非开挖探测燃气管道防腐层技术的研究与应用

The Study on and Application of Trenchless Techniques for Detecting the Anticorrosive Coating of Gas Pipelines

非开挖探测管道防腐层技术操作简便、节约成本,为燃气管道维护、改造、更新及安全运行提供了科学依据。介绍了非开挖探测管道防腐层技术的多频管中电流法和皮尔逊法,并在操作、技术等方面进行了比较,确定了更适用于太原市煤气管道的探测方法。

The trenchless techniques for detecting the anticorrosive coating of gas pipelines,which is easy and simple to handle and can save the cost,provides scientific basis for the maintenance,transformation and safe operation of the gas pipelines.This paper introduces some trenchless techniques for detecting the anticorrosive coating of gas pipelines such as PCM and Pearson Method,and through the comparison in aspects of operation,and technique,etc.,determines the detecting method that is more suitable for the application in Taiyuan＇s gas pipelines.
