Product Description

HDPE Pipe Extrusion Line for burried pre-insulation pipe

The line is an integration design composed by extrusion, vacuum calibrating, cooling, pulling, cutting, stacker. Great performance in automatic operation, extrusion capacity, steady and service life etc. Especially compared with the line use internal pressure method, vacuum calibrating method is much better than it for stiffness, pressure resistance and surface smooth.

Vacuum calibrating method pre-insulated pipe outside casing extrusion line is the most advanced and popular machinery in the world.




HDPE Pipe Extrusion Line for burried pre-insulation pipe 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.

HDPE Pipe Extrusion Line for burried pre-insulation pipe 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.
