The composite of each layer is carried out in the molten state of plastic; It is completely different from the secondary melting and forming of wrapped tubes (hollow wall tubes), so the layers are completely bonded together, and the fastness is very high.

Special pre-treatment is carried out on the surface of the steel strip to enhance its anti-corrosion ability and the adhesion between steel and plastic, thereby improving its peel strength. The overall structure of the pipe is firm and reliable when wrapped in a fully melted plastic material. Due to the use of special materials and processes, both the anti-corrosion problem of steel plates and the adhesion between steel plates and PE materials have been solved, ensuring that the service life of pipelines is the same as that of pure plastic pipelines, with a guarantee of over 50 years.

It can be connected using electric heating fusion, heat shrinkable tape, internal and external extrusion welding, or a combination of multiple connections, ensuring a secure connection. Reliable connections can achieve zero leakage in pipelines.

Product features:

1. Chemical resistance: not corroded by pollution, wastewater, or chemicals, and not corroded by decaying substances in the soil.

2. Impact resistance: The pipe wall adopts a "U" - shaped structure, which is impact resistant, pressure resistant, and does not break even when the foundation sinks. Moreover, it has strong resilience after deformation and good adaptability to the foundation.

3. Aging resistance: The pipes are usually black and can withstand direct sunlight during storage and construction.

4. Cold resistance: The pipe will not freeze, crack, expand, or leak water in an environment of -60 ℃.

5. Lightweight: Easy to transport and construct, it is 1/8 the weight of cement pipes. The buried pipes only require an excavator and do not require large equipment.

6. Easy connection: The pipes can be graded outside the ditch and pushed into the ditch with an excavator, reducing construction time and cost.

7. Superior wear resistance: more wear-resistant than steel pipes and cement pipes, with strong ability to transport domestic water and waste.

8. Superior drainage flow: smooth interior, reduced friction, fast drainage speed.

9. Economy: Low construction, management, and maintenance costs.

10. Environmental impact: HDPE is a non-toxic raw material, harmless to the environment such as land, and can be recycled.

11. Good stability of pipeline system: The circular external reinforcement structure of the pipe not only increases the ring stiffness of the pipe, but also has a root resistance effect, solving the problems of tension and jacking caused by longitudinal displacement of the pipeline.

12. Completely reliable ring stiffness: Due to the elastic modulus ratio of steel and plastic materials being greater than 200 and the weight ratio being greater than 7.85, compared to pure plastic pipes, steel strip reinforcement can easily provide pipes (especially large-diameter pipes) with sufficient safe and reliable ring stiffness and relatively high stiffness to weight ratio.
