A unique manufacturing range which allows for the largest dimensions: up to 660mm outside diameters, wall thicknesses up to 65mm, and inner volumes up to 3,000 liters (fit for pressure up to 1,000 bar) are feasible.
Customer support to optimize their designs to adjust to the needs of their projects and to innovate together for safe and efficient refueling stations.
Our Role in Hydrogen
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.
