摘要
Abstract
Leakage was found from a valve of one hydrogen pipeline because of the fracture of the stud bolt of the valve .Based on material analysis ,fracture morphology analysis and other chemical or physical testing ,it is considered that stress corrosion cracking ( SCC ) is responsible for the fracture of the bolt . Then the influence of three factors of material ,stress and corrosive environment on the SCC is analyzed re-spectively in details .Improper selection of the material is identified as the root cause of the fracture of the bolt.At last,suggestions are given for how to choose the bolt material and how to examine and manage the pipe .关键词
