| Abstract: | The testing technology for the external protecting coating of pipelines using combined CIPS/DCVG techniques is studied. The application of this technology together with feeding method has successfully solved the problem that the CIPS and DCVG do not work on the pipeline without cathodic protection. This technology can be used for testing the electric potential of pipeline cathodic protection, evaluating cathodic protection performance, knowing the status of the protection coating and testing its deficiencies. |
