HDPE gas water supply pipe production line is mainly used to extrude PE pressure pipes, pipe diameter ranging 20-2200mm.

The produced pipe has smooth surface and uniform wall thickness, the specification can meet the international standards of the product. The equipment can apply special extrusion molds and adopt multi-layer co-extrusion technology to reduce production costs.
Plastic Pipes produced by this line have excellent stiffness, flexibility, highmechanical strength, resistance of environmental stress cracks, resistanceto creep defommation, heat-inkage and so on.

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. Haul-off Machine
Haul-off machine is mainly composed of driving device, haul-off chain, clamping structure, adjusting system, side plate, and foundation bed. Haul-off tracks 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 Planetary 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.
