Product Description
HDPE Gas Pipe Description
The gas pipeline is one of the most important components of the pipeline network in a city. The gas itself has certain dangers. If there is a leakage, it is easy to cause great harm, so the safety of HDPE gas pipes is very important. The replacement of the pipe network is also a very troublesome project. Excellent HDPE gas pipes have a service life of 2-3 times that of traditional pipes, up to 50 years. They have good properties, low installation costs and strong safety, so HDPE pipes are ideal used for gas transmission.

1) Good hygienic performance: PE pipe processing without adding heavy metal salt stabilizer, non-toxic material, no scaling layer, no bacteria, a good solution to the secondary pollution of urban drinking water. 2) Good corrosion resistance: Except for a few strong oxidants, it can resist the erosion of various chemical media; no electrochemical corrosion. 3) Long service life: Under rated temperature and pressure conditions, PE pipeline can be used safely for more than 50 years. 4) Better impact resistance: PE pipe has good toughness, high impact strength, heavy objects directly pressed through the pipeline, will not lead to pipeline rupture. 5) Reliable connection performance: PE pipe hot-melt or electric-melt interface strength is higher than the pipe body, the joint will not be broken due to soil movement or live load. 6) Good construction performance: light pipeline, simple welding process, convenient construction, low comprehensive cost of the project. Pipeline Connection: 1) Electric-thermal weldability: The straight pipe and straight pipe, straight pipe and pipe fittings are connected by special electric-thermal welder. Usually used for pipes under 160mm. 2) Hot-melt butt joint: Use special butt welder pipe connection, generally used for more than 160mm pipes. 3) Steel-plastic connection: flange, thread and other methods can be used to connect. Application: Hesu Pipe Industry's high-performance high-density polyethylene water pressure pipes are suitable for municipal and industrial transmission systems for potable water, sewer, drain, mining, irrigation, and reclaimed water.
