Cause analysis of hydrogen induced crack of LSAW steel pipe
LSAW steel pipes, subjected to varying conditions and environments over time, may experience damage due to intrinsic defects and changing stress factors. One of the most critical forms of damage is hydrogen-induced cracking (HIC). This occurs when welded steel pipes, containing hydrogen, crack under the influence of applied or residual stress. Hydrogen-induced cracking is caused by the diffusion of hydrogen into the metal matrix, where it either forms a solid solution or metal hydrides, leading to brittle fractures. This phenomenon poses a significant risk to the structural integrity of steel pipes.
