Multiphysics Coupling Analysis and Failure Evaluation of Hydrogen-Blended Pipelines with Inclusions and Cracks in Weld Seams

Abstract

AbstractHydrogen, which is a pivotal enabler for the clean energy transition, poses a significant challenge—hydrogen-induced cracking (HIC)—in weld zones during cotransport with natural gas. This study focused on determining the failure mechanisms of X80 ...
