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 resistance and operating temperature.

3. Low thermal conductivity.

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

5. Pipe connection uses electrofusion welding technology, which is mature, with a wide variety of pipe fittings.

6. Lightweight, easy to transport and construct.

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

8. Using high-temperature resistant plastics such as PE-RT, PP-R, etc., can manufacture pipes that are temperature and pressure resistant.

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

II. Product Application Fields

1. Chemical Industry: Process and discharge pipes for transporting corrosive gases, liquids, and solid powders in acid, alkali, salt manufacturing, petroleum industry, fertilizers, pesticides, pharmaceuticals, chemicals, mining, rubber, and plastics.
