The HDPE large diameter hollow wall winding pipe produced by this line features high ring stiffness, high impact strength, and low weight, thanks to its unique structural design. In addition, it offers excellent resistance to creep deformation, external pressure, and chemical erosion (including acids, alkalis, and salts), with a long service life of approximately 50 years. This pipe has been widely used for municipal sewerage and drainage systems and is set to replace traditional cement pipes, cast iron pipes, and other conventional piping materials. Its low assembly cost, ease of operation, simple connection, and economical installation provide broad market prospects and significant potential.

HDPE Large Diameter Hollow Wall Winding Pipe Production Line designed with advanced technology includes 1st single screw extruder for square shaped pipe, square shaped pipe extrusion die, vacuum calibration water tank, spray cooling water tank, 2ND single screw extruder for melting glue material, spiral forming unit, cutting unit and stack unit.
