PLC Controlled Pre-Insulated Pipe Extrusion Line with Integrated
System for Stable Performance
Vacuum Calibrating HDPE Jacket Pipe Extrusion Line
High-Efficiency Solution for PPU Pre-insulated Pipe Outer
Protection
Product Overview
This extrusion line is high-efficiency equipment designed for
high-speed operation and energy saving. It is specifically used for
producing HDPE pipes that serve as the protective outer cover for Polyurethane (PU)
foam thermal pre-insulated pipes.
The machinery features a compact size, easy operation via an
automatic control system, and a long service life.
Pipe/Jacket Diameter Range: 110mm - 1680mm
Pipe Usage: Outer casing for thermal insulating pipes widely used in central
heating, oil, natural gas, and other industrial sectors.
Machine Advantages
High Productivity: The high-efficiency extruder ensures larger output and stable
performance.
Material Savings: Pipe walls are uniform and smooth, reducing raw material waste;
wall thickness is fully adjustable.
Seamless Production: No need for edge trimming; the pipe is finished in a single
forming process.
Labor Efficiency: High degree of automation allows the entire line to be operated by
a single person, significantly saving labor costs.

Detailed Technical Components
High-Efficiency Single Screw Extruder
The single screw is designed with a barrier and mixing head.
Features a new model barrel with feed slotting (channels). This
combination guarantees excellent jellification (homogenization),
large output, and stable performance.
Precision Die-Head System
The die-head is primarily composed of a mandril, neck mold, spiral
body, cover, die-head body, bolts, and heating rings. All internal
surfaces in contact with plastic materials are polished and
chrome-plated to ensure smooth flow and zero rusting. The
uniformity of the pipe wall thickness is precisely adjustable via
specialized bolts. A copper calibrating sleeve fixed in the
die-head is used to cool the fresh pipe and set the initial outer
diameter.
Vacuum Calibration Tank
Composed of a heavy-duty frame, stainless steel tank, vacuum
system, spray cooling system, and position adjustment device. The
vacuum pump exhausts air from the sealed tank to force the fresh
pipe against the copper sleeve, ensuring an exact outer diameter.
Spray nozzles deliver cooling water from all directions onto the
pipe surface to set the shape promptly.
Haul-off Machine
Composed of a driving device, tracks, clamping structure, adjusting
system, side plate, and foundation bed. The haul-off tracks are
driven by an AC motor with frequency conversion control to
synchronize with various extrusion speeds. Includes an automatic
length-measuring device to realize precise cutting at set lengths.
No-Dust Cutter
Adopts the blade punching principle to achieve high-speed cutting
without generating dust or waste. Composed of a cutting device,
clamping device, synchronous movement structure, and frame.
Centralized Control System
The complete production line is controlled by a PLC with a
high-quality human-machine interface (HMI). All technical
parameters can be set and monitored via a high-resolution touch
screen. The control system can be customized according to specific
customer operational requirements.
Discharging Frame
The table surface is constructed from corrosion-resistant stainless
steel. Utilizes a pneumatic overturn system for automatic
discharging of finished pipes.
