PE double wall corrugated pipe specifications and selection recommendations

PE double-wall corrugated pipe is a high-strength, corrosion-resistant pipe widely used in drainage, sewage, rainwater pipes and other fields. Its unique double-wall design provides excellent pressure resistance and long-term performance, and is suitable for municipal engineering, agricultural irrigation and other scenarios. The following are the specifications and selection suggestions of PE double-wall corrugated pipes to help you better choose the right pipe.

The common specifications of PE double-wall corrugated pipes vary according to the pipe diameter, ring stiffness and length

The common specifications are as follows

1. Pipe diameter

The common pipe diameter ranges from 110mm to 1200mm, which is suitable for different flow and discharge requirements.

2. Ring stiffness grade

It is usually divided into two types of ring stiffness, SN4 and SN8, which represent the compressive strength of the pipe. SN4 is suitable for laying under general conditions, while SN8 is suitable for environments with greater external pressure, such as areas with greater traffic loads.

3. Length

The standard length is 6 meters and 9 meters, which is easy to transport and install. Long pipes can reduce joints and enhance sealing.

Selection suggestions for PE double-wall corrugated pipes

1.Pipe diameter selection

Select the appropriate pipe diameter according to the drainage or sewage volume of the project. Small diameter pipes such as 110mm and 160mm are suitable for small drainage systems, while large diameter pipes such as 800mm and above are suitable for large projects such as municipal drainage and sewage treatment.

2. Ring stiffness grade selection

PE double-wall corrugated pipes often have two ring stiffnesses, SN4 and SN8. SN4 is suitable for laying under general soil conditions and is suitable for light load occasions; SN8 is suitable for high load occasions, such as under the road or industrial sewage system, and can withstand greater external pressure.

3. Length selection

According to the laying conditions and installation convenience of the construction site, choose a pipe length of 6 meters or 9 meters. Longer pipes reduce the number of joints, which helps to improve the sealing and stability of the pipe.

4. Corrosion resistance

Choose PE double-wall corrugated pipes with excellent corrosion resistance to ensure that the pipes are not affected by long-term use in harsh chemical environments.

5. Connection method

Use a socket connection method with good sealing to ensure the sealing and anti-leakage ability of the pipeline system.

Reasonable selection of specifications and ring stiffness according to engineering requirements can ensure the smooth progress of the project and achieve the best use effect.
