The Large Diameter HDPE Pipe Extrusion Line,customize and automated
Product desciption:
HDPE pressure Pipe Extrusion Line is a pipe extrusion line
developed by HSD company through assimilate and master technology
introduced from abroad. It is applicable for extrusion of PE, PP,
PB, PERT, ABS etc. This PE pipe production line can instead
extrusion line imported from abroad.

This pipe extrusion line mainly includes single screw extruder,
molds, vacuum calibrating water tank, spray water cooling tank,
haul-off machine, cutting machine and bracket.
Plastic Pipes produced by this line have excellent stiffness,
flexibility, high mechanical strength, resistance of environmental
stress cracks, resistance to creep deformation, heat-linkage and so
on. It has become the first choice for the city gas pipe, water
supply pipe, foundation pipe, landfill collection pipe, watermain,
geothermal heating etc.
Application:
HDPE pipe extruding line composed of single screw extruder and
corresponding auxiliaries, can produce all kinds of small diameter
HDPE plastic pipes continuously. It also can be used to produce PS,
PP, HDPE plastic pipes after replacing the screw. HDPE plastic pipe
is widely used for liquid conveying in agricultural, chemical
industry, construction industry, etc.
Structure
HDPE pipe extruding line is mainly composed of single screw
extruder, die-head, vacuum forming tank, spray cooling tank,
haul-off device, cutting device, and pneumatic discharging frame.
1. Single Screw Extruder
Single screw extruder is composed of AC motor, hard toothed surface
reduction gear, extruding system, heating and cooling system, and
electrical controlling part. AC motor transfer the power to
reduction gearbox via V-belt wheel and make screw rotate at certain
speed to adapt to extruding all kinds of plastics.
2. Die-Head
Die-head is mainly composed of mandril, neck mold, spiral body,
cover, die-head body, bolts, and heating rings. The inside surface
touching with plastic materials is polished and chrome plated to
ensure plastic materials flow smoothly and to ensure no rusting.
The uniformity of pipe wall thickness can be adjusted by bolts. The
copper calibrating sleeve fixed in die-head is mainly used to cool
down the fresh pipe and to calibrate the pipe outer diameter.
3. Vacuum Forming Tank
Vacuum forming tank is mainly composed of frame, stainless steel
tank, vacuum system, spray cooling system, back and forth mobile
device. When it is at work, the vacuum pump exhausts the air from
the sealed tank to pressurize the fresh pipe cling to calibrating
copper sleeve and to realize calibrating the pipe outer diameter.
Spray cooling system is used to cool down the extruded pipe by
water. Spray nozzles spray cooling water from all directions on
pipe surface to cool down the pipe promptly.
4. Water Cooling Tank
Water cooling tank is mainly composed of frame, stainless steel
tank, and spray cooling system. Spray cooling system is used to
cool down the pipe further and to realize cooling completely and
forming.
5. Caterpillar Haul-off Machine
Haul-off machine is mainly composed of driving device, haul-off
chain caterpillar, clamping structure, adjusting system, side
plate, and foundation bed. Haul-off caterpillars are AC motor
driven and adopt frequency control of speed to adapt to different
pipes extruding speed. It is also equipped with automatic length
measuring device to realize cutter cutting at set length.
6. No-Dust Cutter
It adopts blade punching principle to realize no-dust cutting. It
is mainly composed of cutting device, clamping device, structure
synchronous mobile device, and frame.
7. Discharging Frame
The table surface is made of stainless steel. It adopts pneumatic
overturn and discharging automatically.
