PU Insulated Pipe Production Line
The name of product: PU Insulated Pipe Production Line
Description of the production: PU Insulated Pipe Production Line is a high efficiency equipment with high speed and energy saving which is developed by Qingdao Huashida Machinery Co.Ltd., PU Insulated Pipe is easy to operate with automatic control system and has long service life.
Description of WHAXT: Prefabricated directly buried insulating pipe cosist of steel pipe, polyurethane foam layer and PE jacket pipe. Because of its special structure, the PU Insulated Pipe is an irreplaceable role in municipal heating engineering.
The insulated pipe/jacket/jacket tube of PU Insulated Pipe/the thermal insulation pipe/jacket tube which is produced by vacuum calibrating method pre-insulated pipe outside casing extusion line of Qingdao Huashida Machinery Co. Ltd. is mainly made of HDPE after extrusion. This insulated pipe has smooth internal and external wall, long service life, its anti-corrosion insulation and mechanical performance is good, the installation of the insulated pipe is low. So the PU Insulated Pipe Production Line of Qingdao Huashida Machinery Co. Ltd. greatly reduced the cost of manufactory and improved the production.
The composition and characteristics of PU Insulated Pipe Production Line
1. High-effeciency single screw extruder
Single screw is with barreir & mixing head; barrel is new model with slotting (channel), Both make security of good jellification, large output and stable performance.
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. 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.
Main Extruder: SJ-75/33
Pipe Diameter: Φ110-600mm
Installed Power: 160kw
