I. Product Performance

1. High rigidity and impact resistance exceeding that of 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 resistance and operating temperature.

3. Low thermal conductivity.

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

5. Pipes are connected using electrofusion, 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, allowing easy modification of reinforcement parameters to produce pipes of various pressure ratings.

8. Using high-temperature resistant plastics, such as PE-RT, PP-R, etc., pipes resistant to high temperature and pressure can be produced.

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

II. Product Application Areas
