PE gas pipe series

　　Product Advantage

　　Reliable connection

　　The polyethylene pipe system is connected by electric melting method, and the strength of the joint is higher than the strength of the pipe body. Polyethylene pipe and other pipeline adopt flange connection. It is convenient and quick.     

　　The brittlement temperature of polyethylene is very low, and it can be used safely from  -60℃ to 60℃. In winter, because of good impact resistance, the pipe brittle fracture will not happen.

　　Excellent resistance to stress cracking

　　HDPE has the advantages of low notch sensitivity, high shear strength and excellent scratch resistance, and it is resistant to environmental stress cracking.

　　Excellent chemical resistance

　　HDPE pipeline corrosion resistant variety of chemical medium, the presence of soil chemical substances will not produce any degradation effect on pipeline.

　　Aging resistance and long service life

　　Polyethylene pipes with uniform distribution of carbon black with 2-2.5% can be stored outside the open air for 50 years and will not be damaged by ultraviolet radiation. 

　　Good wear resistance

　　The abrasion resistance test of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times of that of steel pipe. The HDPE pipeline has better wear resistance, which means that the HDPE pipeline has longer service life and better economic performance.

　　Good winding property

　　It is easy to make HDPE pipe bending. In engineering, the obstacle can be passed by changing the direction of the pipeline. On many occasions, The flexibility of the pipeline can reduce the amount of pipe fittings and reduce installation costs.

　　The flow resistance is small

　　The HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. The smooth surface and non adhesion ensure that the HDPE pipeline has higher conveying capacity than the traditional pipe. but also reduce the pipeline pressure loss and water consumption. At the same time, the pressure loss and water delivery energy consumption of pipeline are reduced.

　　Easy to transport

　　HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to carry and install, and have lower manpower and equipment requirements, which means that the cost of installation is greatly reduced.

　　Diversification of construction methods

　　HDPE pipeline has a variety of construction technology, in addition to the traditional excavation method can be used in the construction, it can also use a variety of new trenchless technology, such as pipe jacking, directional drilling, pipe repair, cracking pipe and other ways of construction. This is the only choice for some sites that are not allowed to dig, so the application of HDPE pipeline is more extensive.
