High density polyethylene (HDPE) has excellent chemical stability, aging resistance and environmental stress cracking resistance. The HDPE double-wall corrugated pipe is a flexible pipe. Its main performance is as follows:
Strong resistance to external pressure
The outer layer 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.
Low project cost
Under the same load condition, HDPE double-wall corrugated pipe only needs a thinner pipe thickness 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.
Convenient construction
As HDPE double-wall corrugated pipes are light in weight and easy to carry and connect, 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.
Small friction coefficient, large flow
HDPE double-wall corrugated pipe have 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.
Low temperature 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. HDPE double-wall corrugated pipe has good impact resistance.
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 a destructive effect on it. The soil, electricity, and acid-base 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.
Long use life
The 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.
Excellent wear resistance
Tests in Germany have proved that the wear resistance of HDPE is higher than that of steel pipes.
Proper 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 on the ground. It can be directly laid in a slightly uneven groove without pipe fittings.
