The potential test pile is installed next to the pipe insulation joint. What is this potential test pile used for?

The potential test pile is an auxiliary equipment specially used for cathodic protection of pipelines, which is equipped with potential test probes to test the protected pipelines. It is mainly used for the detection of cathodic protection parameters, and is an essential equipment for pipeline management and maintenance, and is arranged along the line according to the test function. The test pile can be used to test the potential, current and insulation performance of the pipeline, and can also be used to test the leakage of the coating and AC /DC interference.
