Product Introduction of HDPE Hollow Wall Spiral Pipe
The HDPE hollow-wall spiral-wound pipe is made from PE100 material and is supported by a special winding molding process. Its unique structure endows it with features such as light weight, high strength and corrosion resistance. It is widely used in municipal drainage, sewage treatment, and underground pipeline systems that do not bear pressure.
Product structure features
1.The inner wall is smooth.
- The inner wall of the product is made of HDPE solid-walled pipes.
- The inner surface is smooth, which can effectively enhance the flow efficiency of the fluid.
2.The spiral-wound outer structure.
- The outer layer is formed by winding a hollow circular structure.
- Make the product have high ring stiffness.
- This effectively enhances the material's resistance to external pressure, thus enabling the product to be installed underground
3.The middle layer has a reinforcement structure.
- The hollow structure ensures the lightweight of the product, while also maintaining its strength.
- The product ring stiffness can be adjusted according to specific requirements, ranging from SN4 to SN16.
Product Advantages
1. Strong pressure resistance
- The structured design gives the pipeline high hoop stiffness.
- Capable of withstanding the pressure of the soil layer and the load of vehicles
- Often used in deep-buried or soft soil foundation projects
2. Corrosion-resistant and long-lasting
- HDPE is itself stable in acidic, alkaline and salt media.
- Will not rust or corrode
- The normal service life can exceed 50 years.
3. Lightweight and easy to install
- It is much lighter than traditional cement pipes and cast iron pipes.
- Easy transportation and high construction efficiency
- It can be welded on-site, reducing the number of interfaces.
4. The connection method is reliable.
- The following connection methods can be adopted: electrofusion welding, heat shrinkable tape connection, and socket and plug rubber ring connection.
- The connection has good sealing performance and is not prone to leakage.
5. Smooth inner wall, low fluid resistance
- The flow capacity is higher than that of the conventional concrete pipe.
- Not prone to scaling, reducing maintenance costs
Application fields
Municipal drainage and sewage projects, industrial drainage and sewage pipelines, sponge city water storage and drainage system.
