HDPE double-wall corrugated pipes are flexible tubes. Their specifications are as follows:

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

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

Easy to install, due to the lightweight nature of HDPE double-walled corrugated pipes, transportation and connection are convenient, resulting in quick installation and simple maintenance work.

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

The脆ification temperature of the HDPE double-walled corrugated pipe is -70°C. Under normal low-temperature conditions (-30°C and above), no protective measures are required during construction, making winter construction convenient.
