HDPE Water/Gas Supply Pressure Pipeline Single & Multi-Layer Co-Extrusion Line

Description

HDPE pressure Pipe Extrusion Line is a pipe extrusion line developed by HSD company through assimilateing the master technology introduced from Europe. It is applicable for extrusion of PE, PP, PB, PERT, ABS etc.

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.

1. Single Screw Extruder
Single screw extruder is composed of AC motor, hard toothed surface ,reduction gearbox, extruding system, heating and cooling system, and electrical controlling part. AC motor connects reduction gearbox directly and make screw rotate at certain speed to adapt to extrude certain 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 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 bronze 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 achieve 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 achieve cutting at certain length.
6. No-Dust Cutter
It adopts blade punching principle to achieve no-dust cutting. It is mainly composed of cutting device, clamping device, structure synchronous mobile device, and frame.

Working Conditions
