This extrusion line consists of high efficiency single screw extruder die head, vacuum calibrating tank, water spraying cooling tank, haul-off machine, cutting machine, stacker etc.
1、Single screw extruder adopts long L/D, high efficiency screw, high extrusion capacity, uniformed plasticization. Extruder and haul off machine motors adopt imported AC/DC inverter as speed regulators.
2、Extrusion die head is spiral type, good calibrating makes good quality pipe production.
Inner heating system, high efficient, easy extrusion. Bronze calibrators can make the pipes fast calibrated and cooled.
3、Vacuum calibrating tank and water spraying cooling tank adopts advanced water circulation, high pressure cooling system, installed with vacuum degree adjusting device and automatic water temperature and water level controlling system.
4、Haul off machine adopts caterpillar type, which includes two-claw types, three-claw types, four-claw types, six-claw types, eight -claw types, ten-claw types, twelve-claw types etc, suitable for different sizes of pipes.
5Non-scraped cutting, saw cutting or planetary cutting can be applied, accurate cutting, reliable property, high efficiency. Meter-counting device is also installed.
Pipe produced by this line has excellent hardness and flexibility, heat resistance, aging resistance, high mechanical strength, environmental stress cracking resistance and creep resistance, hot-melt connectivity, and other advantages, it is the first choice of city gas and water transmission pipe line.
