PU Foam Pre-Insulated Pipe Extrusion Line with HDPE Outer Jacket
The polyurethane (PU) pre-insulated pipe system, manufactured using an advanced vacuum calibration process, is engineered to deliver excellent thermal insulation performance and long-term operational reliability.
This system is composed of three main layers: an inner steel pipe, a polyurethane (PU) foam insulation layer, and a high-strength HDPE protective outer jacket. Pipe diameter range: 110-2200mm
Why Choose Our Production Line?
1.Vacuum Calibration Technology
Ensures precise dimensions and stable pipe quality.
2.Large Diameter Capability (Up to 2200 mm)
Perfect for district cooling and oil & gas projects.
3.High Insulation Performance
Uniform PU foam structure reduces heat loss.
4.Reliable in Harsh Environments
Stable operation under high temperature and desert conditions.
5.High Automation
Less labor, stable production, consistent quality.
6.Turnkey Solution
Complete line supply for fast project startup.
Application Areas
This system is widely used in various temperature-controlled pipeline applications, including:
District heating and cooling networks
Hot and chilled water distribution systems
Oil and gas transmission pipelines
Industrial processes requiring high or low temperature control

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
AC contactors
A controlling system can be designed according to customers' requirements.
