High-density polyethylene (HDPE) has excellent chemical stability, resistance to aging and environmental stress cracking resistance properties. Raw materials produced by HDPE double wall corrugated pipe belonging to the flexible pipe. The main properties are as follows: 1, compressive strength strong annular wall corrugated structure, greatly enhancing the pipe ring stiffness, thus increasing the resistance of the soil pipe load, in this performance, HDP giant double-wall corrugated pipe and other pipes comparison has obvious advantages. 2, low cost in wait for the next load conditions, HDPE double wall corrugated pipe only needs to meet the requirements of a thin wall. Thus, with the same material specifications than the real wall of the tube, can save about half of the raw materials, so the cost of HDPE double wall corrugated pipe is lower. This is another very prominent features of the pipe. 3, easy installation due to the light weight of HDPE double wall corrugated pipe, handling and connections are very convenient, so quick construction, maintenance simple. Under tight schedule bad conditions and construction conditions, the advantage is more obvious. 4, the friction is small, flow of materials using HDPE HDPE double wall corrugated pipe the same diameter pipe than the other by a greater flow. In other words, the same flow requirements, can be relatively small caliber double-wall corrugated HDPE pipe. 5, low temperature impact resistant HDPE double wall corrugated pipe brittle temperature is -70 ℃. Under normal low temperature conditions (above -30 ℃) do not have to take special protective measures during construction, winter construction is convenient, but, HDPE double wall corrugated pipe has good impact resistance. 6, chemical stability due to the HDPE molecules no polarity, so excellent chemical stability. Apart from a few strong oxidant, most can not afford to destroy its chemical media role. Soil environment in general use, electricity, pH factor of the pipeline will not cause damage, no bacteria, no scaling, its circulation area does not decrease with the increase of the running time. 7, weather resistance, long life under ultraviolet light from the sun conditions, HDPE double wall corrugated pipe useful life of up to 50 years. 8, excellent wear resistance in Germany have used the test to prove, HDPE even several times higher abrasion resistance than steel. 9, HDPE double wall corrugated pipe axial deflection certain length can flex slightly, uneven settlement without a certain degree of impact the ground, you can not directly laying pipe in the trench so slightly not straight.
