Water Hose PE Water Pipe Performance Advantages
Water Hose PE water pipe performance advantages
PE water pipe performance advantages
1. Reliable connection: Polyethylene pipe system between the use of electric hot melt connection, the joint strength is higher than the pipe body strength.
2. Low temperature impact resistance: PE low temperature embrittlement temperature is very low, in the -60 · 60 ℃ temperature range of safe use.
Winter construction, due to good impact resistance of the material, will not occur tube embrittlement.
3. Good chemical resistance: HDPE has a low gap sensitivity, high shear strength and excellent scratch resistance, resistance to environmental stress cracking performance is also very prominent.
4. Good chemical resistance: HDPE pipe can withstand the corrosion of a variety of chemical media, soil chemicals present in the pipeline will not cause any degradation of the role.
5. Aging resistance, long service life: 2. 2.5% of the uniform distribution of carbon black polyethylene pipe can be stored in the open air or use for 50 years, will not be subject to UV radiation damage.
6. Good wear resistance: HDPE pipe and steel pipe wear resistance comparison experiments show that HDPE pipe wear resistance of steel pipe 4 times. In the field of mud transport, compared with steel, HDPE pipe has better wear resistance, which means that HDPE pipe has a longer life and better economy.
7. Flexibility: The flexibility of the HDPE pipe makes it easy to bend and can bypass the obstructions by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe and reduce the installation cost.
8. Water flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009.
9. Easy handling: HDPE pipe is lighter than concrete pipes, galvanized pipes and steel pipes, it is easy to handle and install, lower manpower and equipment requirements, which means that the installation fee is greatly reduced.
With some cities in China to prohibit the use of galvanized steel pipe as a living water pipe, the non-metallic pipe, especially PE-based materials, the rapid development of a variety of composite pipe in the current pipeline area set off a "plastic on behalf of the steel," the era of change background, PE polyethylene water pipe to replace the traditional water supply pipe is an irresistible trend of historical development.
2. Work characteristics
(1) fused welding process is simple, the construction speed, the operation process can achieve semi-automatic and fully automated, low labor intensity.
(2) interface is safe and reliable.
