AC corrosion interference of buried long distance pipeline

Abstract

The interference law and calculation model of AC transmission lines and other AC facilities on buried long distance pipeline are briefly described. The main influence law of AC current on the passivation behavior of pipeline steel materials is summarized. The research progress on the mechanism and evaluation criteria of AC corrosion of pipeline under cathodic protection is systematically described. The main viewpoints and influencing factors of the mechanism model of ac interference corrosion are summarized, and the main problems of ac interference technology are summarized
