Product Overview

Hollow wall winding pipe, English name Coil pipe, large-diameter winding pipe, double-wall winding pipe, hollow winding pipe is a kind of pipe formed by winding and welding with high-density polyethylene (HDPE) as raw material, due to its unique molding process, it can produce pipes with a diameter of up to 3 meters, which is difficult to complete by other production processes. High-density polyethylene (HDPE) not only ensures the product forming process and product quality due to its excellent melting and welding performance, but also provides a variety of reliable ways for construction connections, such as electric hot melt welding, heat shrinkable connection, etc., at the same time, this is also an important reason why leakage rarely occurs, and it is precisely because of this reason that this pipe has a unique environmental protection function that other pipes do not have, which provides a very effective method for the prevention and control of pollution that people are concerned about at present. In recent years, it has also been widely used in plastic inspection wells.

Product performance

1. Large caliber and many varieties. Polyethylene hollow wall winding pipe inner diameter 300mm-1600 is used in different projects.

2. Light weight. It is significantly lower than the weight of concrete pipes, which is convenient for transportation.

3. Good mechanical properties and high strength. The pipe wall adopts an "I-shaped" structure, which has excellent stamping resistance, external load resistance, and good material toughness. After the action of external force, the deformation recovery is strong, the product has excellent anti-settlement resistance, and has good adaptability to any foundation.

4. Excellent cold resistance and aging resistance. The pipes are usually black and can withstand direct sunlight during storage and construction, and will not be frozen and swelled in low temperature environments, causing leakage.

5. It has good chemical resistance. It is not corroded by sewage, waste water and chemicals, and is not corroded by corrosives in the soil.

6. The friction coefficient of the material is small and the wear resistance is excellent. It is more wear-resistant than steel pipes and concrete, and has a strong transportation capacity of domestic water waste residue.

7. Reliable connection and convenient construction. It is fast and convenient to connect by welding method. The buried pipe can be connected outside the ditch first, and then placed in the trench, which can reduce the required engineering time and cost, and the cost of engineering construction, management and maintenance is low.

8. Polyethylene is a non-toxic raw material and has no impact on the environment.
