本文回顾了 PVC 管问世以来在给水工程上日趋广泛的应用,介绍了国内现状和进展,认为我国管材工业“可以越过球铁阶段而直接进入以 PVC、PE 等塑料管材为主体的非金属阶段。”从环保、理化性能、生产、施工安装、经济对比等方面展开了论述,预测“未来十年内,未增塑聚氯乙烯管将逐步取代钢、铸铁管而成为主要的上水管材之一”。
This paper reviews the widespread application of PVC pipe in water supply engineering since the advent of PVC pipe and introduces the domestic current situation and progress. It is believed that China’s pipe industry can “go beyond the ductile iron pipe and directly enter the non-metal phase with plastic pipe such as PVC and PE. ”From the environmental protection, physical and chemical properties, production, construction and installation, economic comparison and other aspects of the discussion, predicts that“ the next decade, unplasticized polyvinyl chloride pipe will gradually replace steel, cast iron pipe and become one of the main water pipe ” .
