I. Product Performance

1. Has higher rigidity and impact resistance than plastic pipes, with low expansion coefficient and creep resistance similar to steel pipes.

2. Double-sided anti-corrosion, with the same anti-corrosion performance as plastic pipes, and improved corrosion resistanceandoperating temperature.

3. Low thermal conductivity.

4. Smooth inner wall, no scaling, head loss 30% lower than steel pipes.

5. Pipes are connected using electrothermal fusion, a mature technology with a wide variety of fittings.

6. Lightweight, easy to transport and install.

7. By adjusting the thickness of the steel plate and plastic, pipes of different pressure grades can be manufactured, and the parameters of the reinforcement can be easily modified to produce pipes of various pressure ratings.

8. Using plastics with high temperature resistance, such asPE-RT,PP-R, etc., pipes resistant to temperature and pressure can be manufactured.

9. High overall reliability, with a service life of up to 50 years under normal conditions.
