The large-diameter HDPE hollow-wall spiral winding pipe production line, developed using advanced domestic and international technologies, can produce drainage pipes with diameters ranging from 300mm to 3500mm. The pipes produced by this line feature high ring stiffness, strong creep resistance, convenient connection, permanent leak-proof performance, and high cost-effectiveness. These pipes are gradually becoming the mainstream product for urban drainage systems, progressively replacing steel pipes, cement pipes, and pipes made of other materials.

This production line adopts an advanced Siemens PLC computer control system, offering high production efficiency, stable operation, and simple, convenient operation.
