Product introduction:

Qingdao Benice Plastic Machinery Manufacturing Co,.Ltd. developed HDPE Large-diameter Burying Earth Hollow Wall Winding Pipe Production Line and FR-PP Winding Pipe Production Line by absorbing the freshest technique of home and abroad. It can produce high grade drainage pipe of diameter from Φ400 to Φ3000.
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 addtion, 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 wide foreground and market potential.The pipe more and more becomes the leading product of the town drains away water and shall substitute gradually steel tube, cement and else plastic material pipe.

Hollow all winding pipe production line: 
That production line contain profile tube extruder, melting connection extruder, winding forming machine, cutting machine, and related auxiliary device, having great production capacity, high efficiency, stable operating, high pipe circle rigidity, little unit meter weight, fine creep deformation resistant performance, convenience connection and economic installation. The tube has below types: Double wall ripple winding tube, dual wall winding tube, three-wall winding tube etc.
All Extruders adopt the special designed high efficiency single screw extruder, special structural screw and barrel, the yield is high, consume little energy, good plasticization, reasonable forming tool structure, two machines unites to provide material and revolving forming, choice conceiving and special design.
Advanced PLC computer control system can be chosen to ensure convenient, stable and dependable operation.
Adopting two steps type decompression screw, with specially promoting mixing and plasticization component, high twist torque and high temperature control accuracy.
Adopting composite die, two extruders unite to provide material, helix turning forming, high efficiency compound technology ensures high product quality.
