ArcelorMittal gears up to support vital new energy pipelines

ArcelorMittal has provided steels for the global oil and gas pipeline industry for more than 30 years. In the past five years alone, we have supplied more than two million tonnes of steel to the industry. ArcelorMittal’s success in this highly demanding sector is largely due to our ability to consistently produce quality steels with the required properties, time and time again.

Steel quality is a critical issue for oil and gas pipelines which are subject to very high operating pressures, atmospheric conditions along their route, and corrosion from the gas and liquids they carry. Any failure in the steel can lead to catastrophic consequences. Ensuring this does not occur requires special attention at every stage of the steelmaking process.

The combined TANAP and TAP pipelines will stretch over 2,800 km and bring natural gas to Europe from the Caspian Sea.

Fine control

It starts during steel production where the chemistry of the steel and alloying elements are finely controlled. During slab production, special attention is paid to cleanliness and segregation control – important factors for pipe welding and toughness. In the last step, rolling at the hot strip mill, a reliable thermo-mechanical process is used to guarantee the final properties of the steel.

Thanks to ArcelorMittal’s high-quality steels for energy pipes we have been listed as a qualified supplier for one of the largest oil and gas pipeline projects in the world – the Trans Anatolian Natural Gas Pipeline (TANAP). Together with the Trans Adriatic Pipeline (TAP), TANAP will stretch for 2,800 km from the Caspian Sea to Italy. Construction is due to begin in late 2014.

Each project is unique

Anticipating the future needs of TANAP and other global pipeline projects, ArcelorMittal has optimised our existing X70 heavy gauges and collaborated with the Global R&D centre in Ghent to develop a new X80 grade which is 24 mm thick and guaranteed at temperatures below -20°C.

ArcelorMittal can produce X80 in heavy coils (up to 45 tonnes) and in thicknesses up to 25.4 mm. We apply the strictest safety standards in order to handle these heavy gauge coils.

Recognising that each pipeline project has its own unique requirements, ArcelorMittal has a make-to-order strategy. Steels are produced according to the customer’s technical requirements for each project.

Coil weights and product dimensions are chosen to optimise productivity.

ArcelorMittal produces hot rolled coils for energy pipes at three locations in Europe: Bremen (Germany), Fos-sur-Mer (France), and Krakow (Poland). Heavy plates for oil and gas pipes are produced in Gijón (Spain) and Galati (Romania). Globally ArcelorMittal supplies steels for oil and gas applications from our mills in Brazil, Canada, Mexico, South Africa and the USA.

Last news on Tanap

Denis Parein, Head of Business Development Energy at ArcelorMittal Europe – Flat Products, explains the massive project to supply hot rolled coil steel to the TANAP project in the TEAS Magazine July 2016.
