Affects of Cathodic Protection Potential on Cathodic Disbanding of 3-layer PE Pipeline

GE Ai-tian

Abstract

There are standards and regulations set for minimum Cathodic protection criterion,without maximum one in domestic and abroad.The theory of cathodic disbonding is introduced in this paper,and the condition of cathodic disbonding is stated,the relationship between the cathodic protection potential and the cathodic disbonding diameter is affirmed by experiments,some advices on set of cathodic protection potential is put forward in the end of the paper.
