High cost performance ratio of double wall corrugated pipe:
The friction coefficient of double wall corrugated pipe is one of the reasons for the low flow rate of the pipe, and the pipes used for transportation and other pipes have great advantages. In other words, the double wall waveform of HDPE pipe with relatively small diameter at the same flow rate can be used. The brittleness temperature of low temperature resistant and impact resistant HDPE double wall wave tube is - 70 ° C. Under normal low temperature conditions (above - 30 ° C), no special protection measures are required.
If the double wall corrugated pipe is used in winter, the trust is very good for the construction team. Outstanding chemical stability, HDPE molecule has no accessibility, so its chemical function is excellent, except for some anti oxygen chemical agents, it will generally not have any damage.
The double wall bellows will not be damaged by the soil, electricity, acid and alkaline elements in the general environment. The outer surface of the pipe is fine - bacteria will not multiply or expand, and the circulating area will not be reduced with the addition of operation time. The double wall waveform of HDPE pipe can be used to insulate air for a long time, such as buried underground and exposed to sunlight for more than 50 years. Excellent construction! Generally speaking, the cost performance ratio is relatively high!
Double wall corrugated pipe It is a kind of pipe with strong resistance to external pressure. Its inner wall is smooth, and its outer wall is annular corrugated structure. This design enhances the ring stiffness of HDPE double wall corrugated pipe, and it also enhances the resistance of the pipe to soil load, which is an advantage that other pipes do not have. Double wall corrugated pipe is also a kind of pipe with low engineering cost. Compared with other pipes under the same load, the double wall corrugated pipe only requires thin wall, which can save about half of the raw materials, which also reduces the project cost.
The low temperature resistance and impact resistance of double wall corrugated pipe are also outstanding. Through test, verification and verification, it is proved that its brittleness temperature is - 70 ℃, and special protection measures can not be taken during construction under low temperature conditions of - 30 ℃. Winter construction is also relatively convenient. HDPE double wall corrugated pipe is very convenient for construction, because it is light in weight and convenient for transportation and connection. Compared with pipes of the same caliber, HDPE pipes have a larger flow rate. Therefore, in the case of flow requirements, the smaller diameter HDPE pipe can meet the requirements.
