Product Overview

The U-shaped steel strip composite PE material is used, so that the pipe can greatly improve the ring stiffness without increasing the cost, and the strength of the pipe is greatly improved compared with the winding pipe and carat pipe under the same weight. It can solve a series of problems such as heavy load, and the advantages of large-diameter pipes are more obvious, and the diameter of the production pipes is from DN300mm to DN2400mm, and the ring stiffness is maintained above 8KN/m2, which is lighter in weight and higher in strength than cement pipes and other plastic pipes.

The lamination of the layers is carried out in the molten state of the plastic; It is completely different from the secondary melting of spiral wound pipes (hollow-walled pipes), so the layers are completely bonded to each other and have a very high fastness.

The surface of the steel strip is specially pre-treated to enhance the anti-corrosion ability of the steel and the adhesion of the steel and plastic, and improve the peel strength. It is wound and formed in the state of full melting of plastic raw materials, and the overall structure of the pipe is firm and reliable. Due to the use of special materials and processes, it not only solves the problem of anti-corrosion of steel plates, but also solves the adhesion between steel plates and PE materials, so that the service life of the pipeline is the same as that of pure plastic pipes, which is guaranteed to be more than 50 years.

Product performance

1. Chemical resistance: not corroded by pollution, wastewater and 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 and pressure-resistant, and does not break in the case of foundation sinking, and has strong resilience after deformation, and has good adaptability to the foundation;

3. Aging resistance: the pipe is usually black, which can withstand direct sunlight during storage and construction;

4. Cold resistance: the pipe will not be frozen and cracked, expanded and leaked in the environment of -60°C;

5. Light weight: easy to transport, convenient construction, is 1/8 of the weight of the cement pipe, and the buried pipe only needs an excavator, no large equipment;

6. Easy connection: the pipe can be connected outside the ditch first, and pushed into the ditch with an excavator to reduce the engineering time and cost;

7. Superior wear resistance: more wear-resistant than steel pipes and cement pipes, and strong transportation capacity of domestic water waste residue;

8. Superior drainage circulation: smooth inside, reduce friction, and fast drainage speed;

9. Economy: low cost of construction, management and maintenance;

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

11. Good stability of pipeline system: The circular outer rib structure of the pipe not only increases the ring stiffness of the pipe, but also has the effect of root resistance, which solves the tension and top well problems caused by the longitudinal displacement of the pipeline.

12. Completely reliable ring stiffness: because the elastic modulus ratio of the two materials is greater than 200 and the weight ratio is greater than 7.85, compared with pure plastic pipes, steel belt reinforcement is easy to make pipes (especially large-diameter pipes) have sufficient safe and reliable ring stiffness and relatively high stiffness-to-weight ratio
