摘要
介绍了在役埋地管线外防腐层检测技术,叙述了PCM系统的工作原理、测量技术以及利用有关技术规程和标准判断防腐层等级的基本方法。并以现场实例分析测定和评估过程,讨论了PCM技术和评定标准在工程实践中的应用。
Based on an introduction to the detection technology of external anticorrosive coating of buried pipeline in service, the narration is given to the working principle, measuring techniques of PCM system, and basic methods of detecting the rank of anticorrosion coating according to the relevant technological regulation and standards. Then, applications of PCM technology and assessment standard to the practical projects are presented after the determining and assessing procedures are analyzed by means of worksite examples.
