摘要
燃气用埋地聚乙烯管道在实际运行环境中会发生变形,这种变形会对管道的电熔鞍型修补、开支路等操作产生极大的影响,甚至引起焊接失败。针对聚乙烯管道的变形进行分析,从而提出降低变形影响和避免电熔鞍型焊接失败的措施。
The buried polyethylene pipe for gas will deform in the actual operation environment. This deformation will cause welding failure for the electric pipeline saddle repair and branch operation. In this paper, the deformation of PE pipe is analyzed, and the measures to reduce the influence of the deformation are put forward.
