HDPE Large Diameter Hollow-wall Winding Pipe produced by this line has high ring stiffness (4KN, 8KN), high brunt intensity and low weight due to its unique structure. PLC computer control system with touch screen interface can realize automatic and reliable operation. The rectangles pipes are extruded by the first extruder and then enter into twine from machine, at the same time, the second extruder spray the rubber strips and then squeeze to reunite it. Its outside wall is seat and smooth. In addition, it has many advantages such as good creep deformation resistance, outer pressure resistance, corrosion resistance (such as acid, alkali and salt etc.), long life of approximate 50 years, and no pollution and so on. It has been widely used for sewerage and drainage in city; it will replace the cement pipe, cast iron pipe and other pipes. Its low cost of assembling, easy operation, easy connection and economical construction can make it wide foreground and market potential.
