Product Description
Double-wall corrugated pipe is a new type of lightweight pipe made of high-density polyethylene. It has the characteristics of light weight, high pressure resistance, good toughness, fast construction and long service life. Its intentional wall structure design and other structures. Compared with pipes, the cost is greatly reduced. And because the connection is convenient and reliable, it is widely used at home and abroad. A large number of alternative concrete pipes and cast iron pipes.
HDPE corrugated pipes can be classified into S1 and S2 based on their ring stiffness.S1 corresponds to SN4, while S2 corresponds to SN8. The ring stiffness of SN4 is lower than that of SN8.The selection between S1 and S2 mainly depends on the following factors:
Pipe burial depth: The greater the burial depth, the higher the required ring stiffness.
Soil bearing capacity: The poorer the soil bearing capacity, the higher the required ring stiffness.
Pipe loading: The greater the load on the pipe, the higher the required ring stiffness.
Construction environment: The more complex the construction environment, the higher the requirements for the pipe.
1. Strong resistance to external pressure: the annular corrugated structure of the outer wall greatly enhances the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load. In this aspect, HDPE double-wall corrugated pipe has obvious advantages over other pipes.
2. Low project cost: under the same load condition, the HDPE double-wall bellows only need a thinner wall to meet the requirements.Therefore, compared with the solid wall tube of the same material specification, it can save about half of the raw material, so the cost of HDPE double wall bellows is also lower.This is another outstanding feature of the pipe.
3. Convenient construction: due to the light weight of HDPE double-wall corrugated pipe, it is convenient to carry and connect, so the construction is quick and the maintenance is simple.
4. Long service life: the service life of HDPE double-wall bellows can be more than 50 years under the condition of not being exposed to the sunlight and ultraviolet ray.

1. Municipal drainage and sewage pipeline system engineering;
2, apartment, residential area buried underground drainage sewage;
3. Expressway embedded pipeline and golf course underground seepage pipe network;
4. Water conservancy, irrigation, water transmission, drainage and other water conservancy projects;
5. Chemical industry and mine are used for fluid transportation and ventilation, etc.;
6. Protective sleeve of underground pipeline and communication cable.
The connection method is melt welding connection, which is also the most commonly used connection method for ordinary construction workers.With electric fusion connection or hot melt connection joint , the effect of the connection are safe and reliable.
We can ship the pipes by sea in 20/40 GP container ,we can also ship pipes by train or truck,fitting will be packing by cartons.
