Abstract

The invention discloses a pipeline residual life prediction method and system based on hydrogen diffusion dynamics. The method comprises the steps: acquiring basic data of a pipeline to be subjected to life prediction; inputting the basic data of the pipeline to be subjected to life prediction into the screened pipeline crack growth rate calculation model, and outputting the pipeline crack growthrate; and predicting the residual life of the pipeline according to the initial crack size and the pipeline crack growth rate.

Description

technical field [0001] The present disclosure relates to the technical field of pipe life prediction, in particular to a method and system for predicting the remaining life of a pipe based on hydrogen diffusion dynamics. Background technique [0002] The statements in this section merely mention background art related to the present disclosure and do not necessarily constitute prior art. [0003] Traditional research on hydrogen embrittlement can only qualitatively discuss the embrittlement mechanism of materials caused by hydrogen atoms, mainly including HELP (Hydrogen Enhanced Local Plasticity), HEDE (Hydrogen Enhanced Decohesion) and hydrogen bubble theory (caused by the accumulation of hydrogen atoms in defects to generate hydrogen gas). local stress enhancement) of these theories. [0004] The HELP theory emphasizes that hydrogen atoms can promote the movement of dislocations at the crack tip, thereby greatly improving the local plasticity. At first glance, this view ...
