1. Excellent in chemical corrosion, no rust;
2. With self extinguishing and flame retardant;
3. Excellent in anti aging, can be used 20years to 50 years between the temperature from subzero 15 to 60 degrees Celsius;
4. Wall is smooth, inner wall surface tension, it is difficult to form scale, the fluid transport capacity of 43.7% higher than the cast iron pipe;
5. The weight is light, easy to flaring, bonding, bending, welding, pipe installation workload is only 1 / 2 to the steel pipes, low labor intensity, short duration;
6. Good electrical properties of resistance, volume resistance of 1 to 3 x 105Ω.cm, breakdown voltage 23 to 2kv/mm;
7. The toughness of PVC pipe is low, linear expansion coefficient is high, operating temperature range is narrow.
