What are the advantages and disadvantages of PE composite pipes for water supply?
1. hot melt connection pipe and pipe fittings are connected to each other by the same thermal plastic, using special equipment to connect hot melt surface heating parts, connected at the contact surface of the material of the main body of mutual fusion, after cooling the connection as a whole. The hot melt connection has butt type hot melt connection, socket type hot melt connection and electrofusion connection.2. electric melting connection by the same thermoplastic plastic pipe, insert the fused fittings made from fused, fused fittings for connecting tool power depends on the electric resistance wire melting pipe internal pre buried produce the quantity of heat required for welding, cooling pipe and electric melting pipe connected with a a whole.
PE (polyethylene) pipe, now used in actual engineering more water pipes.Advantage：(1) good low temperature performance(2) resistance to mechanical shock;(3) tough and coiledShortcoming:(1) melting point of 100 to 130 degrees Celsius, should not be used for hot water pipeline, should be used for operating temperature is not greater than 40 degrees celsius.(2) easy stress cracking and difficult to dyeScope of application:Suitable as cold water pipe, widely used as drinking water pipe and rain pipe
PE composite pipes have a wide range of standards.Simply put: CJ/T 123124, water supply steel skeleton, polyethylene plastic composite pipeAdvantage：1, pipes, pipe fittings have reinforced skeleton. Pipe is welded steel wire, pipe is punched steel plate. (other standard pipe fittings are made of pure PE pipe fittings)2, and PE ratio, good anti cracking performance. It includes: slow crack growth and rapid crack cracking.3 and CJ/T 123, the standard is nominal internal diameter. With the valve, instrument, through the national standard flange matching, convenient and quick.The advantages and disadvantages of other equivalent PE pipe line.
