High Output HDPE Jacket Pipe Making Line with Vacuum Calibration and Single-Screw Extruder

Product Description

Product Description

HDPE Plastic Jacket Pipe Pre-Insulated Pipe Casing Extrusion Line

The HDPE jacket pipe extrusion line is a high-efficiency, high-speed, and energy-saving production system designed for manufacturing HDPE pipes used as protective outer casing for PU foam pre-insulated pipes, in compliance with international standards.

The HDPE jacket pipes are produced advanced vacuum calibration technology, ensuring smooth inner and outer surfaces, uniform wall thickness, and excellent product quality. The finished pipes feature long service life, superior corrosion resistance, outstanding insulation performance, and strong mechanical strength.

High-efficiency single screw extruder

Single screw is with barrier & mixing head; new model barrel with slotting (channel), Both make the security of good jellification, large output and stable performance.

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.

Vacuum Calibration Tank

Vacuum calibration tank is mainly composed of frame, stainless steel tank, vacuum system, spray cooling system, position adjustment device. The vacuum pump exhausts the air from the sealed tank to pressurize the fresh pipe cling to calibrating copper sleeve and to calibrate the outer diameter. Spray nozzles spray cooling water from all directions on pipe surface to cool down the pipe promptly.

Haul-off Machine

Haul-off machine is mainly composed of driving device, tracks, clamping structure, adjusting system, side plate and foundation bed. Haul-off tracks are driven by AC motor with frequency conversion control to adapt to different extrusion speed.
Automatic length measuring device realizes cutting at a set length.
