摘要
介绍了聚乙烯(PE)管道的4种失效形式:韧性失效、脆性失效、焊接接头失效以及缺陷失效,给出了4种失效形式对PE管道产生的安全影响,并给出了相关的解决办法,为PE管道的安全运行提供了一定的参考作用。
This paper introduces four failure modes of polyethylene(PE)pipelines,which include brittle failure,ductile failure,welded joints failure and defect failure.The impacts of these four failures on PE pipeline are demonstrated as well as solutions to offer reference for safe operation of PE pipelines.
