Product Features

1. Non-toxic HDPE, excellent impact resistance, compressive strength, and chemical corrosion resistance.

2. Weathering resistance: Pipes are usually black and can withstand sun exposure during storage and construction.

3. Excellent wear resistance: More wear-resistant than steel pipes and cement pipes, fast drainage, and large flow rate.

4. Customizable length according to customer requirements, reducing the number of pipe connections and avoiding environmental pollution caused by sewage leakage.

5. Connection methods: Heat shrink sleeve, electrothermal fusion tape, Hafu tape, rubber ring socket, electrofusion socket.

6. Arbitrary pipe length and advanced electrothermal fusion flexible connection allow the pipeline to adapt to various geological conditions without leakage.

7. Compared with traditional cement pipes, it saves construction costs and most foundation costs, making the comprehensive cost lower than that of traditional cement pipes.

Performance Characteristics
(1) High weld quality: The extruded profile is uniformly wound around the roller mold at predetermined positions, and PE melt is extruded synchronously to weld the profile into a whole, ensuring the quality of the weld seam of the structural wall pipe.

(2) Excellent installation performance, simple connection, reasonable and reliable joint sealing.
(3) Good flexibility and seismic performance: HDPE is a high molecular polymer, giving the hollow wall spiral pipe good flexibility and overall resistance to external pressure. It can ensure safe passage under roads with heavy loads.
(4) High ring stiffness: The pipe is formed by winding technology, which improves the ring stiffness of the pipe while saving materials.
(5) Strong chemical resistance and aging resistance, long service life. High-density PE has extremely strong corrosion resistance and resistance to chemical erosion. No anti-corrosion treatment is required when transporting corrosive fluids or laying in highly corrosive soil. Its performance is far superior to other pipe materials.
(6) Good hygiene performance. High-density PE spiral structural wall pipes do not add any auxiliaries during processing. 100% high-density PE is non-toxic, non-scaling, and does not breed microorganisms. It is pollution-free, recyclable, and environmentally friendly.
(7) Low inner wall roughness, large water transmission capacity: The inner wall roughness N of the hollow wall spiral pipe is about 0.010, so the frictional resistance is small when transporting fluids. Under the same conditions, the water transmission capacity is significantly higher than that of cement pipes, reducing engineering costs.
(8) Under the same application conditions, the hollow wall spiral pipe is lighter than other pipe materials, easy to transport, and convenient and quick construction, which can reduce construction costs. In application, no concrete cushion layer and concrete pipe base are required. The pipe can be laid directly after the trench is qualified. It can be excavated, laid, and backfilled at the same time, simplifying the construction process and shortening the construction period.

Application Range

This pipe is suitable for conveying water with a temperature below 45℃ for municipal drainage, building outdoor drainage, buried farmland drainage, industrial sewage discharge, road drainage, sewage treatment plants, sports field square drainage, and electrical and telecommunications engineering. Since HDPE hollow wall spiral pipes are chemical building materials, they are of great significance to energy saving, pollution reduction, and environmental protection.
