HDPE hollow double wall winding pipe

Characteristics of HDPE steel strip wrapped pipe

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 resistant to impact and pressure, 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 connected outside the ditch and pushed into the ditch with an excavator, reducing project 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 residue;

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 plastic materials being greater than 200 and the weight ratio being greater than 7.85, compared to pure plastic pipes, steel strip reinforcement makes it easy for pipes (especially large-diameter pipes) to have sufficient safe and reliable ring stiffness and relatively high stiffness to weight ratio
