PVC Pipe Common Sense

Our country plastic pipeline develops very fast, the nice is improving unceasingly. pe water deliver pipe is broadly utilized in constructing water deliver, building drainage, underground drainage pipe, constructing heating, gas transmission pipe, electric and telecommunication protection pipe,industrial pipe, agricultural pipe, etc. . It is mainly used in the fields of city water supply, city gas supply and farmland irrigation. Pe (polyethylene) material is widely used in the field of water supply pipe manufacturing because of its high strength, corrosion resistance and non-toxic characteristics, it is an ideal pipe material to replace common iron water supply pipe. 

Polyethylene (PE) pipe has become the PVC-U pipe, the world’s second largest volume of plastic pipe, varieties, widely used in gas transportation, water supply, sewage, agricultural irrigation, oil fields, mines, chemicals and telecommunications and other fields. Polyethylene (Pe) pipe applications began in the 1940s, the first generation of Pe pipe-grade Resin copolymer content is low, such as PE32, PE40, PE63 grade resin, the extruded polyethylene pipe will be brittle when it is subjected to Long-term hydrostatic strength test. The second-generation Resin is of PE80 grade and provides the content of Comonomer on the basis of the first-generation Resin, the third generation resin is PE100 grade, the PE100 resin has higher density and rigidity, and the creep resistance at 20 °C and 50 years is improved, at the same time, the ESCR has good performance. Currently, PE80 and PE100 grade medium or high-density polyethylene pipes are used for gas transmission, PE80 and PE100 grade medium or high-density polyethylene pipes are usually used for PE water supply pipes, and PE63 has been gradually phased out; PE32 and Low-density polyethylene are commonly used for irrigation.
