Can PE water supply pipes and PE gas pipes be mixed?Can PE water supply pipes and PE gas pipes be mixed?
PE water supply pipeline is different from PE gas pipeline production and implementation standards, the pipeline pressure is also different, and the environmental protection standards are also different, so it cannot be used universally. Let's talk about the PE water supply pipe production line in detail
The materials of polyethylene pipes are divided into PE32, PE40, PE63, PE80 and PE100, while the materials of air pipes and water supply pipes are mainly PE80 and PE100. There is no classification of special materials for polyethylene pipes in my country, which makes it difficult for domestic polyethylene gas pipe and water supply pipe manufacturers to choose raw materials, and it also brings many hidden dangers to the use of polyethylene pipes.
Therefore, the National Bureau of Standards has made a lot of amendments to the new GB/T13663-2000 standard, stipulating that different grades of water supply pipes PE80 and PE100 correspond to different pressure strengths, and canceled the tensile strength performance in the old standard, and increased the fracture extension. Elongation rate (greater than 350), which emphasizes the basic toughness.
PE water supply pipe production line
This part of the PE gas pipe executive standard GB15558.1 stipulates the definition, material, appearance, geometric dimensions, mechanical properties, physical properties, markings, inspection rules and packaging of buried polyethylene pipes (hereinafter referred to as "pipes") for natural gas production , Transportation and storage, these pipes are extruded with polyethylene mixture as the main raw material. This section also specifies the basic performance requirements of mixed ingredients, including classification. This section applies to buried polyethylene pipes for natural gas production made of PE80 and PE100 materials. The nominal outer diameter of the pipeline is 16 mm to 630 mm. When transporting man-made gas and liquefied petroleum gas, the adverse effects of other components in the gas (such as aromatic hydrocarbons and condensate) on the performance of the pipeline should be considered at a certain concentration.
The requirements of PE gas pipes are stricter than that of water pipes, so the cost performance is also different. The price-performance ratio of polyethylene gas pipeline is much higher than that of polyethylene water supply pipeline. Some companies in the market use low prices to attract customers and steal materials to cover up potential risks in the later stages. Buyers should keep their eyes open when buying.
