توضیحات محصول

Polymer concrete drainage pipe is a new type of pipe material for renovating old urban sewage networks. It uses corrosion-resistant, high-strength polymer concrete as the material and is equipped with embedded stainless steel sleeves. It resists external pressure and has a service life of up to 100 years, making it a replacement for traditional reinforced concrete pipes and plastic pipes. It is manufactured by centrifugal casting and large-scale mass production on automatic production lines, with integrated molds, centrifugal casting process, and one-time forming, offering high dimensional accuracy and good overall performance. The jacking pipe is used in open-cut and trenchless jacking construction scenarios, with many years of successful experience domestically and internationally, and is widely applicable to municipal, transportation, water conservancy construction projects, and other fields. Typical application: pumping discharge, inverted siphon, and other pipelines subjected to internal water pressure.
