Construction Technique of Inserting PE Pipe into Sleeve by Roller Bracket

以某DN300mm铸铁燃气管道改造工程为例,详细介绍了以废旧的DN300mm铸铁燃气管道为套管,将公称外径200mm的PE燃气管道采用钢制滚轮支架穿插入套管的施工方法。

Taking a construction project of DN 300 mm cast iron gas pipeline for example, the construction method of inserting PE gas pipe with nominal outside diameter of 200 mm into sleeve by roller bracket is introduced. The sleeve is waste DN 300 mm cast iron pipe.
