Based on 20 years of plastic extrusion machinery development and design experience, SHUANGLIN combined the advanced technology to prompt this Large Caliber HDPE Pipe Extrusion Line. Its unique structure design and high efficiency performance makes it fast accepted by the pipe factories. The Large Caliber HDPE Pipe Extrusion Line consists of high efficiency single screw extruder, vacuum calibration, spraying water cooling tank, multi-claw haul-off machine, pipe stacker and trolley. HDPE pipe widely applied on gas and water transportation. The extrusion line can be used to produce two layer or three layer HDPE pipes also, which takes the recycled material on the outer layer or middle layer to decrease the cost. It adopts PLC control system and HMI for whole extrusion line, synchronization function realized, as well as the winding machine. It helps the group machine production management and quality control. to be confirmed
