GAS HDPE pipeline adopts PE100 grade gas specific high-density polyethylene raw material, which is formed by professional extrusion process and strictly follows the national gas pipeline standards. It is designed for the transportation of urban natural gas, liquefied petroleum gas, biogas and other gases, and is an ideal pipe material to replace traditional metal gas pipes. The pipe material is hygienic, non-toxic, and stable, ensuring the safety of gas transmission from the source. It can be buried for a long time without polluting the transmission medium.
The pipeline has core advantages such as reliable connection, corrosion resistance, low temperature resistance, and strong flexibility. It adopts hot melt and electric melt connection, and the joint strength is higher than that of the pipe body, achieving zero leakage throughout the system; Resistant to soil corrosion and chemical media erosion, no need for anti-corrosion treatment, resistant to impact and non brittle cracking in low temperature environments, able to adapt to uneven settlement of foundations, with a service life of over 50 years. At the same time, the pipe material is lightweight, easy to transport and construct, and can be laid without excavation, greatly reducing the overall cost of the project.
GAS HDPE pipes are widely used in urban gas pipeline networks, residential gas supply, industrial park gas transmission, rural coal to gas conversion projects, etc. The diameter coverage is comprehensive, and the pressure resistance level matches the needs of different scenarios. With the characteristics of safety, stability, reliable operation, and low operation and maintenance costs, it has become the mainstream choice of pipe materials for modern gas transmission and distribution systems.
