HDPE double-wall corrugated pipe has excellent chemical stability, aging resistance and environmental stress crack resistance. The HDPE double-wall corrugated pipe produced from the raw material is a flexible pipe. Its performance is as follows:

1. Strong resistance to external pressure: the outer wall has an annular corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil load. In this performance, the use of HDPE double-wall corrugated pipe and PE pipe, Compared with other pipes, it has obvious advantages.

2, the project cost is low: under the conditions of equal load, the use of PE pipe, HDPE double-wall corrugated pipe only needs a thinner pipe wall to meet the requirements. Therefore, compared with the solid wall tube of the same material specification, it can save about half of the raw materials, so the HDPE double-wall corrugated pipe is also low in cost. This is another outstanding feature of the pipe.

3. Convenient construction: Because HDPE double-wall corrugated pipe is light in weight, it is convenient to carry and connect, so the construction is quick and the maintenance work is simple. The advantages are even more obvious when the construction period is tight and the construction conditions are poor.

4. The friction coefficient is small and the flow rate is large: HDPE double-wall corrugated pipe made of HDPE can pass more flow than other pipes of phase diameter. In other words, with the same flow requirements, a relatively small diameter HDPE tube can be used.

5, good low temperature resistance, impact resistance: HDPE double wall corrugated tube embrittlement temperature is -70 ° C. Under normal low temperature conditions (above -30 °C), special protection measures are not required, and construction in winter is convenient. Moreover, HDPE double-wall corrugated pipes have good impact resistance.

6. Good chemical stability: Since HDPE molecules have no polarity, the chemical stability is excellent. With the exception of a few strong oxidants, most chemical media do not destructively. The soil, electricity, acid and alkali factors of the general use environment will not destroy the pipeline, no bacteria, no scaling, and the circulation area will not decrease with the increase of running time.

7. Long service life: HDPE double-wall corrugated pipe can be used for more than 50 years without being exposed to sunlight and ultraviolet rays.

8, excellent wear resistance: Germany has used tests to prove that the use of PE pipe, HDPE wear resistance is even several times higher than steel pipe.

9. Appropriate deflection: The length of the HDPE double-wall corrugated pipe can be slightly deflected. The use of the PE pipe is not affected by the uneven settlement of the ground to a certain extent. It can be directly laid in the pipe without the pipe fitting. Inside the groove and so on.
