Measurement of the Effect of Magnetism on Hydrogen Cracking Susceptibility of Pipeline Steels - Joint Industry Project. Colorado School of Mines - Final Report

摘要

The behavior of thick high-strength pipeline steels was assessed under simulated field conditions including assessment of (1) steel strength, (2) stresses due to cold work, surface damage, and fluid pressure, (3) hydrogen activity related to cathodic protection, soil conditions, and fluids carried in the pipe, (4) temperature, and (5) remanent magnetism in steels after pigging with magnetic inline inspection tools. The values for (1)-(5) will be varied to simulate field conditions. This project aims to measure electrochemical corrosion and hydrogen induced cracking susceptibility of pipeline steel under simulated conditions in a quantitative manner.
