The main characteristics of PVC air duct.

1. Beautiful, light weight: the inner and outer walls of PVC air duct are made of soft PVC, the inner wall is smooth, the outer wall is corrugated, and the reinforcement layer is reinforced by white strong rigid PVC plastic bar spiral.

2. Small bending radius: The bending radius of the PVC air duct is small, which is easy to install and layout.

3. Acid and alkali resistance, chemical resistance: PVC air duct has good acid and alkali resistance and chemical resistance, suitable for various industrial and commercial environments.

4. Strong resistance to bending, stretching and resilience: PVC air pipes can withstand bending and stretching to a certain extent, and have good resilience.

5. Long service life: the service life of PVC air duct is longer, according to the pilot data of the Ministry of Construction, the service life is 50 years.

6. Easy installation and reliable connection: PVC air pipe has excellent welding performance, pipes and fittings can be connected with hot melt and electric burning, easy installation, reliable connection, and the strength of the connection part is higher than the strength of the pipeline.

7. Save construction costs: Compared with the cast iron pipe system with the same specifications, the comprehensive cost of PVC air pipes is lower.
