Simulated Feeding Test of Impressed Current Catholic Protection for a Natural Gas Pipeline

In Fujian LNG Xiang′an- Zhangzhou pipeline, the length of pipe under effective cathodic protection condition is only 16~17 km. There is still more than 40 km pipeline under insufficient protection condition. Simulated cathodic protection feeding test was conducted at Xiamen delivery station. This paper introduces the experimental ideas and process of implementation, analyzes the testing results, and puts forward some measures to solve this problem.
