PVC-U water supply pipe

PVC-U water supply pipe
PVC-U pipes are mainly made of sanitary grade polyvinyl chloride (PVC) resin, with the addition of appropriate stabilizers, lubricants, fillers, color enhancers, etc. They are extruded by plastic extruders and injection molded by injection molding machines. Through cooling, curing, shaping, inspection, packaging and other processes, the production of pipes and fittings is completed.
Compared with traditional pipelines, PVC-U pipes have the advantages of light weight, corrosion resistance, low water flow resistance, energy saving, quick installation, and low cost. They have been widely promoted and applied, and the benefits are significant. Since the 1980s, China has been piloting the use of PVC-U pipes in municipal and construction projects. After more than 10 years of promotion, PVC-U pipes have made significant progress, but per capita consumption is still less than 1/15 of developed countries and regions such as the United States, Japan, and Western Europe. With the joint notice of the Ministry of Construction and five other departments to vigorously develop chemical building materials, the promotion and application of PVC-U plastic pipes have been increased. Sanitary and environmentally friendly PVC-U water supply pipes have continuously replaced traditional pipes with high energy consumption, high pollution, high cost, and low hygiene indicators. Widely used in urban tap water supply projects, building interior and exterior water supply projects, industrial and mining enterprise water supply projects, underground fire water supply projects, agricultural water conservancy and irrigation projects, garden and horticultural greening water supply projects, aquaculture water supply and drainage projects, etc., and has achieved good economic and social benefits.
