Ppu Pre-Insulated Pipe Plastic HDPE Jacket Casing Pipe Extrusion Line Plastic Extrusion Machine

Description
HDPE Jacket Pipe Extrusion Line is high-efficient with high speed and energy saving for producing HDPE thin wall pipe, which is used as a protective cover of PU foam thermal Pre-insulated Pipe according to international standard.
The HDPE jacket pipe is produced by vacuum calibrating method with smooth internal and external wall, long service life, good anti-corrosion insulation and mechanical performance.

Working Conditions

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.

---Pipe Usage: out case of thermal insulating pipe, which is widely used in central heating, oil, nature gas and other industrial area.
---Pipe/jacket diameter range: 110-1680mm

Machine Advantages
---High-efficiency extruder gives larger output, stable performance.
---Pipe wall is average and smooth, to reduce waste of raw material, and pipe thickness is adjustable.
---No need trim edge, once forming.
---High degree of automation, can be operated by one person, saving labor costs.

Main machine- High-effeciency single screw extruder
---Single screw is with barreir & mixing head; Barrel is new model with slotting (channel), Both make security of good jellification, large output and stable performance.

Controlling system
The complete line could be controlled by PLC, with good human-machine interface, all technical parameters could be set and indicated by touching screen. Controlling system is designed according to the customer; S requirement, to be with PLC, or without.
