摘要
PCM是一种通过遥测地下管道中电流,既可进行管道定位又可用于管道防腐层状况检测的设备。阐述了PCM系统组成、工作原理及用途。并通过福州市煤气中压管道防腐层状况的普查情况,对PCM在地下管线探测中的应用及检测过程的应用条件进行了分析。
The PCM System is a kind of instrument used in the positioning of pipelines and the detection of piping anti-corrosive coating by remote measurement of the electric current in underground pipelines. The PCM system composition, operating principle and function are present in the paper. The author made an analysis of the detection of underground utilities and detection procedure conditions according to the results of surveying the anti-corrosive coating of a media-pressure coal-gas piping in Fuzhou City.
