Can PE water supply pipe and PE gas pipe be mixed?

Can PE water supply pipe and PE gas pipe be mixed?

The production execution standards of PE water supply pipes and PE gas pipes are different, the pressure bearing of pipes is different, and the environmental protection standards are also different, so they cannot be universal.

PE water supply pipe implementation standard GB / T 13663-2000

The materials of polyethylene pipes are divided into five grades of PE32, PE40, PE63, PE80, and PE100 internationally, while the materials used for gas pipes and water supply pipes are mainly PE80 and PE100. There is no grading of special materials for polyethylene pipes in China, which makes it difficult for domestic manufacturers of polyethylene gas pipes and water supply pipes to choose raw materials, and also brings a lot of hidden dangers to the use of polyethylene pipes.

Therefore, the National Bureau of Standards made a large number of revisions in the new standard GB / T13663-2000, which stipulates that different levels of PE80 and PE100 of the water supply pipe correspond to different pressure strengths, and removes the tensile strength performance in the old standard, and increases the fracture Elongation (greater than 350%), which emphasizes basic toughness.
 
PE gas pipe implementation standard GB 15558.1-2003

This part of GB15558 stipulates the definition, materials, appearance, geometric dimensions, mechanical properties, physical properties of buried polyethylene pipes for gas (hereinafter referred to as "pipes") which are made of polyethylene compounding materials as the main raw materials. Signs, inspection rules and packaging, transportation and storage. This section also specifies the basic performance requirements of the ingredients, including classification. This section applies to buried polyethylene pipes for gas manufactured with PE80 and PE100 materials. The nominal outer diameter of the pipe is 16mm ~ 630mm. When transporting artificial gas and liquid busy LPG, the adverse effects of other components present in the gas (such as aromatic hydrocarbons and condensate) on the performance of the pipe at certain concentrations should be considered.If you want to know more about it please do not hesitate to contact me.

PE water supply pipe and PE gas pipe are different in appearance

PE water supply pipe is blue or black with blue bar

PE gas pipe is yellow or black with yellow bar
