working machines in Russia will triple by 2016 reaching an annual volume of EUR 2.5 billion. The investment made by Russian and foreign enterprises in the modernisation or construction of new production lines in the country is rising constantly. German manufacturers are both sought-after suppliers and investors. For Metallurgy Litmash, Tube Russia, Aluminium/ Non-Ferrous this means: the demand for high-calibre ranges from international manufacturers is also rising.

Metallurgy Litmash, Tube Russia and Aluminium/ Non-Ferrous 2014 receives valuable support from VDMA e.V. (German Engineering Federation), from EUnited Metallurgy (European Metallurgical Equipment Association), from CECOF (The European Committee of Industrial Furnace and Heating Equipment Associations) and from CEMAFON (The European Foundry Equipment Suppliers Association).

Furthermore, the ITA (International Tube Association), MC-CCPIT (Metallurgical Council of China Council for the Promotion) and AMAFOND (Italian Association of the Foundry Supplier) also provide support for the fair.

kocks pipe logoIn the course of implementing their growth strategy BENTELER STAHL/ROHR (BSR) situated in Paderborn/Germany concluded a contract with DANIELI & C., Buttrio/ Italy for a new turnkey 4 ½" seamless tube mill in the USA. The mill will be built in Shreveport, in the North-western part of Louisiana, and will be one of the largest production plants in the history of this region.

The mill is designed for an annual capacity of 320,000 t/a and will produce high-quality seamless tubes with excellent tolerances and flawless material properties according to API and ASTM-standards.

Within the framework of its cooperation with DANIELI CENTRO TUBE, Milan / Italy FRIEDRICH KOCKS GmbH & CO KG headquartered in Hilden / Germany will supply an Extracting Block type EXB 315/3 and a Stretch Reducing Block type SRB 315/30 as essential components of the hot rolling mill. Thereby, BSR has opted for rolling blocks with a modular design which are equipped with both non-adjustable and adjustable roll stands. The stands are operated with individually driven rolls and as they are interchangeable they can be used in the EXB as well as in the SRB on every stand position.

The particularities of this design (i.e. the pass remote control for the adjustable stands, the quick-changing systems for stands and rolls) considerably minimize the number of changing stands and thus the investment and operating costs, which are otherwise required for optimum production.

The automation system enables the visualization of the measured data of the rolling mill while at the same time allows the operator to control the operation, minimizing heavy ends and wall thickness variation. This translates into a consistently high production of seamless tubes of top quality and at the same time reducing operational mistakes to an utmost extent.

Production of the new seamless tube mill is scheduled for the second half of 2015.

New circular saw from KASTO

For medium- to large-batch and mass production cutting-to-length of solids, tubes and profiles in most materials, German sawing machine manufacturer, KASTO, has introduced a new, automatic circular saw called KASTOgripspeed C10. It can be fitted with equipment for continuous stock infeed and with various outfeed options, including sorting of cut pieces.

kasto pipe cutting

The automatic, high performance circular saw, KASTOgripspeed C 10.

The high performance machine is designed to process materials up to a tensile strength of 1,400 N/mm². Tungsten carbide tipped saw blades of 360 mm diameter and either 2.5 or 2 mm thick minimise the kerf and hence the amount of metal lost as swarf. For some materials, coated or cermet blades are used.

All such blades have the additional advantage that thin or thin-walled materials can be cut safely and efficiently, expanding the range of applications for which the KASTOgripspeed C10 is suitable. Particularly helpful is infinitely adjustable workpiece clamping with a force of 2 to 12.5 kN for safely securing thin-walled tubes and profiles.

Cutting range of the saw is from 15 to 100 mm diameter for rounds or up to 80 mm for square stock. The smallest cut-piece length is 8 mm, while remnant length is only 65 mm. Material feed stroke is 500 mm, or up to 9,999 mm with multiple feed.

Saw drive power is high at 11 kW to ensure efficient cutting of all type of material. Infeed speed ranges from 10 to 4,000 mm/min and is infinitely variable. The same is true for blade speed, which is adjustable from 17 to 175 m/min. Contributing to short idle time is 10 m/min rapid lift of the saw blade at the end of each cutting cycle.

To maximise productivity, continuous material infeed and outfeed is needed. KASTO offers a wide range of roller conveyors and inclined magazines for bar lengths up to 12 metres. As an alternative to inclined magazines, loaders are available for bundles up to a maximum of 5 tonnes. There are also flat and universal magazines for rectangular and profile materials or for fully automatic processing of cutting orders of small to medium batch sizes.

Several possibilities are available for the outfeed side, including conveyors and various types of automated sorting systems.

Automated Robot Bending Drilling Cell


Global leader in the design, manufacture and supply of the world's finest tube bending and endforming technologies, AddisonMckee of Lebanon, USA; Brantford, Canada and Bamber Bridge, UK has recently installed an automated cell into a facility in the north of England.

One of the world’s largest international groups dedicated to the design, development and manufacture of metal components and structural systems for the automotive industry. Whilst AddisonMcKee’s unrivalled experience of CNC bending and forming technology made the company’s appointment to supply a fully integrated system a natural one, it was recently completed on time to the customer’s full satisfaction.


Two components were presented to AddisonMckee to process, one required only bending and drilling, but to be produced by a fully automated solution; the other component only needed forming and production was to be manually controlled. (To be automated at a later date.)


The bending cell incorporated a bunker system fed by pallets of cut 34mm diameter tubes, which were unloaded magnetically and processed within a buffer system, to a pick-up point were the tube was seam detected and presented ready for an ABB robot to collect. The robot with a double gripper held the new tube until the eB80bending machine had completed two symmetrical 1 x D bend on bend applications; it then removed the bent tube and inserted the new tube, and the bending process recommenced. The bent tube is then transferred by the robot to a combined inspection gauge and drilling fixture, if the component is deemed to be incorrect it is transferred to a reject chute; otherwise two holes are drilled and the component is transferred to a finished part stillage, which is mounted on a turntable system. When the stillage is full the turntable presents an empty stillage ready for the process to work continuously. Within any automated system, safety and process fault diagnosis are of paramount importance. AddisonMckee worked with and were assisted by Premier Automation to engineer a fully integrated robotic system that met all the customer’s logistics and health and safety requirements.

addison pipe


The component to be formed was a straight 50mm diameter tube that required three AddisonMckee machines to form both ends and trim to length. One end required a flat to be produced by a two hit 70RF machine and the other end required a 70SRF (selectable ram form). The SRF machine used three hits to produce an offset reduction to a size that allowed the 34mm bent tube to be inserted on the final welded assembly. After forming the resultant end deformation was trimmed to the correct length with an FM70TTPN (tube trim with pre-notch).

Southeast Asia: Gateway to a Single Market & Production Base in 2015

Southeast Asia remains resilient amidst persistent global economic uncertainty, projecting an average annual growth rate of 5.5% over the next five years to 2017. This signals that trade fairs continue to fulfil the industries’ needs as an international business conduit into the region. The region is increasingly becoming a manufacturing and industrial hub for many global companies seeking to locate and keep in touch with available business opportunities.

According to Global Industry Analysts, the global market for seamless pipes and tubes is projected to reach 113.8 million tonnes by 2018. In addition, the global market for spiral welded pipes and tubes is projected to reach 24.6 million tonnes by 2018, driven by economic recovery, increase in activity in the energy sector and growing pipeline construction projects. Industry reports indicate that the Asia-Pacific region represents the largest market worldwide, driven primarily by increased use in transporting natural gas. Similarly, business opportunities in the wire and cable industries are estimated to contribute approximately 3% of the world’s production of wire and cable.

Against this dynamic backdrop, Mr Gernot Ringling, Managing Director of Messe Düsseldorf Asia comments,“wire and Tube Southeast ASIA is taking place at a critical time for the wire, cable, tube and pipe industries both in the region and globally. Companies scanning the region for market opportunities to diversify products, markets and suppliers will find wire and Tube Southeast Asia the ideal platform for lucractive business exchange and networking opportunities.”

According to Mr Ringling, this year’s trade fairs will see a comprehensive display of products and services aimed particularly at enhancing productivity and operations, as well as cost-effective solutions. “In response to this emphasis, exhibitors will focus on innovation, from the latest processes, systems, services and products to meet supplier demands for productivity and efficiency gains. Trade visitors can also expect to see more machinery and equipment at this year’s trade fairs.”
