埋地钢管外防腐层直接检测技术与方法

Direct Inspection Technology and Method for External Anticorrosion Coating of Buried Steel Pipe

根据多年检测地下管道外防腐层的实践经验,系统地论述了地下管道外防腐层检测前沿的几种理论方法。通过对这些理论方法和检测技术的分析,以期能对我国油气等埋地管网腐蚀评价的技术规范制定、实际管道腐蚀检测的实施、埋地管网腐蚀评价起到指导和借鉴作用。

According to many years experience in inspecting the external anticorrosion coating of underground pipeline, several frontier theoretical methods for inspecting the external anticorrosion coating of underground pipeline are introduced systematically. By analyzing the theoretical methods and the inspection technologies, it is hoped that they can play a guidance and reference role for the establishment of technique code for corrosion evaluation of buried oil, gas and other network in China, the implementation of actual pipeline corrosion inspection and the corrosion evaluation of buried network.
