Partnering on the hydrogen infrastructure build

Already a rapidly developing sector, hydrogen transport via pipeline can benefit from Vallourec’s expertise in pipe and tube metallurgy in relation to hydrogen.

  • A comprehensive line pipe product and services offer adapted to hydrogen transmission including seamless line pipe for: on and offshore use with fatigue-sensitive applications; high-pressure operations; corrosive environments; ultra-deep and sour service environments with a focus on combatting hydrogen embrittlement.


  • Serimax welding and field joint coating services.


  • Associated services such as external anti-corrosion and thermal insulation coating, CRA lined pipe, bends, welding and multi-jointing.


  • Accompanying customers in repurposing their pipes for a new fluid and assessing the best solutions to support them in this ambition.


  • Expertise and availability to act as a potential supplier for newbuilds.
What Is Hydrogen?


Hydrogen’s physical properties make the development of robust infrastructure complex. Vallourec’s materials expertise is proving invaluable in developing the necessary solutions.

Important physical properties of hydrogen

High energy
Hydrogen offers 3x the energy of gasoline per unit of mass, making it an attractive fuel source.
Low density
Hydrogen is the lightest element (1/10 of natural gas), so larger volumes must be moved to meet identical energy demand. Gaseous hydrogen needs to be stored and transported at high pressures, up to 1,000 bar; Vallourec has a strong track record with such high pressures.
Higher velocity for pipeline transportation
Hydrogen is flowing about 3 times faster than natural gas when transported in pipelines; when combined with lower density, this means that the energy flow in a pipeline is about 80% compared to a natural gas pipeline in similar conditions.
Highly flammable
Hydrogen has high flame velocity (8x methane) and ignition range (6x wider than methane). Gas tightness and reliability of solutions, a key expertise and commitment of Vallourec, will be essential.


All these technical challenges will certainly find appropriate responses. Vallourec will contribute to these, so that the required infrastructure can be safely developed. In this way, the full potential of hydrogen as a low-carbon technology can be unleashed.

News – Large-scale hydrogen for a cleaner tomorrow

Dec. 2020 | by Vincent Designolle
From solar and wind to biomass, the number of cleaner alternatives to fossil fuels has exploded in recent years. But one clearly stands out from the pack: hydrogen. Already well established in industrial uses, hydrogen is now angling to conquer hard-to-decarbonize sectors like heavy transport and energy-intensive industries. To ensure success, infrastructure at a large scale will be needed to support hydrogen’s growth—a gargantuan undertaking that Vallourec is well placed to support.

Case Study
Hydrogen is set to play a key role in the energy transition acting as a low-emission energy carrier for various applications. However, hydrogen is known to affect mechanical properties of some materials, a phenomenon named hydrogen embrittlement. To ensure safe transport and storage of compressed gaseous hydrogen, steels must be proven resistant to such environments. Vallourec has successfully qualified the fracture toughness resistance of a selection of steel grades for OCTG pipes, line pipes and pressure vessels in the presence of pure H2 gas. Thanks to its material expertise, Vallourec succeeded in testing higher strength steels that, for certain applications, enable thinner walls, lighter solutions, and reduced resource consumption to its customers.
