摘要
多频管中电流检测法(PCM)已得到广泛应用。针对油气管道非开挖检测准备工作和检测过程中应该引起注意的问题,后期数据处理及曲线划分,结合聊泰天然气长输管线现场应用,提出了一些建议。目的是进一步提高多频管中电流测绘系统的检测效率和检测精度。
A detailed introduction about the principle,preparations,attentions,data processing of the Pipeline Current Mapping System(PCM) during the no-dig inspection of oil & gas pipelines is given.Connecting to the inspection application of the Liaotai long pipeline,some suggestions to improve the efficiency and accuracy of inspection of PCM are proposed.
