Strong external pressure resistance
The outer wall is of annular corrugated structure, which greatly enhances the ring stiffness of pipes, thus enhancing the resistance of pipes to soil load. In this performance, HDPE double-wall corrugated pipes have obvious advantages compared with other pipes.
Low project cost
Under the condition of equal load, HDPE double-wall corrugated pipe only needs thinner pipe wall to meet the requirements. Therefore, compared with the solid-wall phase pipe with the same material specification, it can save about half of the raw materials, so the cost of HDPE double-wall corrugated pipe is also lower. This is another outstanding feature of the pipe.
Convenient construction
As HDPE double-wall corrugated pipe is light in weight and convenient in transportation and connection, it is fast in construction and simple in maintenance. Under the condition of tight construction period and poor construction conditions, its advantages are more obvious.
Low friction and high flow
HDPE double-wall corrugated pipe made of HDPE can pass through larger flow than other pipes with phase diameter. In other words, under the same flow requirements, HDPE double-wall bellows with relatively small caliber can be used. Good low temperature resistance and impact resistance: the brittle temperature of HDPE double-wall corrugated pipe is -70℃. In general, special protection measures need not be taken during construction at low temperature (above -30℃), which is convenient for construction in winter. Moreover, HDPE double-wall corrugated pipe has good impact resistance. Good chemical stability: HDPE has excellent chemical stability because it has no polarity. Except a few strong oxidants, most chemical media have no destructive effect on them. Generally, the soil, electricity, acid and alkali factors in the use environment will not destroy the pipeline, and will not breed bacteria and scale, and its circulation area will not decrease with the increase of operation time. Long service life: the service life of HDPE double-wall corrugated pipe can reach more than 50 years without sunlight and ultraviolet rays. Excellent wear resistance: Germany has used tests to prove that the wear resistance of HDPE is even several times higher than that of steel pipes. Appropriate flexibility: a certain length of HDPE double-wall corrugated pipe can be slightly flexed in the axial direction, which is not affected by uneven settlement of the ground to a certain extent, and can be directly laid in a slightly straight groove without pipe fittings, etc.
