Over 20 years of R&D and manufacturing of perforated steel strip polyethylene composite pipes

1) For Cold Water Use Perforated Steel Strip Polyethylene Composite Pipe

The perforated steel strip polyethylene composite pipe is a composite pipe that uses a cold-rolled steel strip welded perforated pipe as the reinforcing skeleton and is combined with thermoplastic plastic. Due to the introduction of the reinforcing skeleton, the heat resistance and strength of the pipe are significantly improved. In terms of process, this product introduces an adhesive layer between the steel strip and polyethylene, and uses argon protection during steel strip welding to prevent oxidation of the molten steel during high-temperature welding, solving the water leakage problem of composite pipes and making the performance of the composite pipe even better.

1. Has higher rigidity, impact resistance than plastic pipes, and has a 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 is corrosion-resistant. 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. Pipe connection uses electrothermal fusion connection, with mature technology and a wide variety of pipe fittings.

6. Lightweight, easy to transport and construct.

7. By adjusting the thickness of the steel plate and plastic, pipes of different pressure grades can be manufactured, and it is very convenient to change the parameters of the reinforcement to produce pipes of various pressure resistance levels.

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

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

2. Perforated Steel Strip Heat-Resistant Polyethylene (PE-RT) Composite Pipe for Hot Fluids (Dongtai Pipe Industry)

This product is composed of a cold-rolled perforated steel strip welded perforated pipe as the reinforcing skeleton and heat-resistant polyethylene (PE-RT) as the main material. Due to the introduction of the reinforcing skeleton and heat-resistant polyethylene (PE-RT), the pressure resistance and heat resistance of the pipe are significantly improved. This allows composite pipes originally only suitable for low-temperature (≤40°C) water supply to be used for hot water transportation, secondary heating pipelines, and industrial fields such as chemical and pharmaceutical industries for transporting high-temperature media.
