| Abstract: | The pipeline current mapper manufactured by radiodetection company has been widely applied to the pipeline inspection.At present,it is a major method of pipeline coating inspection.According to the practical experience,the application of PCM to coating evaluation, insulated joints,pipeline leakage locating and sacrificial anodes has been introduced.Meanwhile,the precaution and advice during the appliacation of PCM are also presented.Thus PCM can play an important role in the inspection of pipeline. |
