Strong compressive ability: The internal structure of the HDPE drainage pipe is relatively smooth, which greatly enhances the ring stiffness of the pipe, thereby enhancing the resistance of the pipe to soil load; the coefficient of friction is small and the passing ability is strong: the coefficient of friction of the inner wall of the HDPE drainage pipe is 0.009, while the friction coefficient of the inner wall of the reinforced concrete pipe is 0.013. Therefore, the HDPE drainage pipe can pass a larger flow rate than other pipes of the same diameter; construction is convenient: due to the light weight of the HDPE pipe, it is very convenient to carry and connect, so Construction is fast. In the case of tight construction period and poor construction conditions, its advantages are more obvious; good chemical stability and long service life: HDPE molecules have no polarity, so chemical stability is good, and factors such as soil, electricity, acid and alkali in the general use environment are not will damage the pipe. In the case of burial, the service life of HDPE pipe can reach more than long-term durability according to standards; proper deflection: HDPE drainage pipe is a flexible pipe material, which can resist a certain degree of uneven settlement of the foundation, and the pipe interface is tight and no leakage; green environmental protection: Conform to the requirements of the times, green and environmental protection. The pipe meets the national environmental protection requirements, is non-polluting, non-toxic, and can be recycled.
