Application of Reference Tube Test Method in Long-distance Natural Gas Pipeline Cathodic Protection
Pipeline cathodic protection has a crucial impact on the safe operation of pipelines.Combined with the research on the principle and measurement method of cathodic protection pilot film method,and through the test data of a Shanxi coalbed methane pipeline forced current cathodic protection using the test film method and the reference tube test method,it is concluded that the reference tube test method can effectively reduce the impact of IR drop on the cathodic protection potential,so as to achieve a real and reliable effectiveness evaluation results.
