Plastic HDPE Gas Pipes

HDPE (high density polyethylene) gas pipe is a type of gas polyethylene pipe made mainly from high-density polyethylene (HDPE) resin, with the addition of other auxiliary materials, and extruded into shape. HDPE gas pipe have many excellent properties and are used in the field of gas transportation. We will thoroughly solve the corrosion and joint leakage problems of steel pipes and cast iron pipes, thereby ensuring the safe operation of the gas pipeline network system. The PE material used for PE gas pipes is an inert material that can withstand the erosion of various chemical media. The friction coefficient of the hdpe pipe wall is low, the flow resistance is small, and the conveying capacity is strong. It adopts electric heating fusion connection, and the interface strength is higher than that of the pipe body. The high toughness PE fracture elongation generally exceeds 500%. PE gas pipes have good seismic performance, resistance to slow crack growth (SCG), rapid crack propagation (RCP), flexibility, and scratch resistance.

 

HDPE gas pipe have strong adaptability to uneven settlement of pipe foundations, strong wear resistance, and can be used in various non excavation methods. They are easy to construct and install in larger areas, with low system costs and maintenance expenses, which can significantly reduce engineering costs.

 

1. Cracking resistance: HDPE gas pipelines have excellent resistance to environmental stress cracking, which means they can maintain their performance unaffected in harsh environments.
2. Flexibility performance: Compared with ordinary HDPE water supply pipe and HDPE fire pipe, the fracture elongation of HDPE gas pipes generally exceeds 500%, making them highly adaptable to uneven settlement of foundations and possessing excellent seismic performance.
3. Scratch resistance: HDPE water pipe have excellent scratch resistance, reducing the possibility of pipeline damage caused by stress concentration due to scratches.
