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

HDPE double-wall corrugated pipe is a flexible pipe. Its properties are as follows:

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

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

Easy to install; due to the lightweight nature of HDPE double-wall corrugated pipes, transportation and connection are convenient, making installation quick and maintenance simple.

The HDPE double-walled 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 requirements, a smaller diameter HDPE double-walled corrugated pipe can be used.

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