In addition to improving the service life of steel pipes, anti-corrosion of steel pipes is also manifested in the following aspects:

1. Combine the mechanical strength of the steel pipe with the corrosion resistance of the plastic;

2. The outer wall coating is more than 2.5mm, resistant to scratches and bumps;

3. The inner wall friction coefficient is small, 0.0081-0.091, reducing energy consumption;

4. The inner wall meets the national health standards;

5. The inner wall is smooth and not easy to scale, with a self-cleaning function.
