وصف المنتج

Polymer concrete drainage pipe is a new type of pipe for renovating sewage networks in old urban areas. 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 produced in large batches on automatic production lines, with an integral mold, centrifugal casting process, and one-piece forming, offering high dimensional accuracy and good overall performance. Typical applications: large-scale drainage networks, sewage interception mains (length customizable).
