HDPE Double Wall Corrugated Pipe

Description

Description  of HDPE Double Wall Corrugated Pipe

HDPE double wall corrugated pipe is a new type of lightweight pipe, which made of high-density polyethylene as the main raw material, extruded from the inside and outside, and formed in one time. The inner wall is smooth and flat, the outer wall is trapezoidal corrugated, and there is a hollow layer between the inner and outer wall. Its unique pipe wall structure design makes this type of pipe have the characteristics of large ring stiffness, light weight, high pressure resistance, good toughness, and corrosion resistance. It can be laid on where poor geology, and has good sealing and quick construction performance.

Advantages of HDPE Double Wall Corrugated Pipe

1、Strong pressure resistance: The outer wall has an annular corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the pipe’s resistance to soil load.

2、Low project cost: Under the same load conditions, HDPE double-wall corrugated pipes only need thinner pipe walls to meet the requirements.

3、Convenient construction: Since HDPE double-wall corrugated pipes are light in weight, they are easy to carry and connect, so construction is fast and maintenance is simple.

4、Small friction coefficient and large flow rate: HDPE double-wall corrugated pipes made of HDPE can pass a larger flow rate than other pipes of the same caliber.

5、Low temperature and impact resistance: The brittle temperature of HDPE double-wall corrugated pipes is -70℃. Under normal low temperature conditions (above -30℃), no special protective measures are required during construction, and winter construction is convenient. Moreover, HDPE double-wall corrugated pipes have good impact resistance.

6、Good chemical stability: The soil, electricity, acid and alkali factors in the general use environment will not damage the pipeline, will not breed bacteria, will not scaling, and its flow area will not decrease with the increase of operating time.

7、Long service life: Under the condition of not being exposed to sunlight ultraviolet rays, the service life of HDPE double-wall corrugated pipe can reach more than 50 years.

8、Excellent wear resistance: The wear resistance is higher than that of steel pipe.

9、Appropriate deflection: A certain length of HDPE double-wall corrugated pipe can be slightly deflected in the axial direction, and is not affected by a certain degree of uneven settlement of the ground. It can be laid directly in a slightly crooked groove without pipe fittings, etc.
