The material and advantages of PP air duct valve

PP actually refers to polypropylene, which is mainly used in indoor cold and hot water supply systems in buildings and industrial anti-corrosion ventilation systems. Compared with pipes of other materials, it has good advantages:

1. No corrosion: PP pipe valves can withstand the corrosion of PH value in a wide temperature range, ranging from 1 to 14 in high concentration of acid and alkali.

2. Wear resistance and no scaling: The inner wall of PP pipe valves and fittings is uniform and smooth, with small flow resistance and no scaling.

3. Reduce vibration and noise: PP pipe valve has excellent sound insulation performance, which can significantly reduce vibration and noise caused by liquid flow.

4. Anti-freeze cracking: PP material has excellent elasticity, so that the section of the pipe and pipe fittings can expand together with the frost heaving liquid without bursting. 5. Anti-condensation, less heat loss: PP material is a poor thermal conductor, which can reduce condensation and reduce heat loss.

6. Simple installation: PP pipe valve is light in weight, easy to install and operate, and has weldability.
