In the design of gas transmission and distribution, Plastic PEX Manifolds ( https://www.ppsu-pex-fittings.com/product/pex-manifolds/ ) include steel pipes and cast iron pipes. However, with the passage of time, the disadvantages of poor corrosion resistance, high cost, and inconvenient transportation and installation of metal pipes have gradually emerged, so people have turned their attention to plastic pipes.

Polyethylene pipe (hereinafter referred to as PE pipe) is a new generation of gas delivery pipe. It is an extruded pipe made of polyethylene as the main raw material. Compared with traditional metal pipes, it has corrosion resistance; light weight and density Only 1/8 of steel; long service life, up to 50 years; high strength, good toughness, can withstand stratum changes without breaking; simple construction and other advantages, it is a new product for the upgrading of gas pipelines.

At present, Poly PEX Fittings ( https://www.ppsu-pex-fittings.com/ ) have been widely used in gas medium and low pressure pipe networks.
