Huifeng Hollow Wall Pipe
The hollow wall wound pipe is a structural wall pipe made of high-density polyethylene (D) as raw material using a hot winding molding process. The pipe is suitable for municipal drainage where the water temperature is below ℃. , building outdoor drainage, buried farmland drainage, industrial sewage, road drainage, sewage treatment plant, sports field square engineering drainage and electrical and telecommunications engineering, etc. Since the hollow wall winding pipe is a chemical building material, it is of great significance to save energy, reduce pollution and protect the environment.
Excellent features:
The special-shaped structural profiles extruded from the die of the extruder are evenly wound around the drum mold at a predetermined position and the molten material is simultaneously extruded to weld the special-shaped structural profiles into a whole to ensure the structure. Wall pipe weld joint quality. High quality of weld seam
The pipeline adopts electric heating melt tape or heat shrink tape connection technology for construction, fast connection quality and high joint strength to ensure the unity of the interface material, structure and pipe body itself. Compared with rubber ring joints or other mechanical joints There is no risk of leakage from the joints. At the same time, because this product is lighter than other pipes under the same application conditions, it is easy to transport and construct, which can reduce construction costs. In the application, there is no need for concrete cushion and concrete pipe foundation trench. Once the trench is qualified, the pipe can be laid directly. Excavation, pipe running and backfilling can be done at the same time, which simplifies the construction procedure and shortens the construction period. ． Excellent installation performance, simple connection, reasonable, safe and reliable joint sealing form
D is a high molecular polymer, which makes the hollow wall wound pipe have good flexibility and overall ability to withstand external pressure. It can ensure traffic safety when used on roads with over-heavy loads. . Due to the flexibility of the pipe, pipe damage can be minimized when earthquakes, uneven ground settlement and other geological activities occur, which improves the ability of public facilities to resist earthquakes and reduce disasters. It has good flexibility and anti-seismic properties
The pipe is formed by winding process, which improves the ring stiffness of the pipe while saving material. High ring stiffness
High-density polyethylene has extremely strong resistance to corrosion and chemical erosion, and does not require any anti-corrosion treatment when transporting corrosive fluids or laying in highly corrosive soil. Other pipes. Due to its excellent aging resistance, its use as a buried pipeline can ensure a service life of 10 years. Strong resistance to chemicals and aging
High-density polyethylene winding structural wall pipes do not add any additives during processing. High-density polyethylene is used, has no toxicity, does not scale, and does not breed microorganisms. During the production process of the product, cooling water is recycled and no pollutants are produced to the environment. Waste pipes of the same brand can be recycled and reused. Good hygienic performance
The inner wall roughness of the hollow wall wound pipe is about 1. Therefore, the specific friction resistance when transporting fluid is small, and the water delivery capacity can be greatly increased compared with cement pipes under the same conditions of use. Therefore, the hollow wall winding pipe with a smaller inner diameter can be used to replace the cement pipe with a larger inner diameter, thereby reducing the project cost. The inner wall roughness of the pipe is low and the water transport capacity is large. The reliability of the hollow wall winding pipe project will be significantly improved compared with traditional pipes under the same conditions in the application, especially in narrow construction sites, dense buildings, complex underground pipelines and traffic. It is more advantageous in busy road sections and when paving in acidic and alkaline soils.
