常用给排水管材管件耐寒能力分析

Analysis of Cold Resistant Ability of Commonly Used Water Supply and Drainage Pipe Fittings

管材管件是工程建设必须的材料之一。该文介绍了目前常用的给排水管材管件的种类和应用,针对低温严寒天气的气候环境下塑料管材管件的爆裂原因,分析了常用给排水塑料管材管件的耐低温能力和国家标准要求,并提出耐寒防护注意事项。

Pipe and pipe fittings are one of the necessary materials for the engineering construction. In this pa- per, the types and applications of pipe fittings were introduced. In view of the reasons for bursting of plastic pipe fit- tings in the climate environment of low temperature and cold weather, the low temperature resistant capacity of plas- tic pipe fittings and the requirement of national standards were analyzed. And the cold protections are proposed.
