| Abstract: | The combined protection mode of anticorrosive coating and cathodic protection is usually used in long-distance buried pipeline. According to the corrosion control work practices of Sichuan to Eastern China Gas Transmission Pipeline and others,the common problems found in ECDA evaluation and daily maintenance work conducted for many years are deeply analyzed,and several kinds of common factors that affect the operational effectiveness of cathodic protection systemare summarizedwith respect of cathodic protection station,line,valve chamber and so on. |
