HDPE) 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: 1, strong ability to resist external pressure outer wall in 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. 2, low engineering cost under the condition of load, such as, HDPE double-wall corrugated pipe only need thinner wall can meet the requirements. As a result, with 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. 3, construction is convenient, because the HDPE double-wall corrugated pipe light weight, handling, and connection is very convenient, so the construction of efficient, simple maintenance. In the tight and poor conditions of construction condition, its advantage is more obvious. 4, small friction coefficient, large flow using HDPE as material of HDPE double-wall corrugated pipe of the same size than other pipe can be more traffic. In other words, under the same flow requirements, can use HDPE double-wall corrugated pipe diameter is relatively small. 5 the impact resistance, low temperature resistant HDPE double-wall corrugated pipe is the embrittlement temperature - 70℃。 The condition of low temperature ( - More than 30 ℃) Don't have to take special protective measures during the construction, the winter construction is convenient, and HDPE double-wall corrugated pipe has a good impact resistance. 6, good chemical stability because of 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, not

bacterium, not scale, its circulation area will not reduce with the increase of running time. 7, long service life 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. 8, excellent wear resistance Germany used test showed that the wear resistance of HDPE or even several times higher than steel pipe. 9, appropriate deflection lengths 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.
