PE Pipe Production Process And Characteristics
- Jul 14, 2017 -

First, the connection is reliable: the heating between the polyethylene pipe system is melted and the strength of the joint is higher than the strength of the pipe.

Second, good resistance to low temperature impact resistance: low temperature brittle polyethylene brittle temperature can be safe in the range of -60-60 ℃ use. Because in the winter construction materials, impact resistance is good, there will not be crisp.

Third, good resistance to stress Cracking: high-density polyethylene has a low gap sensitivity, high shear strength and excellent scratch resistance, resistance to environmental stress cracking performance is also very prominent.

Fourth, good chemical resistance: high-density polyethylene pipe can be resistant to chemical corrosion, chemical substances, the existence of various in the soil will not cause any pipeline degradation. Polyethylene is electrically insulated, which is not subject to decay, rust or electrochemical corrosion, and it does not promote the growth of algae, bacteria or fungi.

Fifth, anti-aging, long life: containing 2-2.5 carbon black polyethylene pipe can be distributed evenly distributed or 50 years of use, will not be damaged by ultraviolet radiation.

Sixth, wear resistance: high-density polyethylene pipe and comparative tests show that steel pipe, HDPE pipe 4 times the wear and wear resistance of steel pipe. In the area of mud transportation, HDPE pipes have better wear resistance compared to steel pipes, which means that HDPE pipes have a longer life and a better economy.

Seventh, E tube flexible and easier to bend, by changing the pipeline engineering method can bypass the obstacles, in many occasions, flexible pipe fittings to reduce consumption and reduce installation costs.

Eighth, the flow resistance: high-density polyethylene pipe has a smooth inner surface, Manning coefficient is 0.009. Smooth performance and non-sticking to ensure that high-density polyethylene pipe has a higher than the traditional pipeline transmission capacity, but also can reduce the pipeline pressure loss and water consumption.

Ninth, simple handling: high-density polyethylene than concrete pipe, galvanized pipe and pipe light pipe, easy handling and installation, lower manpower and equipment requirements, which means that the project greatly reduces the installation cost.
