摘　　要：PE燃气管道是压力管道的一种。在用的PE燃气管道要进行全面检验,但是目前关于PE燃气管道的全面检验还没有形成一套标准体系。综述了对于现有的PE燃气管道检验检测的技术难点,例如定位困难、泄漏点确定困难、PE燃气管道失效机理不明等,并总结了现有的、有针对性的解决方法。PE gas pipeline is a kind of pressure pipeline, it should be conducted a comprehensive inspection during lifetime, but the comprehensive inspection has not yet formed a set of standard system. This article introduced the current technical difficulties, such as difficulties to locating pipeline, difficulties to locating leak point, unknown failure mechanism of PE pipeline, etc., and summarized existing useful solutions.
