DN400 high strength HDPE double-wall corrugated pipe

Detailed Product Description

    HDPE double-wall corrugated pipe is a kind of pipe made of high-density polyethylene (HDPE) with a unique double-wall structure, i.e., the inner and outer walls are connected with each other by corrugation. With unique structural design and excellent physical properties, this pipe is widely used in many fields such as municipal drainage, sewage, agricultural irrigation, construction engineering and communication engineering.

Corrugated Pipe Specification：

Corrugated Pipe Features：

• Unique structure, high strength: The outer wall is an annular corrugated structure, which greatly enhances the pipe's ring stiffness, thus increasing the pipe's resistance to soil loads, and in this performance aspect, HDPE double-wall corrugated pipe has obvious advantages compared with other pipes.
• Smooth inner wall, low friction resistance: Its smooth inner wall reduces the friction resistance of the fluid in the pipe and improves the overflow.
• Convenient connection and good sealing: It provides a variety of connection methods, such as socket connection, hot fusion connection, electric fusion connection and clamp connection, etc., which ensures that the joints are well sealed and leakage-free.
• Light weight, quick construction: Compared with traditional piping materials, HDPE double-wall corrugated pipe is lighter in weight, which is easy for transportation and construction, and reduces the construction difficulty and cost.
• Corrosion resistance, long service life: Polyethylene material has good resistance to acid and alkali corrosion, buried service life of more than 50 years.
• Environmental protection, non-toxic, recyclable: HDPE double wall corrugated pipe is made of green materials, non-toxic and harmless, in line with the requirements of sustainable development, and can be recycled and reused.
• Good low temperature resistance, impact resistance: HDPE double wall corrugated pipe embrittlement temperature is -70 ℃. General low-temperature conditions (-30 ℃ or more) construction without having to take special protective measures, winter construction is convenient, and, HDPE double-wall corrugated pipe has good impact resistance.
