地下管道防腐层检漏仪的使用

Use of Leak Detector in Anticorrosion Coating of Underground Pipe

为了检查地下金属管道防腐层损伤、漏包等缺陷的准确位置,地下管道走向及估测管道埋土深度,使用了SL-Ⅱ型地下管道防腐层检漏仪。文中介绍了仪器的主要性能、使用原理、方法及操作要点。检测结果表明,该仪器使用简单方便且准确。

In order to find proper location of fault, holiday and other defects in anticorrosion coating of undergrounder pipe, laying direction and depth of the pipe, SL-II type of leak detector for under- grounder pipe is used. This paper introduces the main properties, principle and operation way of the detector. The practice application shows that the detector is easy to use and the measuring re- sult is correct as well
