PE管电熔焊接和热熔焊接在施工中的比较

目前,塑料管道在中国正在稳步发展,PE管、PP-R管、UPVC管都占有一席之地,其中PE管强劲的发展势头最为令人瞩目。PE管的使用领域广泛。其中燃气管和给水管是其两个最大的应用市场。PE管作为煤层气输送管线在施工中得到普遍的应用,根据以往施工实践的总结,对于PE管的热熔和电熔两种比较成熟的施工方法进行分析和比较。

Comparison of Electrofusion Joining and Hot-melt Welding for PE Pipes in the Construction

Currently,plastic pipes in China are steadily developing,such as PE pipes,PP-R pipes,UPVC pipes.Among these pipes,application field of PE pipes is most wide,gas pipes and water supply pipe are two main application field.PE pipes as coalbed methane pipelines have widely been applied in the construction,according to past construction practices,hot-melt welding process and electrofusion welding process have been analyzed and compared.
