This part of GB15558 specifies the definition, materials, appearance, geometric dimensions, mechanical properties, physical properties, marking, inspection rules, packaging, transportation and storage of buried polyethylene pipes for gas (hereinafter referred to as "pipes") made of polyethylene mixed materials as the main raw materials and extruded. This part also specifies the basic performance requirements of mixed materials, including classification. This part is applicable to buried polyethylene pipes for gas made of PE80 and PE100 materials. The nominal outer diameter of the pipe is 16mm to 630mm. When transporting artificial coal gas and liquid petroleum gas, the adverse effects of other components in the gas (such as aromatic hydrocarbons, condensate) on the performance of the pipe at a certain concentration should be considered.

The following is the definition of the pipe material section, including the size, performance, inspection and packaging of the mixed materials. The wood section is applicable to the PF and PF materials for the gas separation of the material. The nominal outer diameter of the village is 16ac.ram:
When transporting coal to the liquefied core, the small influence of the pipe (such as: the potential for re-entry, the condensation filter, and the degree of the pipe) should be considered.
