Etude de la nocivité d'un défaut de type éraflure sur une conduite destinée au transport de gaz naturel soumise à une pression d'hydrogène

Abstract : Currently major research effort is focused on the use of hydrogen as a new energy vector both in Europe and the US. An obvious pragmatic solution for transporting hydrogen, which will be necessary to make the European hydrogen economy feasible, could be to transport a mixture of natural gas and hydrogen in the actual existing natural gas pipe network. Within the European project NATURALHY, 39 European partners have combined their efforts to assess the effects of the presence of hydrogen on the existing gas network. This study is in this context. It focuses on the mechanical properties decreasing of a steel API 5L X52 by hydrogen, obtained in a gas and an electrolytic solution. This effect is quantified by a high number of different tests (burst, fracture, crack propagation, fatigue lifetime). The hydrogen consequence on notch like defect, is analyzed by coupling a deterministic Modified Notch Failure Assessment Diagram (MNFAD) and SINTAP procedure.Study of the harmfulness of a defect like a scratch on a pipeline used to carry natural gas under a pressure of hydrogen
