Introduction to the eight advantages of HDPE double-wall corrugated pipe

HDPE double-wall corrugated pipe is made of HDPE as the main raw material. It is extruded from the inside and outside to form a smooth inner wall at one time. The outer wall is trapezoidal corrugated. There is a hollow plastic pipe between the inner and outer walls. Features are as follows:

1. Strong resistance to external pressure. The outer wall has a ring-shaped corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil loads. In this performance, HDPE double-wall corrugated pipe has obvious advantages compared with other pipes. The advantages.

2.  The project cost is low. Under the condition of equal load, HDPE double-wall corrugated pipe only needs a thinner pipe wall to meet the requirements. Therefore, compared with solid-wall pipes of the same material and specifications, it can save about half of the raw materials, so the cost of HDPE double-wall corrugated pipes is also lower. This is another outstanding feature of the pipe.

3.  Convenient construction Since the HDPE double-wall corrugated pipe is light in weight, it is easy to carry and connect, so the construction is quick and the maintenance is simple. In the case of tight construction period and poor construction conditions, its advantages are more obvious.

4.  The friction coefficient is small, the flow rate is large. HDPE double-wall corrugated pipe made of HDPE material can pass through a larger flow rate than other pipes of the same diameter. In other words, under the same flow requirements, HDPE double-wall corrugated pipes with a relatively small diameter can be used. Good low temperature resistance and impact resistance. The embrittlement temperature of HDPE double-wall corrugated pipe is -70℃. Under normal low temperature conditions (above -30℃), special protective measures are not necessary for construction. The construction is convenient in winter. In addition, HDPE double-wall corrugated pipe has good impact resistance.

5.  Good chemical stability Since HDPE molecules have no polarity, they have excellent chemical stability. Except for a few strong oxidants, most chemical media do not have destructive effects on it. The soil, electricity, acid and alkali factors of the general use environment will not damage the pipeline, will not breed bacteria, will not scale, and its circulation area will not decrease with the increase of operating time.

6.  Long service life. The service life of HDPE double-wall corrugated pipe can reach more than 50 years under the condition of not being exposed to sunlight and ultraviolet rays.

7.  Excellent wear resistance German tests have proved that the wear resistance of HDPE is even several times higher than that of steel pipes.

8.  Appropriate deflection. HDPE double-wall corrugated pipes of a certain length can be slightly deflected in the axial direction, and are not affected by a certain degree of uneven settlement on the ground. They can be directly laid in slightly uneven grooves without pipe fittings, etc. .
