Can PE water supply pipe and PE gas pipe be mixed?
PE water supply pipe and PE gas pipe production implementation standards are not the same, the pipeline pressure is not the same, environmental protection standards are also different, so it is not universal. PE water supply pipe implementation standard GB/T13663-2000 international polyethylene pipe (polythylenepipe) material is divided into PE32, PE40, PE63, PE80, PE100 five grades, and used for gas pipe and water supply pipe material is mainly PE80 and PE100. China's polyethylene pipe special material is not graded, which makes the domestic polyethylene gas pipe and water supply pipe manufacturers to choose raw materials more difficult.

Internationally, the material of polyethylene pipe (polythylene pipe) is divided into five grades: PE32, PE40, PE63, PE80 and PE100, while the material used for gas pipe and water supply pipe is mainly PE80 and PE100. There is no classification of special materials for polyethylene pipes in China, which makes it difficult for domestic polyethylene gas pipe and water supply pipe manufacturers to choose raw materials, and also brings a lot of hidden dangers to the use of polyethylene pipes.
Therefore, the National Bureau of Standards has made a lot of revisions in the new GB/T13663-2000 standard, stipulating that different levels of PE80 and PE100 for water supply pipes correspond to different pressure strengths, and removing the tensile strength properties in the old standard, while increasing the elongation at break (greater than 350%), that is, emphasizing basic toughness.
This part of the GB15558 specifies the definition, material, appearance, geometric size, mechanical properties, physical properties, marking, inspection rules, packaging, transportation and storage of the buried polyethylene pipe for gas (hereinafter referred to as "pipe") with polyethylene mixture as the main raw material. This part also specifies the basic performance requirements for blending, including grading. This part is applicable to buried polyethylene pipes for gas made of PE80 and PE100. The nominal outer diameter of the pipe is 16mm to 630mm. When transporting artificial gas and liquid busy petroleum gas, the adverse effects of other components (such as aromatic hydrocarbons and condensate) in the gas on the performance of the pipe at a certain concentration should be considered.

The requirement of PE gas pipe is stricter than that of water pipe, so there is also a difference in price,PE gas pipe price is much higher than PE water supply pipe, Some businesses in the market use low prices to attract customers and secretly change materials, which has hidden safety hazards for the later stage. Buyers should keep their eyes open when purchasing,Check whether the merchant meets the qualification of gas pipe production, and do not be careless.!
