Hebei full 400 # large diameter sewage, good quality, corrosion-resistant

HDPE large diameter outfall performance 1, against external pressure and strong outer annular corrugated structure, greatly enhancing the pipe ring stiffness, thus increasing the resistance of the soil pipe load, in this performance, HDPE double-wall bellows Compared to other pipe has obvious advantages. 2, low construction cost in wait for the next load conditions, HDPE double wall corrugated pipe requires only a thin wall to meet the requirements. Thus, with the same material specifications than solid wall of the tube, you can save about half of the raw material, so HDPE double wall corrugated pipe cost is lower. This is another very prominent characteristics of the pipe. 3, the construction is convenient because of its light weight HDPE double wall corrugated pipe, handling and connection easy, so fast construction, maintenance simple. In the tight schedule and construction conditions poor situation, its advantage is more obvious. 4, the friction coefficient is small, flow of materials using HDPE double wall corrugated HDPE pipe with diameter pipe than the other by more traffic. In other words, the same flow requirements, can be relatively small caliber double-wall corrugated HDPE pipe. Good low temperature impact resistance: brittle temperature HDPE double wall corrugated pipe is -70 ℃. In general, low temperature (above -30 ℃) does not have to take special protective measures during construction, winter construction is convenient, but, HDPE double wall corrugated pipe has a good impact resistance. Good chemical stability: Because no HDPE molecular polarity, excellent chemical stability. Apart from a few strong oxidant, most of them can not afford to undermine the role of chemical mediators. Soil general use of the environment, electricity, acid factor will not damage the pipeline, no bacteria, no scaling, its circulation area will not increase over time and reduce run. Long life: Under ultraviolet light from the sun conditions, HDPE double wall corrugated pipe service life of up to 50 years. Excellent wear resistance: Germany had used tests proved, HDPE wear even several times higher than steel. Appropriate deflection: HDPE double wall corrugated pipe axial length may be slightly deflected from the ground to a certain extent of uneven settlement, it can not pipe laid directly in the trenches, and so slightly not straight.
