Can PVC pipes be used as drinking water pipes? Isn't vinyl chloride harmful to people?

PVC水管是可以作为饮用水的水管的，PVC材质的主要成分是聚氯乙烯，而不是氯乙烯，而聚氯乙烯是对人体无害的。但是由于有PVC-U单体和添加剂渗出，只适用于输送温度不超过45℃的给水系统中。

PVC water pipes can be used as drinking water pipes. The main component of PVC material is PVC, not vinyl chloride, and PVC is harmless to human body. However, due to the exudation of PVC-U monomer and additives, it is only applicable to the water supply system with the transmission temperature not exceeding 45 ℃.

PVC管（PVC-U管） 硬聚氯乙烯管，是由聚氯乙烯树脂与稳定剂、润滑剂等配合后用热压法挤压成型，是最早得到开发应用的塑料管材。PVC-U管抗腐蚀能力强、易于粘接、价格低、质地坚硬，塑料管道用于排水，废水，化学品，加热液和冷却液，食品，超纯液体，泥浆，气体，压缩空气和真空系统的应用。

PVC pipe (PVC-U pipe) is made of PVC resin, stabilizer, lubricant, etc. and then extruded by hot pressing. It is the earliest plastic pipe developed and applied. PVC-U pipe has strong corrosion resistance, is easy to bond, low price and hard texture. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling liquids, food, ultra-pure liquid, mud, gas, compressed air and vacuum systems.

PVC管的应用情况：Application of PVC pipe:

1、PVC管的本质是一种真空吸塑膜，用于各类面板的表层包装，所以又被称为装饰膜、附胶膜，应用于建材、包装、医药等诸多行业。其中建材行业占的比重最大，为百分之六十，其次是包装行业，还有其他若干小范围应用的行业。

The essence of PVC pipe is a kind of vacuum plastic absorption film, which is used for the surface packaging of various types of panels, so it is also called decorative film and adhesive film, which is used in many industries such as building materials, packaging, medicine and so on. Among them, the building materials industry accounts for the largest proportion, accounting for 60%, followed by the packaging industry, as well as a number of other small-scale applications.

2、PVC管分为PVC给水管和排水管两种，用于市政给排水、工业给排水、民用给排水、灌溉、植被浇水等。

PVC pipes are divided into PVC water supply pipes and drainage pipes, which are used for municipal water supply and drainage, industrial water supply and drainage, civil water supply and drainage, irrigation, vegetation watering, etc.
