Introduction of HDPE Large Diameter Hollow Wall Winding Pipe:
HDPE Large Diameter Hollow Wall Winding Pipe produced by this line has high ring stiffness, high brunt intensity and low weight due to its unique structure. In addition, it has many advantages such as good creep deformation resistance, outer pressure resistance, erosion resistance (such as acid, alkali and salt etc.), long life of approximate 50 years, 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 have wide foreground and market potential.
Features of HDPE Large Diameter Hollow Wall Winding Pipe Extrusion Line:
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.
1st single screw extruder for square shaped pipe and 2nd single screw extruder for melting glue material: Extrusion of low energy consumption and low temperature plastication compliant with material characteristic (heavier molecular weight); unique screw design of distance-changing and separation of solid material and melting material; unique design of loading system ensures large increasing of extrusion capacity; special design of high mix-melting ensures the success of low temperature plastication.
Spiral forming unit: Adopts advanced multi-axes transmission box with feature of high transmission force and stable running performance; adopts unique design of composite die-head, after rotational molding the combined feed, extrude PE winding pipe together with two sets of extruder; winding pipe is of high quality by adopting the unique winding process of pipe forming. The glue extruder can be moved up and down, left and right. PLC computer control system with touch screen interface can realize automatic and reliable operation.
Cutting part: Saw cutting with desired length. Omron or Mitsubishi PLC computer control system with touch screen interface can realize automatic and reliable operation.
PLC computer control system with touch screen: With super high speed and large storage capacity
Multi control points: Forming pipe extrusion, melting PE adhesive extrusion, winding and cutting process can be auto-tail controlled synchronously; separately controlling two extruders and winding unit in tandem with two touch screens.
