Plastic steel spiral pipe is a non-pressure pipe suitable for gravity self-flowing conveying of media. The special structure of the pipe gives it good ring stiffness, so it has a higher ability to withstand external pressure.

After the introduction of plastic-steel spiral pipes into my country in 2005, the quality of pipes has been greatly improved through the unremitting efforts of manufacturers, equipment manufacturers, national chemical building materials testing departments, water supply and drainage design and research departments, and plastic industry experts. In addition, many easy-to-construct, safe and reliable connecting pipes have been invented, which can fully meet the drainage needs of various industries. As long as the civil construction unit cooperates closely, it is easy to achieve zero leakage of the conveying medium. Traditional drainage pipes cannot do this.
