Function Description

1

Raw Material Hopper & Auto Loader

Stainless steel hopper, vacuum auto-loading

1 set

Stores PE resin and automatically conveys raw material into the extruder feed throat; reduces manual labor and ensures continuous feeding.

2

Single Screw Extruder

SJ-150 / 33

1 set

Core extrusion unit; plasticizes and melts PE resin with stable output, designed for large-diameter jacket pipe production.

3

Extrusion Die Head (Mold)

Spiral mandrel die, Φ1155–2000mm range

1 set

Forms molten PE into a continuous tubular shape; ensures uniform wall thickness and concentricity of the jacket pipe.

4

Vacuum Calibration Tank

Stainless steel, vacuum + water cooling

1 set

Fixes pipe diameter and roundness under vacuum; cools and sizes the extruded pipe with precise dimensional control.

5

Haul-off Machine (Tractor)

multi-track, variable speed

1 set

Pulls the pipe forward at a constant speed synchronized with extrusion; maintains stable production line speed.

6

Planetary Chipless Cutter

Planetary rotary cutting, dust-free

1 set

Cuts PE jacket pipe to required lengths automatically; produces clean, burr-free cut ends without material waste.

7

Pipe Discharge Rack

1 set

Receives and stacks finished pipes

8

Electrical Control Cabinet

PLC + touch screen HMI, inverter drive

1 set

Central control system; monitors and regulates temperature, speed, vacuum and cutting parameters for fully automatic operation.

Note: Specifications are configurable based on pipe diameter range (Φ110–2000mm) and customer production requirements.
