What is a pex pipe

Cross-linked polyethylene pipe (PEX) Generally speaking, this material is thermally welded. The advantages of pex pipe: good pressure resistance, nominal pressure 1.25MPa, de16mm burst pressure greater than 6MPa, de20mm burst pressure greater than 5MPa; wide temperature resistance range ：-70——95℃ (short-time 110℃); resistant to acid and alkali corrosion, can be used for the transportation of a variety of chemical substances; high temperature resistance, excellent low temperature performance; smooth inner and outer walls of the pipe, low resistance, no scaling; clean, no pollution, It can save people the pain of citing "yellow water" and "rusty water"; 　Use special pipe fittings, which can be installed conveniently and quickly, without tapping, buckling, and welding; easy to bend and flexible, saving pipe fittings; light weight, Compared with the same period, the pipe length is only 1/10 of that of the galvanized steel pipe; it has good thermal insulation performance; it has a long service life, at 70℃, working pressure ≤0.8MPa, and continuous service life of long-term durability according to standards. The defect is that the connection cannot be hot melted, which limits its application scope in HVAC and water supply.
