Hydrogen is regarded as a central solution to the global strategy to achieve a net zero future. To address climate change
In support of these actions,
Pressurized pipelines are considered a relevant solution for transporting molecular energy from the point of production or storage to the point of consumption. Tenaris Pipeline Technology Senior Director and Chairman of the DNV H2PIPE joint industry project on hydrogen pipelines,
In fact, hydrogen atoms can easily diffuse into the metal's crystalline lattice due to their small size. The interaction with the metal's microstructure can eventually result in the degradation of the metal's mechanical properties, mainly involving a loss in mechanical ductility, reduced fracture toughness and loss of fatigue resistance. Purity, temperature, and pressure can affect the severity of the embrittlement. Thus, it is fundamental to determine how new and existing pipeline materials will react to the different compositions, pressures, and temperatures these pipelines will operate under.
'The experimental activity we carried out ... demonstrates the potential of THera solutions for hydrogen pipeline transportation of up to 200 bar with an extra safety margin.'
'The experimental activity we carried out to qualify seamless and UOE LSAW pipes of up to grades X70, according to ASME B31.12 requirements, demonstrates the potential of THera solutions for hydrogen pipeline transportation of up to 200 bar with an extra safety margin,' highlights Darcis.
