| Abstract: | The Stray Current Mapper was used to study the detection and evaluation measures about the stray current by analyzing its characteristic and the cause of formation. It is helpful to find out the stray current around the buried pipeline and make the strategy to control the corrosion of pipeline. In the paper, the application of the stray current mapper to buried steel pipeline is presented. |
