Composition: Steel pipe, PE coating (or EP coating), outer galvanized Zn and Ni
Color: Red is for transporting hot water and blue is for cold water (top water)
Usage: supply water in industry, supply water for civilian, collect and transport rain water, transport sewage, foods production, medicine, mechanism (inside and outside doors)
Performance:
1. Good appearance: outer color is silver
2. Excellent anti-erosion: coating material is PE or EP, plating material is Zn and Ni
3. Can be used for 70 years
4. Low price, high quality
5. Smooth, sturdy, uniform coating
6. Can support high pressure (At 3Mpa pressure, without leakage)
7. Strong ability to avoid shaking (base material is steel)
8. Coating can be stick to steel pipes strongly
9. Low coefficient of expansion due to heat(under 70℃)
10. Easy to connect and install
11. Be sealed completely and don’t leak liquid
12. We introduce the advanced technology, reduce the cost and boost the efficiency
13. Good electrical insulation, without electrical erosion
