PE steel wire mesh skeleton mining pipe Ultra wear-resistant composite pipe It not only has the common advantages of plastic pipes, such as anti-corrosion, non scaling, smooth and low resistance, heat preservation, non waxing, and wear resistance, but also has the following characteristics due to its unique structure:
(1) Good creep resistance and high durable mechanical strength.
(2) Good temperature resistance.
(3) It has good rigidity, impact resistance, dimensional stability and moderate flexibility.
(4) The linear expansion coefficient is small. Linear expansion coefficient of pure plastic pipe is 170 × 10-6 (1/℃), the linear expansion coefficient of composite pipe super wear-resistant composite pipe is 35.4~35.9 × 10-6 (1/℃), lower than any common plastic pipe;
(5) Rapid cracking will not occur.
(6) Good self tracing. Due to the existence of the steel mesh skeleton, the steel mesh skeleton polyethylene composite pipe buried underground can be located by the usual magnetic detection method to avoid damage caused by other excavation projects;
(7) The product structure and performance can be adjusted conveniently and flexibly.
(8) The special electric fusion joint has various varieties, and the installation is very fast and reliable. The PE steel wire mesh skeleton mining pipe is connected by electric melting connection and flange connection. The electric melting connection is to insert the composite pipe into the electric melting pipe fitting, and energize the electric heating wire embedded on the inner surface of the pipe fitting to heat it. First, melt the inner surface of the super wear-resistant composite pipe fittings to produce melt, and the melt expands and fills the gap between the pipe fittings until the outer surface of the pipe also produces melt. The two melts are fused together. After cooling and molding, the pipe and the pipe fittings are closely connected as one.
