Plastic steel winding pipe is a kind of non-pressure pipe, which is suitable for gravity self-flow transportation of medium. The special structure of the pipe makes it have good ring stiffness, so the ability to withstand external pressure is high.
Plastic steel winding pipe was introduced into our country in 2005, after the majority of manufacturers, equipment manufacturers, the national chemical building materials testing department, water supply and drainage design and research departments and the unremitting efforts of the plastics industry experts, so that the quality of the pipe has greatly improved, and invented a lot of easy to construct safe and reliable connection fittings, can fully meet the needs of various industries drainage. As long as the close cooperation with the civil construction unit, it is easy to achieve zero leakage of the transport medium. The traditional drainage pipe is unable to do.
