HDPE double-wall corrugated pipe with excellent chemical stability, resistance to aging and performance.

Strong ability to resist external pressure

The outer wall is annular corrugated structure, greatly enhance the pipe ring stiffness, thus enhances the pipeline on the soil load resistance, in terms of the performance, HDPE double-wall corrugated pipe compared with other pipe has obvious advantages.

The project cost is low

In the load conditions, such as HDPE double-wall corrugated pipe only need thinner wall can meet the requirements.Therefore, compared with the same material specifications of the solid wall pipe, can save about half of raw materials, so the HDPE double-wall corrugated pipe is low.This is again a very prominent characteristics of the pipe.

Construction is convenient

Because of the HDPE double-wall corrugated pipe light weight, handling and connection is very convenient, so the construction of efficient, simple maintenance.In the construction period and construction

The situation of the poor condition, its advantage is more obvious.

Friction coefficient is small, large flow

Using HDPE as material of HDPE double-wall corrugated pipe other pipes can be greater than the diameter of flow.In other words, under the same flow requirements, can use HDPE double-wall corrugated pipe diameter is relatively small.

Good low temperature resistance, impact resistant performance

HDPE double-wall corrugated pipe is the embrittlement temperature to 70 ℃.The condition of low temperature (more than 30 ℃) don't need to take special protective measures during the construction, the winter construction is convenient, and HDPE double-wall corrugated pipe has a good impact resistance.

Good chemical stability

Because the HDPE molecule no polarity, so excellent chemical stability.Except a few strong oxidizer, most chemical medium can't afford to damage to it.Generally use environment, electric power, acid and alkali soil factors will not make the pipeline damage, do not breed bacteria, not scale, its circulation area will not reduce with the increase of running time.

The service life is long

Under the condition of from the sun ultraviolet ray, HDPE double-wall corrugated pipe of use fixed number of year can reach more than 50 years.

Excellent wear resistance

Germany used test showed that the wear resistance of HDPE or even several times higher than steel pipe.

Appropriate deflection

A certain length of HDPE double-wall corrugated pipe axis can be slightly deflection, not affected by a certain degree of uneven settlement of the ground, do not need spread directly in slightly not straight pipe inside the groove, and so on.
