100多年来人们都是用金属诸如铅、镀锌、铸铁等做水管,浑然不觉金属管易锈蚀所带来的水质污染。现在,一种新的材质管道正在大面积地构建新的都市血管——地下输水网络,这就是塑料管道。塑料管分为普通塑料管、复合塑料管、金属塑料复合管和玻璃钢管等4大类。一般来说,普通塑料管包括硬聚氯乙烯(UPVC)管、聚乙烯(PE)管、聚丙烯(PP)管和 ABS 管。复合塑料管包括 For more than 100 years, people use metal such as lead, galvanized iron and cast iron to make water pipes, unaware of the water pollution caused by easy rusting of metal pipes. Now, a new material pipeline is being built on a large area of ​​new urban vascular - underground water network, which is plastic pipe. Plastic pipe is divided into ordinary plastic pipe, composite plastic pipe, metal plastic composite pipe and glass pipe and other 4 categories. In general, common plastic pipes include rigid polyvinyl chloride (UPVC) pipes, polyethylene (PE) pipes, polypropylene (PP) pipes and ABS pipes. Composite plastic pipe included
