Corrugated High Density Polyethylene Pipe

Corrugated high density polyethylene pipe is a double-wall corrugated pipe with different inner and outer wall structures. The outer wall has a continuous corrugated structure to enhance the ring stiffness of the pipe; the inner wall remains smooth to reduce water flow resistance.

Corrugated High Density Polyethylene Pipe Manufacturer in China

Corrugated high density polyethylene pipe is a high-performance plastic pipe widely used in municipal drainage, sewage, agricultural irrigation, cable protection and other fields. It is made of high-density polyethylene (HDPE) material, with an outer corrugated structure and an inner smooth structure, and has good mechanical properties and flow capacity.

HUALIN Corrugated High Density Polyethylene Pipe Applications Explored

High-density corrugated polyethylene pipes play a key role in many fields with their excellent physical properties and chemical stability. In municipal engineering, as the core pipe material of urban rainwater and sewage pipe networks, it can withstand heavy road loads and soil pressure with its high ring stiffness, prevent pipe deformation and rupture, and ensure the efficient operation of the drainage system; in water conservancy and irrigation, it can be used for long-distance water transmission and farmland drip irrigation pipe network laying. Its low temperature resistance and anti-aging properties enable it to adapt to complex climatic conditions and ensure the stable transportation of water resources; in the power and communications industries, high-density corrugated polyethylene pipes are often used as cable protection sleeves to resist threats such as construction excavation and soil acid and alkali corrosion, providing safety protection for power transmission and communication signals; in the industrial field, for harsh scenarios such as corrosive wastewater discharge from chemical companies and mine tailings transportation, its super chemical corrosion resistance effectively extends the service life of the pipe; in addition, in environmental protection projects such as landfill leachate collection and sewage treatment plant drainage systems, the advantages of the pipe’s non-toxic, environmentally friendly and good sealing can not only avoid pollution leakage, but also adapt to foundation settlement, making it a reliable choice for green engineering construction.

FAQ

How to install high density corrugated polyethylene pipe?

The following is the standard installation method for corrugated polyethylene pipes
1.Pipe inspection
Check the appearance of each pipe (no pits, cracks), dimensional tolerance and sealing ring integrity. Unqualified products are prohibited.
2.Trench excavation and foundation treatment
Excavate according to the designed route. The trench width must be 20-30cm larger than the pipe diameter; the bottom of the trench must be flat and free of stones, and a 15cm sand cushion layer must be laid and compacted.
3.Pipeline laying and connection
Use alcohol or water to remove the sand and oil stains on the inner wall of the socket and ensure dryness. The rubber sealing ring is placed in the groove between the second and third wave peaks of the socket. The number of installations is based on design requirements
4.Electric hot melt connection
Remove impurities from the heating wire area, fix the socket with a steel belt, set the temperature according to the equipment parameters, and cool naturally for ≥15 minutes.
5.Pipeline cutting and repair
When adjusting the length, vertical sawing and grinding of the section are required. Local damage can be repaired with a hot air gun and welding rods.
6.Backfill and acceptance
The first layer is covered with fine sand or soft soil ≥30cm from the top of the pipe, and compacted manually; the thickness of each subsequent layer is ≤20cm, and the mechanical compaction distance is >50cm from the top of the pipe. Sealing test: inject water into the closed pipe section and check if there is any leakage at the interface
