GAS HDPE gas and biogas pipelines are produced with high-performance PE100-grade special raw materials and are manufactured in strict accordance with national gas pipeline standards. They are suitable for the safe transportation of various combustible gases such as natural gas, liquefied petroleum gas, and biogas. They are the core pipes of urban gas pipeline networks and rural biogas systems. The product material is stable, non-toxic and tasteless, and does not react with the transmission medium to ensure the safety and cleanliness of gas supply from the source.
The pipe has excellent flexibility, impact resistance and corrosion resistance. It is not subject to soil acid and alkali erosion when buried in the ground, and does not require additional anti-corrosion treatment. It is not easy to crack in low temperature environment. It can adapt to uneven settlement of the foundation and greatly reduce the risk of leakage. It adopts hot-melt docking and electrofusion connection, and the interface strength is higher than that of the pipe body. It is sealed reliably and has no leakage. The service life can reach more than 50 years, and the construction is light and the operation and maintenance cost is low.
It is widely used in urban municipal gas pipeline networks, residential gas supply, industrial park gas transportation, rural biogas centralized gas supply, coal-to-gas projects, etc. It has high safety performance and stable operation. It is a safe, efficient and durable pipeline in modern gas and biogas transmission and distribution systems.
