OD ORBITAL CUTTING & BEVELING MACHINES

50 years of experience and technical expertise worldwide

TT series machines ensure perfect cuts and bevels for maximum efficiency. Wherever the priority is to minimize installation downtime and maximize equipment runtime, you will find PROTEM TT machines.

TT series machines are a perfect example of PROTEM’s 50 years of knowledge and expertise in providing job oriented machining solutions.

2019 09 26 092118

TTNG

The tube cutting machines of the TTNG series are built to cut and bevel tubes up to 3.937” (100mm) thick (larger upon request) in the field. Their low clearance design of rotating parts is highly appreciated by customers in all industries such as Nuclear, Oil and Gas and Chemical.

Options for counterboring jobs, cam-copying operations and wheel cutting are possible within the wide range of diameters covered by each model in the TTNG series. The splitframe configuration opens in two half-shells joined together with a hinge. Clamping is ensured by independent adjustable jaws for easy in place set-up. The completely enclosed drive gears and tool holders provide an increased operator safety.

2019 09 26 092144

TTLW

If the TTNG’s low clearance is not enough for you, TTLW machines are the ones you need! These machines are the light weight version of the rugged TTNG. Because of their narrow and lightweight body design, they are the ideal solution for use in confined areas.

TTSNG

The TTSNG version are designed for machining small diameter tubes and pipes. They are built in the same manner as the TTNG machines which allow accurate cutting and/or beveling of tubes and pipes from 0.406” (10.3mm) up to 10.751” (273.1mm) OD.

TTSRD

The collet clamping system of the TTSRD series allows for quick set-up and an easy concentricity adjustment. This clamping method is particularly suited for small wall thicknesses in order to avoid tube distortion in case of poor machine set-up. These machines have the lowest clearance of the range.

2019 09 26 092209

Main advantages:

  • V track and rollers: The V shape design compensates for axial and radial forces to ensure maximum precision and less wear.
  • Aluminium body: Lightweight and durable for limitless machining jobs!
  • Splitframe design with hinge: Easier to set up on continuous or long length pipes.
  • Fully enclosed tool holder design: Protects the feed system from chips and prevents damage during machining.
  • Sliding tool holders: Easier and faster to set up.
  • Machine design permits cutting and beveling operation simultaneously, maximizes productivity!
  • Large diameter machines delivered with two standard configuration motors allowing more power for highly demanding jobs.

TT series machines are available in many configurations with standard or special accessories and options. All the devices provided with the TT series machines are built with the knowledge of PROTEM to provide enhanced performance and job specific solutions.

Axial and radial adjustable clamping jaws:

OD tracking tool holder

The OD tracker ensures consistent machining, regardless of the tube’s ovality. Its roller follows the tube’s OD profile and adjusts the position of the tool holder.

Radial Copying carriage

Copying carriage allows the user to machine any geometry of bevel thanks to a cam-following system. This technology of single point machining is particularly suited for heavy wall machining.

Axial copying carriage

It performs special shape machining on the inner or outer diameter.

Counterboring tool holder

Counterboring operations ensure consistent thickness all around the tube by machining the inside diameter. Operations of this type are essential when automatic welding machines are used.

Cutting wheel

The cutting wheel accessory allows the user to cut the tube without producing chips. The wheel is very useful when cleanliness standards require that no chips can be introduced inside the tube during machining.

Enveloping jaws

Enveloping jaws are designed to clamp the machine onto even the thinnest tubes without any distortion.

Remotely operated machine

TT series machines can be remotely controlled for operations in areas under ionizing radiation or in underwater/subsea environments.

Flat gearbox

Combined with radial positioned drives, this gearbox allows the user to fit the machine in extra low profile spaces.

Milling modules

The tool carriage is replaced by a milling head.

Special configurations and options on request.

In the field of welding, irrespective of the process used, when we examine what is needed for making a top-quality welded joint, preparation is an operation that is often neglected. Normally investments are made on what concerns the welding operation itself, unfortunately without taking account of any prior operations. But, this is a field where judicious investment can be a source of substantial savings.

Even now, certain preparatory operations for welding are done with a grinding wheel or other equally unsuitable tools. Poor preparation will affect the end quality of the weld and lead to rejects, breakage or even leaks in use if defects are not detected in time.

Good preparation for welding is even more important when mechanically welded structures are subject to heavy loads when in use (pressure, heat, mechanical stress, etc.). For example, this is the case in nuclear power or oil and gas industries, two domains where welding needs to be perfect.

Welding preparation equipment that is available on the market can meet practically all users’ requirements, in terms of speed, quality or even size. It also gives companies the possibility of making both rapid and substantial savings.

Splitframe Protem TTNG900Splitframe Protem TTNG900

What economic gains can be identified by setting up a suitable welding preparation system?

Productivity

Gains in time observed when using a suitable welding preparation tool rapidly prove to be considerable.

Preparing for welding on a 10” pipe with 1” thick walls only takes the operator a few minutes (5 at the most) with a PROTEM US80 inside clamping beveller for example, irrespective of the material to be welded (Austenite, Duplex, Inconel, stainless steel, etc.). By using a grinding wheel or other unsuitable tooling, the time taken for preparing for welding will easily be multiplied by 2 or 3 (between 10 and 15 minutes for a far-from-perfect result, which will necessarily be non-repetitive. An operator doing just five welds per day on this type of pipe will need to bevel 10 pipe-ends. If we count a gain in time of 10 minutes per bevelling operation, we will obtain a total saving of 100 minutes per day or 1 hour and 40 minutes. As the average hourly cost of industrial labour is 36.8 Euros, according to Eurostat data, the financial gain is at least 63 Euros per day, which makes a total of 14,238 Euros per year (considering that there were 226 working days in 2018). In this way, gains will rapidly cover initial investments made by the company.

Perhaps, this case study may not be representative of what can be found in all companies, but, even so, by making the calculation, keeping suitable equipment in mind and making a comparison with the savings made over a year, it can be seen very clearly that gains are by no means negligible.

Quality and repeatability

The cost of quality is a sensitive element when looking at welding in detail. Tolerances are increasingly difficult to attain, tests are increasingly precise and specification requirements are increasingly restrictive.  Suitable equipment for preparing welding operations is most certainly a real asset in the search for excellence, expected by contractors. But what financial gain can be found by using this type of machine when it is a matter of quality?

In fact, savings are visible on two levels. Firstly, the number of reject parts will drop naturally by mechanising the task. Tolerances will be maintained more easily and welds will be of higher quality. As a result, the time spent on re-machining reject parts could be devoted to production and make the company’s general productivity increase. A second form of saving can also be made by using this type of equipment. As the process is more reliable and more especially because it provides repetitive good-quality results, the need to check each preparation operation individually is no longer necessary. Statistical checks can be made (1 check every 10 preparation operations, for example, depending on the machine’s reliability) and, as a result, the company’s inspection costs can be drastically reduced (in this case, reduction is close to a factor of 10.

Industrial catastrophe

This paragraph is the direct follow-on to the paragraph on quality. Whenever a poor quality weld succeeds in getting through all its inspections, costs can be calculated in millions or even billions of euros if ever a catastrophe occurs. This is the case in sensitive domains such as nuclear power, refineries or pipelines where the slightest defect is synonymous with catastrophe.

A number of accidents due to poor welding have marked history, such as what occurred at Romeoville, Illinois in the United States in 1984, where the explosion of a poorly welded tank killed 17 people and caused a loss of 200 million Dollars for the company. More recently, in 2004, a gas leak from a pipeline at Ghislenghien in Belgium caused an explosion killing 24 people.

Unfortunately, this type of incident is not all that rare in refineries and on pipelines and the only way of avoiding them is to implement clear welding procedures, based on the use of reliable equipment, irrespective of the level of welding, of preparation and of inspection.

OilGas industry

Safety and user-friendliness

Using a welding preparation machine is also consistent with safety improvement plans. An incorrectly selected machine may prove to be non-ergonomic for the operator, both noisy and dust-producing, both of which are dangers to health. Vibrations are also responsible for a large number of long-term disabilities.  

Choosing a light-weight, easy-to-use machine with practical functions such as torque control will undoubtedly cost money when it is acquired, but the acquisition will immediately reduce risks of injury and time off work, be this at short or at long term. At short term, fatigue will be felt less during the day, which will enable operators to be more efficient. At long term, muscular or bone affections will be less important if suitable equipment is used.

Therefore, safety and user-friendliness can be considered as being an economic benefit for a company that has a global view integrating purchase costs for equipment that contributes very considerably to optimizing its operators’ work conditions.

Splitframe Protem TTNG1200Splitframe Protem TTNG1200

The case of automatic welding

Certain companies would like to invest in orbital welding equipment for gaining time and improving quality when welding pipes and tubes. One of the most frequent mistakes is to neglect preparations for welding.  For automatic orbital welding to work correctly, it must be remembered that there must be no gap whatsoever between the pipes to be welded. Furthermore, ‘J’ shaped bevels are recommended for minimising the need for filling. As a result, geometric tolerances are very complicated to attain Accuracies required can only be attained by using a machine devoted to this type of preparation, a machine that possesses specific options such as a carriage capable of following the pipe’s profile or a counterboring system for maintaining a constant bevel over the pipe’s whole circumference.

Therefore, when investing in automatic welding, it is extremely important to plan for sufficient investments in welding preparation equipment or risk seeing the project fail completely by having automatic welding machines that cannot be used to their full capacity due to shoddily made welding preparation operations.

Pipe Beveling Machine Protem US25Pipe Beveling Machine Protem US25

Conclusion

Therefore, choosing a suitable machine for preparing for welding is an economic asset no matter from what angle this type of investment is considered. It considerably improves productivity and quality. Operator safety is guaranteed and probabilities of a catastrophe resulting from a poor weld are reduced. Lastly, correct preparation for welding is an essential condition for carrying out welding operations, especially automatic welding, in total peace of mind.

Therefore, a company with a long-term view will not merely stop at the cost of the initial investment, but it will look in detail at all the potential savings that this type of machine can offer it.

Portable beveler saddle beveling machine

COMPETENCY, PROFESSIONALISM, QUALITY, SAFETY ARE OUR KEYWORDS

The saddle type tappings allow the perpendicular connection of lateral sections on main pipes. Saddle type tappings are located on collectors and boiler superheaters.

EQUIPMENT THAT POWER PERFORMANCE

2019 04 01 170444The saddle cut is created to produce a T-shaped joint to join the branch pipe to the main pipe. Once the saddle has been cut and properly fit, the field weld can be executed.

These T-shaped joints are mainly done with stationary machines or with Oxy-fuel cutting or grinding machines.

The process sounds simple, but because it’s cut by hand, it’s not always consistent, which requires a lot of grinding to make sure that the profile fits good enough to weld. Typically, though, one pass of grinding and fitting isn’t sufficient.

Using a tool designed for a specific purpose, in this case for beveling saddles, helps to ensure consistency in bevel angles and dimensions, which assists in making welds that are robust and durable.

2019 04 01 170510The portable US25GL Saddle Pipe Beveling machine is a portable, powerful, robust, reliable and versatile machining equipment.

The time to prepare (which can take up to one hour using conventional techniques), is now reduced to minutes thanks to the PROTEM US25GL Saddle Beveling Machine.

Orbital Cutting Machines by PROTEM

Orbital Cutting on Tubes

Tube cutting is a necessary machining operation for the prefabrication, construction, maintenance, repair or removal of damaged parts, caused by corrosion, for example.

2017-03-03 065504

Tubular components are affected by channeled substances that affect the original condition of the tube. Oil, gas or water at high-pressures are abrasive and can alter the corrosion of the tube either chemically and/or mechanically.

When the replacement of the tube is absolutely necessary, the cut is made in upstream and downstream sections of the damaged tube. This maintenance operation can be done on-site and requires the best equipment for a perfect surface quality before performing welding operations.

Orbital Cutting Machines by PROTEM

PROTEM tube cutting and beveling machines are portable machines.
They are light weight, reliable, easy to use and they ensure a perfect weld preparation with no heat affected zones on all types of materials, such as, steel or inox tubes.

CASE STUDY:
Machining a by-pass connection welded on a valve located in a nuclear facility.
The angle and the root face of the connection failed to meet the specifications for the welding operation.
The installation of the valve on a lathe is very complicated.
SERCO has, therefore, been requested to machine this connection directly on-site while respecting the dimensions and the tolerances of the drawing (0.1 mm (.004”).
• ID of the connection: 25 mm (1”).
• OD of the connection: 34 mm (1.339”).
• Tolerance of the root face dimension: 0.1 mm (.004”).

2017-01-30 091700

EQUIPMENT USED:
PROTEM US25 pipe beveling machine with pneumatic drive.
• Mandrel - Ø 18 mm (.709”).
• Specific tool bits.
• Protective collet for the ID of the connection.

2017-01-30 091717

MACHINING TIME:
Assembly of the machine.
+ adjustment of the machine in the connection.
+ machining of the connection.
+ disassembly of the machine.
TOTAL : 20 minutes

2017-01-30 091732

RESULTS:
The customer performed a control with the use of a wax molding.
The result was verified to the tolerances requested.
The use of a portable machine avoided the need to install the valve on a conventional lathe.
The adjustment on a lathe would have required a great deal of time.
In addition, the accuracy would not have been guaranteed.
Only the PROTEM machine was rigid and accurate enough to perform such a machining.

In an industrial setting, a material is never selected by chance. During the design phase, the characteristics of the materials must be carefully studied and determined in order to avoid subsequent complications when in use, and to avoiding incurring unnecessary costs.

This is especially the case when choosing a material to be used in a pipe. This is because some pipes are subjected to considerable mechanical, thermal or chemical stresses, depending on the type of fluid they convey, with pressure and temperature playing a determining role.

The material used to manufacture the pipe has an influence on all the manufacturing operations, including machining. The machinability of the pipe depends directly on the material used to manufacture the pipe, and for each given material, specific precautions must be taken in order to ensure high quality machining.

Machining is a common operation when preparing a piece for welding. The pipe end has to be machined at specific angles so that the weld can penetrate the entire thickness of the pipe material.

2016-10-28 093101

Standard steel

Standard steel pipes are the most commonly used types of pipes owing to their low cost and mechanical properties which make them suitable for a wide range of applications. Steel pipes are resistant to mechanical stresses, durable and formable. This means that they can be used for applications with significant temperature or pressure variations. Standard steel pipes are also very commonly used in situations where impacts or vibrations can affect the pipeline (underneath roads, for example). In addition, steel pipes are fairly easy to manufacture, bend and cut.

Steel pipes are, however, very prone to corrosion if no preventive treatment is applied. Galvanization is a common corrosion-control treatment; this consists of applying a zinc coat to the steel pipe. This coating then oxidizes in the place of the steel which it protects, with the all-important difference, however, being that the zinc oxidizes very slowly.

Low-alloy steel (i.e., with a low carbon level between 0.008% and 2.14%) can be easily machined. When the carbon rate increases, the material properties (such as hardness or mechanical resistance) tend to improve significantly. However, machining steels with a high carbon level is more difficult.

2016-10-28 093208

P91 Steel

P91 steel is an alloy steel with a high chromium (9%) and molybdenum (1%) content. Adding chromium increases the mechanical resistance at high temperatures as well as corrosion resistance, and adding molybdenum improves creep resistance. Small amounts of nickel and manganese are added to enhance the overall hardness of the material. P91 steel is very sensitive to changes in its microstructure that can occur during excessive heating. These microstructure variations tend to weaken the material. This is why cold machining is often preferred for cutting this material.

P91 was initially developed for the manufacturing of pipelines in conventional or nuclear thermal power plants, where the steam leaves the superheater of a boiler in a modern conventional/thermal plant at a temperature of between 570°C to 600°C and a pressure of 170 bars to 230 bars. This means that the final stages of the superheater and the pipelines delivering the turbine steam must be able to withstand these extreme conditions. In such a case, the high mechanical resistance of P91 and its fatigue strength makes it the right choice.

By using P91 in such circumstances, the engineers were able to reduce the thickness of the pipelines while simultaneously increasing the operating temperature, all of which enhances the overall thermodynamic efficiency of a power plant.

The high mechanical resistance of P91 steel means, however, that machining is difficult. Thus, the tool bits should be changed regularly to ensure their sharpness, and the cutting speeds should be kept slow. The feed rate can also be adjusted to increase the machining speed.

Duplex steel

A Duplex stainless steel consists of stainless chromium steel with nickel added. The matrix contains both ferrite and austenite, hence the name Duplex. This alloy was designed to provide corrosion resistance and tensile strength. Duplex steel pipes are very commonly used in gas and petroleum offshore platforms where the pipelines are subjected to intense pressures and corrosive elements (salt water). Duplex steel tubes can also be found in industries with chlorinated products and acids, such as in the chemical or pharmaceutical industries. In recent years, more strongly alloyed Duplex steels have emerged under the name of Super-Duplex or Hyper-Duplex.

Duplex steel pipes are relatively difficult to machine due to their tensile strength and high yield strength. This can lead to very high cutting temperatures and to plastic deformation of the pipe. In any case, the tooling and clamping must be sufficiently rigid and stable in order to machine a Duplex steel pipe.

2016-10-28 093412

 

Stainless steels

Just like standard steels, stainless steels are comprised of iron and carbon, to which chromium has been added. Upon exceeding a certain proportion of chromium (10.5%), a chromium oxide layer is formed on the steel surface. This so-called “passive layer” is chemically inert, corrosion resistant and stable.

Other elements can be added to improve the mechanical strength (nickel) or high-temperature performance (molybdenum, titanium, vanadium, tungsten).

Although more expensive than standard steel pipes, stainless steel pipes are widely used in many industries (chemical, petroleum, pharmaceutical, food, aerospace, shipbuilding, etc.).

Their popularity stems from their corrosion resistance and chemical stability which make stainless steel piping suitable for fluids that must not be contaminated (pharmaceutical industry, food industry, etc.) and for corrosive fluids (the chemical industry, in particular).

The machinability of stainless steel is highly dependent on the proportion of alloying elements. Specifically, a high proportion of chromium, nickel or titanium makes machining more difficult, whereas adding carbon or sulfur facilitates machining.

The cutting edge must be sharp to facilitate chip detachment from the material and reduce the cutting forces.

The cutting tool must be sufficiently well assembled and the machine itself must be sufficiently rigid to support the forces caused by machining; as a rule of thumb, the forces deployed when cutting stainless steel can be more than 50% higher than with standard carbon steel.

2016-10-28 093601

Superalloys

Most of the superalloys used to manufacture pipes belong to the range of nickel-based superalloys. This range includes Inconel and Austenite, named after the alloy manufacturer.

Therefore, the alloy base is nickel which can be alloyed with chromium, iron, titanium or aluminum. These alloys have the same advantages as stainless steels, but to a greater extent. Specifically, their heat resistance is higher (about 900°C) as is their corrosion resistance (corrosion in chlorine ion solutions, ultrapure water and caustic mediums). They are also much more expensive than standard alloys, but this is justified for applications where operator safety is an essential criterion.

Pipes made from nickel-based superalloys are used in aerospace (in combustion chambers, for example), the chemical industry (due to their corrosion resistance), nuclear engineering, and, to a lesser extent, in the food industry.

Superalloys are considered very difficult to machine. This can be attributed to several factors. First, one must bear in mind that 70% of the heat is returned directly to the cutting tool (as opposed to 15% for standard steel, for example). Therefore, it is essential to keep the cutting-edge cooled during machining. The second complication is the hardness of the material; in fact, the lifetime of a cutting tool used to machine a superalloy can be reduced to just a few minutes if the tool does not have the necessary power, or if the cutting speeds and tools are not suitable.

2016-10-28 093648

Titanium

Titanium is an extremely interesting metal for the industry. Titanium can be used to manufacture pipes which are light and yet highly resistant to corrosion and able to withstand very high temperatures (600°C). Its mechanical properties (resistance, fatigue and ductility) are also appreciated. Titanium is, however, expensive and this limits its use to specific applications. In general, one finds titanium in the aerospace sector where its low density combined with its attractive mechanical properties make it an essential material.

Since the thermal conductivity of titanium is very low (about ten times lower than steel), the heat dissipation during machining is relatively poor. Therefore, the cutting edge needs to be properly cooled to avoid machining defects.

Sharp tools should be used to facilitate chip detachment from the material, and thus reduce the cutting force.

Machining is even more difficult in the case of treated titanium (e.g., treatment by precipitation hardening, presence of chromium coating or alloying).

2016-10-28 093733

Aluminum

Aluminum is very widely used in the industry. Aluminum pipes are inexpensive, easy to form and assemble. They are also light and corrosion-resistant, making them a natural choice in the aeronautics, transport and construction sectors. Aluminum pipes are also used to build compressed-air pipelines.

Aluminum pipes have a very low level of hardness, and are therefore relatively easy to machine. However, the malleability of aluminum can cause problems (shavings can lead to machine jamming, for example). In this case, the best response is to increase the cutting speed, the depth of the pass and the feeding speed. There is also a risk of aluminum pipes being deformed during machining if the machine tool, and in particular, the clamping jaws, are not correctly chosen.

The high thermal conductivity of aluminum allows for good heat dissipation. Thus, the cutting speed can be increased without reducing the lifetime of the tools.

In an industrial setting, a material is never selected by chance. During the design phase, the characteristics of the materials must be carefully studied and determined in order to avoid subsequent complications when in use, and to avoiding incurring unnecessary costs.

This is especially the case when choosing a material to be used in a pipe. This is because some pipes are subjected to considerable mechanical, thermal or chemical stresses, depending on the type of fluid they convey, with pressure and temperature playing a determining role.

The material used to manufacture the pipe has an influence on all the manufacturing operations, including machining. The machinability of the pipe depends directly on the material used to manufacture the pipe, and for each given material, specific precautions must be taken in order to ensure high quality machining.

Machining is a common operation when preparing a piece for welding. The pipe end has to be machined at specific angles so that the weld can penetrate the entire thickness of the pipe material.

2016-05-30 085341

Standard steel

Standard steel pipes are the most commonly used types of pipes owing to their low cost and mechanical properties which make them suitable for a wide range of applications. Steel pipes are resistant to mechanical stresses, durable and formable. This means that they can be used for applications with significant temperature or pressure variations. Standard steel pipes are also very commonly used in situations where impacts or vibrations can affect the pipeline (underneath roads, for example). In addition, steel pipes are fairly easy to manufacture, bend and cut.

Steel pipes are, however, very prone to corrosion if no preventive treatment is applied. Galvanization is a common corrosion-control treatment; this consists of applying a zinc coat to the steel pipe. This coating then oxidizes in the place of the steel which it protects, with the all-important difference, however, being that the zinc oxidizes very slowly.

Low-alloy steel (i.e., with a low carbon level between 0.008% and 2.14%) can be easily machined. When the carbon rate increases, the material properties (such as hardness or mechanical resistance) tend to improve significantly. However, machining steels with a high carbon level is more difficult.

2016-05-30 085439

P91 Steel

P91 steel is an alloy steel with a high chromium (9%) and molybdenum (1%) content. Adding chromium increases the mechanical resistance at high temperatures as well as corrosion resistance, and adding molybdenum improves creep resistance. Small amounts of nickel and manganese are added to enhance the overall hardness of the material. P91 steel is very sensitive to changes in its microstructure that can occur during excessive heating. These microstructure variations tend to weaken the material. This is why cold machining is often preferred for cutting this material.

P91 was initially developed for the manufacturing of pipelines in conventional or nuclear thermal power plants, where the steam leaves the superheater of a boiler in a modern conventional/thermal plant at a temperature of between 570°C to 600°C and a pressure of 170 bars to 230 bars. This means that the final stages of the superheater and the pipelines delivering the turbine steam must be able to withstand these extreme conditions. In such a case, the high mechanical resistance of P91 and its fatigue strength makes it the right choice.

By using P91 in such circumstances, the engineers were able to reduce the thickness of the pipelines while simultaneously increasing the operating temperature, all of which enhances the overall thermodynamic efficiency of a power plant.

TU TE series from Serco

2016-04-07 063844The TU TE series of machines is like a portable CNC machine with a numerical center. This machine allows standard operations such as facing, boring, beveling, and can also create landings and threads.

There is already opportunity for the standard operations, but these are improved with the new TU TE series. The machine can perform facing operations, but also, an improvement on this function, the cutting speed is not dependent on diameter. Boring is also improved because there is no minimum speed due to the brushless motor.

While serrated surfaces are possible on the standard machine, this machine has more possibilities. Because of the programming capabilities, the space between serrations can be variable and creating concentric circles is much faster. Beveling is a function of the standard machine, but also improved with the new series, with a longer stroke depth and unlimited possibilities of beveling angle.

At first, the goal of the machine was to create a way to thread with a single tool bit instead of a tap, but this machine has many more capabilities. A tap can be easily broken, which can cause huge problems, especially with large or expensive equipment. With single point machining, the tool can be easily changed if broken, with almost no lost time.

2016-04-07 063907Another advantage of the new series is the ease of switching from manual to programmed mode. The manual functions are still important, but when programming is needed, it just takes the push of a button. By writing a program for the machine, any shape can be created.

These machines have high rigidity and precision, both necessary for threading. There cannot be any play in the machine at all during the threading process because the tool must pass at the same precise location each time to create perfect threads.

2016-04-07 063919Another improvement is the ability to control the machine remotely – although the controls are attached by a cord, the control box can be moved away from the machine which is a huge advantage when radiation exposure is possible. Programming can also be done remotely as long as the machine is connected to the internet.

This machine has a similar application to a lathe or grinder, but is portable and lightweight and has a brushless motor, so it can go anywhere and the motor has no risk of spark.

Because of this new technology, we are learning more every day and stepping up in innovation.

The TTNG Series is the premier choice for perfect welding preparations.  Over decades our machines have undergone advanced development and have consistently delivered reliable technology.

Each TTNG meets the demand for high accuracy in today‘s welding applications.  They are designed to machine virtually any wall thickness, perform superbly on heavy wall tubes and pipes, and have been applied successfully on materials with high hardness. TTNG cutting and beveling machines are versatile, dependable, feature powerful drive motors, and a durable yet light weight design. Machines you can trust!

2015-07-22 094919

The machines are mounted to pipe by opening the two half-shells connected with a single hinge, greatly simplifying the mounting process.

Concentric alignment is achieved by independently adjustable clamping jaws; perpendicularity is adjusted simultaneously. Additional clamping screws are tightened to distribute and bear the axial forces. Tool carriages with covered bearings and gears protect against the ingress of chips and debris; this ensures long machine life.

Two tool carriages equipped with the tool bits can perform a simple cut or will cut and bevel in one operation. Two incremental feed speeds can be selected. The machines can be operated in all rotated positions.

A wide range of modular options extends the capabilities of the TTNG machines:
•    Carriages with double stroke length
•    OD-Tracking carriages to follow the ovality of the tubes
•    Counterboring carriages to perfectly round the inside diameter
•    Copying carriages to perform j-bevels or compound bevels on heavy wall pipes
•    Cutting wheels for chip free cutting operations
•    Enveloping jaws for thin wall thicknesses
•    Remote control for hazardous operations such as: radiation, deep waters, and others
•    Axial copying carriage to perform profile matching on the outside diameter
•    Flat gearbox and radial positioned drive with no exposed parts on the backside
•    Milling modules instead of the tool carriages for special applications

Feed: Automatic with clutch
Motorization: Pneumatic or hydraulic  Electric drives upon request

Some tubular components, flanges, valves, high pressure valves, sealing valves, valves seats, conical seats and others require preventive maintenance but also sometimes curative maintenance.
Some of those components are light, easy to disassemble and consequently easy to transport.
Some maintenance or repair works can be easily scheduled.

But...

2014-08-14 103407 protemSome maintenance or repair works can suppose that some parts or components will have to be put on a workshop fixed machine which will be mobilized for those works. This will mean that in most cases, the following actions will have to be done:

- First, the part(s) will  have to be disassembled.
- They will have to be packed for the shipment.
- A specific shipment will have to be organized.
- If the case arises, the parts will be stored awaiting the availibity of a lathe, or of a milling machine or other appriopriate workshop fixed machine.
- Several persons, including material handlers, will also be mobilized.
- A return shipment will have to be organized.
- Strict and complicated handlings will have to be performed in order to avoid damaging the parts during their shipment and during their re-assembly on site.
- Any other actions which will be necessary (particularly, if the components that need a re-machining, a maintenance or a repair, have been subject to hazardous environment - ionizing radiation for example...).

An on site machining, performed by machining professionals, with portable machining equipment adapted to the need, represent then an undeniable better solution:
- the operator is travelling on site
- the operator performs the job directly on the part to machine.
