Hard polyvinyl chloride (PVC-U) water supply pipe and fittings as a mature water supply pipe has acid resistance, alkali resistance, corrosion resistance, good pressure resistance, high strength, light weight, low price, low fluid resistance, no secondary pollution, in line with health requirements, convenient construction and operation and other superior performance, vigorously promote PVC-U water supply pipe, In line with the world's guidelines for the development of chemical building materials, in line with the development needs of improving people's living standards. PE environmental health water supply pipe fittings are produced with PE100 or PE80 as raw materials. Specifications, performance and dimensions conform to ISO4427-1:2007. PE ring water supply pipe has the characteristics of good flexibility, strong corrosion resistance, light weight and excellent impact resistance. Pipe fittings can be connected by hot melt socket, hot melt butt, capacitor butt, etc., so that the pipe fittings are fused into one, the system is safe and reliable, and the construction cost is low.
