Pipe diameter range: 110-2200mm

The vacuum-calibrated polyurethane-insulated pipe is a high-performance pre-insulated piping system. It primarily consists of a core steel pipe, a polyurethane (PU) foam insulation layer, and a protective plastic outer casing, among other components.

Key Features:
Production Method: Utilizes a vacuum calibrating technique.
Quality: Ensures smooth internal and external walls.
Durability: Offers a long service life with excellent anti-corrosion properties.
Performance: Delivers outstanding mechanical characteristics.

It is suitable for a wide range of thermal and cryogenic insulation applications, including hot/cold water supply, petroleum pipelines, and high/low-temperature pipeline systems.

Performance and advantages

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 the die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diame

Vacuum Calibration Tank
The vacuum calibration tank is mainly composed of a 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 calibrate the 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
The haul-off machine is mainly composed of a driving device, track, clamping structure, adjusting system, side plate and foundation bed. Haul-off caterpillars are driven by AC motor with frequency conversion control to adapt to different extrusion speeds.
An automatic length measuring device realizes cutting at a set length.

Chipless cutting
It adopts the blade punching principle to realize no-dust cutting. It is mainly composed of a cutting device, clamping device, structure synchronous movement device and frame.

Control system
ABB frequency converter or EUROTHERM speed controller
Japan RKC temperature controller
SIEMENS AC contactors
A controlling system can be designed according to customers' requirements.
