Ordinary Discount Extrusion Screw And Barrel - Plastic double wall corrugated pipe production line – SuperX

Product Description

The HDPE double wall corrugated pipe belong to the flexible pipe. Its performance is as follows:

Strong ability to resist external pressure
The outer wall is a ring corrugated structure, which greatly enhances the ring stiffness of the pipe, thus enhancing the resistance of the pipe to soil load. In this performance, HDPE double-wall bellows have obvious advantages compared with other pipes.

Low project cost
Under the condition of the same load, HDPE double wall bellows only need a thinner wall to meet the requirements. Therefore, compared with the solid wall tube with the same material specifications, it can save about half of the raw materials, so the cost of HDPE double-wall bellows is also lower. This is another outstanding feature of the tube.

Construction is convenient
Because the HDPE double-wall bellows are light in weight and convenient in handling and connection, the construction is quick and the maintenance is simple. In the construction period tight and

In the case of poor conditions, its advantage is more obvious.
Small coefficient of friction and large flow

HDPE double wall bellows made of HDPE can pass a greater flow rate than other pipes of the same caliber. In other words, the same flow requirements, can use a relatively small caliber HDPE double wall bellows.

Low temperature and impact resistance
The embrittlement temperature of HDPE double-wall bellows is -70℃. General low temperature conditions (above -30℃) do not need to take special protective measures when the construction, winter construction is convenient, and, HDPE double wall bellows have good impact resistance.

Good chemical stability
Because HDPE molecules have no polarity, they have excellent chemical stability. Except for a few strong oxidants, most chemical media can not destroy it. Soil, electricity, acid and alkali factors in the general use environment will not cause the pipeline damage, no bacteria, no scaling, and its circulation area will not decrease with the increase of operation time.

Long service life
The service life of HDPE’s double-wall bellows can reach more than 50 years in the absence of sunlight.

Excellent wear resistance
Germany has used tests to prove that the wear resistance of HDPE is even several times higher than that of steel pipe.

Proper deflection
A certain length of HDPE double-wall corrugated pipe bellow axial flexion can be slightly, not affected by a certain degree of uneven settlement on the ground, can be directly laid in a slightly not straight groove and so on.
