The characteristics of
HDPE double-wall corrugated pipe with excellent chemical stability, resistance to aging and environmental stress cracking resistance. For raw materials produced by the HDPE double-wall corrugated pipe belongs to the flexible pipe. Its performance is as follows:
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 cost of 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 °C. The condition of low temperature (more than 30 °C) 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.
1, unique structure, resistance to external pressure high strength, impact resistance, with a ring of flexible, smooth inner wall friction small, equal diameter pipe through the larger flow; Socket interface, flexible connection, convenient connection, high reliability, is not easy to leak.
2, light weight, quick construction, reduce the cost.
3, buried service life of more than 50 years.
Hdpe corrugated pipe
4, belongs to hydrocarbon polymer polyethylene, molecular non-polarity, naisuanjian corrosion.
5, raw materials for the green environmental protection material, non-toxic, no corrosion, no scaling, can be recycled.
6, suitable temperature range wide, pipeline rupture, 60 °C environment medium maximum temperature of 60 °C.
7 basic quite, comprehensive construction cost and concrete, low operating costs.
8, the soil under the condition of good without foundation.
2 application editor 1, municipal drainage, drainage pipe system engineering;
2, apartments, residential area underground buried sewage drainage;
3, highway embedded pipe, golf course underground water seepage pipe network;
4, irrigation and water conservancy irrigation water, drainage, water conservancy project;
5, chemical industry, mining for fluid conveying and ventilation, etc.;
6, the protection of underground pipeline and communication cable to protect casing pipe, etc.
3 storage method to edit the HDPE double-wall corrugated pipe should be stored interesting dry in the library. Straight pipe should be flat, stacking height should not exceed 2 m. Off and perforated pipe can be flat in coil, but should avoid stress or extrusion piled up.
HDPE double-wall corrugated pipe is not allowed and mixed with poisonous and harmful material, should be far away from the heat source, in the place shall set up eye-catching fire sign.
Storage period from the date of production, generally no more than 2 years.
4 transportation mode editing HDPE double-wall corrugated pipe can be used all kinds of transport vehicles.
Transportation, loading and unloading process, do not allow the throws, impact, pressure, long time exposure, or close to the heat source. Don't allow during with toxic and harmful substances. Into the disk flat transport perforated pipe.
