HDPE Double Wall Corrugated Pipe

HDPE Double Wall Corrugated Pipe

HDPE double-wall corrugated (large-diameter sewage) pipe is made of high-density polyethylene as the main raw material. It is co-extruded by the inner and outer extruders and formed at one time. There is a hollow core layer between the walls, a unique structure, and a new type of plastic pipe with high strength. The complete production process is: Extrusion - Composite - Forming - Cooling - Cutting - Finished product.

Scope of Application:

◎ Sewage and drainage pipes: such as municipal engineering drainage, factories, enterprises, chemical industry, pharmaceutical industry drainage pipes.

◎ Various building drainage projects and supporting drainage projects: such as stadiums, railways, expressways, etc.

◎ Low-pressure water delivery projects: such as irrigation and drainage of farmland, orchards, and forestry.

◎ Ventilation and communication engineering: such as mine ventilation, mine wall permeation pipes, railway and highway cables, telecommunications, sheathing pipes.

Hdpe Pipe Features:

◎ The product has the advantages of light weight, high ring rigidity, convenient construction, transportation and installation, low installation cost, high anti-ultraviolet stability, good bendability, appropriate deflection, and fixed length. The shaft of HDPE double-wall corrugated pipe can be slightly deflected. The foundation will settle unevenly during use, and the pipe will bend naturally without causing leakage. The inner wall of the pipe is smooth, so the flow rate is larger compared with pipes of the same specification. Maintenance, pressure resistance, low temperature resistance, high impact strength, acid and alkali resistance, corrosion resistance, long service life and other characteristics.

◎ Reasonable structure and excellent performance: The double-wall corrugated pipe adopts ring-shaped wall pipe and optimized corrugated structure, so that the pipe has greater strength and proper flexibility per unit weight, so that the raw material can play a more efficient role. After years of production and practical application, the production technology is reliable and the product performance is stable.

◎ Reliable connection; prevent leakage: the double-wall corrugated pipe adopts the reinforced design of the socket, and the pipe interface is connected by neoprene and synthetic rubber elastic rubber sealing ring with acid, alkali and sewage corrosion resistance, which makes the pipe more firm and reliable before and after connection , The strict control of the size of the socket connection makes the construction more convenient and effectively prevents leakage.
