    • Abstract
  • Several holes were found in wall thickness test on a L245 steel oil pipeline. Causes of pipeline perforation were analyzed by means of wall thickness measurement, corrosion products analysis, transmission medium composition analysis and chemical composition analysis, mechanical property test, morphology analysis of pipeline. The results show that the corrosion perforation was caused by local corrosion in pipeline, and the synergistic effect of HCO3- and Cl- in transmission medium was the main cause of local corrosion.
