After years of development, PE pipe production equipment is gradually being built in the gas pipeline industry. At present, we have already said that PE pipe production equipment production enterprise requirements are high, need to be issued by the State Administration of Quality Supervision, Inspection and Quarantine of special equipment pressure pipeline production license.

In the PE pipe production equipment industry, the function of the raw material is the primary guarantee of the product function, the raw material of the temporary high strength, can ensure that the gas pipeline in a long enough service life to be able to accept high enough pressure. Only the raw materials are resistant to high-speed cracking and expansion to ensure that the gas pipeline will not occur unavoidable disasters. This is very important for the gas industry, where safety requirements are high. The risk of rapid cracking increases with the increase in pipe diameter, which makes the ability of raw materials to resist rapid cracking a key mechanical property of large diameter HDPE gas pipelines.

PE pipe production equipment in the PE gas pipe used in the raw materials are exported raw materials, secondary grade PE100 and PE80.PE gas pipe HDPE gas pipe general purpose materials are not consumed in large quantities in the international arena, and the strength and hardness of ordinary high-density polyethylene is higher than that of the general purpose materials for gas pipes. However, for the pipe, with the passage of time will occur aging, its mechanical function and physical properties will show signs of decay, aging will be transformed from the initial ductile damage to brittle damage. Regarding the process of decay and aging, ordinary gas pipe material is much slower than ordinary HDPE. Therefore, HDPE is mainly used as the common material for gas pipes at present.

In the relevant international standards ISO04437-1997 and GB15558.1, the materials lower than PE pipe production equipment have strict functional requirements to ensure a service life of 50 years under normal circumstances.
