Reasons Analysis on Corrosion Perforation of L245 Pipeline from Interior Wall

Abstract:

The leakage accident of corrosion perforation occurred in the L245 oil pipeline. After pipe replacement,the defects were analyzed by means of macro analysis, corrosion product analysis, medium composition analysis, chemical composition analysis, mechanical property test and SEM. The results showed that the corrosion perforation was caused by local corrosion, and the synergistic effect of HCO₃^- and Cl^- in transportation medium was the main cause of local corrosion.
