The mechanism and characteristics of AC interference corrosion and the unfavorable effects on buried oil and gas pipelines are analyzed. A new classification standard and advanced AC interference test methods for the risk of AC interference in buried pipelines are introduced. The current research status of cathodic protection standards when interference and put forward their own opinions.At the same time, the domestic and foreign research on new techniques and methods of interferential corrosion protection of buried pipelines are summarized.According to the interference of domestic and international exchange interference corrosion and protection The latest research progress, combined with their own experimental results, through comparative analysis, in the exchange of interference evaluation, testing and protection made recommendations
