Transportation of hydrogen in pipelines

ROSEN Group is expanding its existing material testing capabilities and dedicating a separate section to the topic of hydrogen. Hydrogen can have an adverse effect on the fracture and fatigue properties of steel. The magnitude of the effect can vary, depending on steel grade and microstructure, concentration of hydrogen, and other factors.

Therefore, integrity assessments need to be based on the material properties in hydrogen, which are usually not known in case of existing lines and must be assessed as part of the process of (re)purposing the lines for hydrogen transportation. Guidance on the design of hydrogen pipelines is given in ASME B31.12, including fracture toughness testing.
