Outokumpu stainless steel gives a new look for the New Street station in Birmingham, UK. More than 8 000 bright polished, laser-cut panels of stainless steel, altogether more than 20 000 square meters, will cover the façade of the station. Outokumpu supplies up to 400 tons of stainless steel for the cladding of the building.

140 000 passengers use the Birmingham train station daily, which makes it one of the busiest train stations in the UK. Originally it was built accommodate to less than half that number in the 1960s. Network Rail is now undertaking redevelopment work which will give passengers a concourse with three and a half times more space, more accessible platforms with new escalators and lifts. During the work, the concrete exterior of the building will be cladded in stainless steel. 

Martifer is managing the entire project that started in 2010 in the Birmingham city centre. They requested a very brightly polished stainless steel for the façade of the building. All of the stainless steel in the new New Street station comes from Outokumpu. Tornio produced three-millimeter 316 coils which were then cut to length, bright polished and finished in Sheffield by Outokumpu and its subcontractor, a long-time partner of Outokumpu who was recommended to the customer by Outokumpu. Outokumpu’s plate service centre in Sheffield also advised the station contractors on how to handle stainless steel.

“The stainless steel façade is an integral element of our project to completely transform Birmingham New Street station. We are working in and around an original 1960s structure that has long given a tired and poor impression to the busiest station outside of London and Britain’s second city.  The steel cladding transforms the dated structure into a stunning, 21st century, world class building and puts the station on the map as a landmark in Birmingham, adding to the city's growing reputation for good design. The steel cladding completed so far has already created a buzz around the city and all involved are excited about the future final completion,” says Chris Montgomery, Network Rail Project Director.

“After a careful market analysis and detailed tendering process, Martifer selected Outokumpu due to the high-end characteristics of the product and the confidence instilled in us during the several technical meetings that preceded the order issue. As the extreme complexity of this project is only surpassable through careful management of processes and adequate monitoring of all operations, Outokumpu proved to be the partner we needed for a project of this magnitude and technical requirements. Outokumpu is technically and in Martifer’s opinion the leading expert in stainless steel solutions,” says Francisco Loureiro at Martifer.

The first half of the New Street station has opened up for passengers in April 2013. The station will be completed in 2015.

The new stainless steel works was constructed on a "green field" site near the port of Mobile for ThyssenKrupp Stainless LLC, and sold to Outokumpu at the end of 2012. Siemens received the order to equip the plant in 2008. Liquid steel is produced in an electric arc furnace with a tapping weight of 160 tons. The steel is then further processed in a 180-ton AOD converter and a ladle treatment station. Integrated basic automation and a Level 2 process optimization system ensure that all components of the plant interact optimally. In order to minimize the environmental impact, Siemens installed a dedusting system with pulse-jet filters for the electric arc furnace and the AOD converter.

Siemens supplied the complete, single-strand continuous slab caster for the casting section. The bow-type caster has a casting radius of 9 meters and a straight mold. It is designed to produce slabs ranging in width from 800 to 1900 millimeters and thicknesses from 180 to 240 millimeters. The casting speed is 1.3 meters per minute. The plant produces stainless steels of AISI quality grades 200, 300 and 400 for a wide range of applications. The casting plant features a number of technology packages to assure the internal and external quality of the slabs. These include a mold level control, a breakout detection system, a hydraulic mold oscillator and a system to adjust the width of the slabs. The strand containment is equipped with smart segments. The combination of the Dynacs cooling system with internally cooled I-Star rollers offers maximum flexibility in the secondary cooling. The scope of supply also includes the complete basic and process automation, as well as machines for weighing the slabs.

Siemens was responsible for engineering and supplying the equipment, supervising the installation and commissioning work, and providing the training of the customer’s personnel.

Mobil SHC™ 500 helps steel operators improve energy efficiency
Mobil SHC 500 range of high performance hydraulic oils can help reduce energy consumption of equipment by up to 6.2%

Mobil SHC™ 500 hydraulic oils have been proven to offer maintenance professionals significant energy efficiency benefits in hydraulic equipment.

Compared to standard mineral alternatives, Mobil SHC 500 Series can help reduce hydraulic system’s energy consumption by up to 6.2 percent*, a saving marked by the ExxonMobil ‘Energy Efficiency’ logo on packaging. The Mobil SHC 500 Series are supreme performance hydraulic oils formulated from synthesised, wax-free hydrocarbon base fluids combined with a carefully engineered super- stabilised additive system. They are exceptionally high quality, wide-temperature, shear-stable hydraulic oils with controlled low-temperature pumpability properties and maximised anti-wear protection for high-pressure vane, piston and gear pumps used in steel plants.

The increased hydraulic efficiency potential of Mobil SHC 500 can result in an overall reduction in CO2 emissions, helping reduce the environmental impact of metallurgical operation

 

The increased hydraulic efficiency, impressive system cleanliness and durability offered by the Mobil SHC 500 can help maintenance staff decrease machine maintenance, extend oil drain intervals, and potentially reduce hydraulic system energy consumption by up to 6.2 percent*. Additionally, the increased hydraulic efficiency potential of Mobil SHC 500 can also result in an overall reduction in CO2 emissions, helping reduce the environmental impact of metallurgical operations. In addition, Mobil SHC 500 Series deliver outstanding low and high temperature performance, providing an extra margin of equipment protection above and beyond the capabilities of comparable mineral oil-based products. This benefit resonates with the steel industry that is subject to extremely high operational temperatures and, therefore, demanding sufficient heat-resistance from the lubricants in use. Also, at -400C Mobil SHC 500 is four times thinner than similar viscosity index conventional mineral hydraulic oils**, allowing it to circulate around the hydraulic system faster at start up, ensuring the lubricant is in place to protect machine components.

“Given the high operating temperatures and heavy loads, steel mills are a challenging environment for lubricants to operate in,” said Andrea Jacobsen, Industrial Marketing, Europe, Africa & Middle East, ExxonMobil Lubricants and Petroleum Specialties Company. “The benefits offered by the Mobil SHC 500 series are further proof of how Mobil Industrial Lubricants’ application expertise and portfolio of synthetic products can help steel mills worldwide reduce unscheduled downtime, increase productivity, safety and reduce costs.”

*Energy efficiency relates solely to fluid performance when compared with conventional reference oils of the same viscosity grade in hydraulic applications. The technology used is able to achieve up to 6.2 percent efficiency compared with the reference when tested in a hydraulic system under controlled conditions. Efficiency improvements vary based on operating conditions and application. ** Based on comparative -400C Brookfield, ASTM D2893 test results, between Mobil SHC 525 and Mobil Univis N 46.

New ‘Parker Grade’ 6MO instrumentation tubing

The design of fluid instrumentation systems for use in harsh and corrosive environments  has been boosted by an optimised new grade of 6Mo tubing.

The mechanical characteristics of the new ‘Parker Grade’ 6Mo tubing have been optimised to ensure integrity of connections made using instrumentation compression type fittings from the Instrumentation Products Division of Parker Hannifin – the global leader in motion and control technologies. Parker’s long history in specialpurpose alloy tube fittings has enabled it to build up a wealth of expertise and knowledge about corrosion resistant materials such as 6Mo. The company has played a formative role in the industry  take-up of the alloy, which is now the material of choice for many instrumentation tubing systems on new and refurbished North Sea oil and gas production platforms. Containing at least 6 percent molybdenum, 6Mo alloy is a super-austenitic stainless steel. The material is more resistant to chloride-induced pitting, crevice attack and stress corrosion cracking than standard 300 series or duplex stainless steel, making it ideal for offshore applications demanding durability and reliability in a hostile environment. Parker produces 6Mo versions of various types of instrumentation tube fittings, together with a series of 6Mo tubing clamps, and can also machine instrument valves and manifolds in the material.

Many instrumentation system designers specify two ferrule compression fittings for the assembly of small-bore tubing, with the 6Mo version of Parker’s A-LOK design proving a popular choice for today’s offshore projects. As with all two ferrule fittings, the rear ferrule needs to be harder than the tube it is gripping so that it ‘bites’ into the tube material during assembly helping to create a reliable, pressure-tight seal. Parker hardens the rear ferrule of 6Mo A-LOK fittings using its unique Suparcase process, which provides marketleading corrosion resistance.

However, when ordering instrumentation tubing, customers often simply specify an ASTM standard to their supplier. These standards do not always guarantee an optimum material property for a high integrity tube and fitting combination. The result can be tubing that is harder than necessary, for example, and therefore less than ideal for use with twin ferrule compression fittings.

As part of its ongoing commitment to helping users improve the integrity and corrosion resistance of instrumentation systems, Parker ensures that all tubing stocked by the company and its distributors is fully compatible with its range of fittings. After exhaustive testing and analysis of 6Mo tubing, Parker has defined a stringent specification and tolerances for its manufacture that allows the material’s properties to be controlled very precisely.

By collaborating with its supplier and auditing the company to verify compliance, Parker is able to provide the new Parker Grade 6Mo tubing with mechanical characteristics that are optimally matched to the capability of its 6Mo instrumentation fittings. According to Paul Shaddick, Product Manager for Parker Hannifin’s Instrumentation Products Division, “Extending  the reach of our quality control standards to encompass the manufacturing processes used by our supplier of 6Mo alloy tubing is a major step forward in our product development strategy. Our customers can now obtain all the 6Mo instrumentatio connection technology they need for an offshore project from a single source, secure in the knowledge that the components are compatible. This simplifies component procurement and distribution, helps speed installation, and eliminates  potential leak paths in 6Mo compression fittings.”

Parker Grade 6Mo instrumentation tubing is available in a wide range of imperial and metric sizes up to 1 inch/25 mm OD, and its 6Mo A-LOK two ferrule compression fittings are  suitable for the majority of topside applications involving pressures up to 413 bar/6,000 PSI.
