Double-wall corrugated pipe is a lightweight pipe made from polyethylene, featuring light weight, good flexibility, and quick installation. Its wall structure design reduces costs compared to other pipe materials. Additionally, due to its ease of connection, it is widely used domestically and serves as a substitute for concrete pipes and cast iron pipes.

HDPE double-walled corrugated pipes are flexible tubes. Their properties include:

The outer wall features a ringed corrugated structure, enhancing the hoop stiffness of the pipe material and thereby increasing the pipeline's resistance to soil loads. In this performance aspect, HDPE double-walled corrugated pipes have more advantages compared to other pipe materials.

Under operating load conditions, HDPE double-wall corrugated pipes can meet requirements with thinner walls. Therefore, compared to solid-wall pipes of the same material and specification, they can save about half of the raw materials, which is another feature of this pipe material.

Easier installation due to the lightweight nature of HDPE double-wall corrugated pipes, which facilitate handling and connection, making the construction process quick and maintenance straightforward.

The HDPE double-wall corrugated pipe, made of HDPE material, has a smaller friction coefficient and can handle a larger flow rate than other materials of the same diameter. In other words, under the same flow rate requirement, a smaller-diameter HDPE double-wall corrugated pipe can be used.
