A number of CPW manufactured HFW and SAWL pipes were tested for fracture toughness properties in high pressure 100% hydrogen environment. All tests were performed in RINA laboratory, following a developed test procedure based on code ASME B31.12 Option B (qualification of the material threshold stress intensity factor KIH). Testing involved API 5L...

Ductile fracture propagation control in modern high strength steel pipeline for transportation of high pressure natural gas with H2 and CO2 contents: arrest requirements evaluation by numerical tool and full-scale testing verification
One of the most severe accidents which could occur in a gas transmission pipeline involves the linepipe wall failure and subsequent fracture initiation, which may evolve in a long running fracture propagation if the material toughness properties are not adequate. The most acknowledged approach for ductile fracture propagation assessment is the...
