1. Light weight (density 0.9-1.2g/cm3), low price.
2. Smooth inner wall, small friction coefficient, improve the efficiency of fluid transmission.
3. It has high impact strength and its ring steel is twice as high as that of ordinary PVC-U.
4. Weather resistance is good, it can be used at - 30 ~70 ~C, and the dimensional stability of the pipe is good when the temperature changes.
5. Special composite multi-layer structure greatly improves the sound insulation performance of pipes.
6. Strong self-ignition and self-extinguishing performance.
7. It has corrosion resistance.
8. The service life of pipeline is increased, which is 4-7 times that of common pipeline.
9. The installation cost of composite drainage pipes is lower than that of ordinary pipes, and the performance of composite drainage pipes is higher than that of ordinary polyethylene pipes due to many factors such as corrosion resistance, wear resistance and weather resistance.
