Perforated steel strip PE composite pipes for cold water, perforated steel strip PE-RT composite pipes for hot fluids

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 excellent corrosion resistance. Operating temperature is increased.

3. Low thermal conductivity.

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

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

8. Using high-temperature-resistant plastics, such as heat-resistant PE-RT, random copolymer polypropylene (PP-R), etc., temperature and pressure-resistant pipes can be manufactured.

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