- Abstract:
- Cathodic protection and outer coating were the necessary measures to prevent corrosion of long-distance pipelines. In this paper, the interactional factors related to the coexist of cathodic protection and outer coating was discussed. Firstly, the influences of pipeline outer coating types, defects and environment on cathodic protection current penetration were introduced. Secondly, the effect of coating peeling, cracks, damage and sulfate-reducing bacteria on cathodic protection performance were summarized. Thirdly, the effects of pipeline steel cathodic protection on coating adhesion, peeling, the resistance and stress corrosion fracture were clarified. Finally, the key issues were pointed out in further studying the interaction between pipeline outer coating and pipeline cathodic protection.
