Vacuum Calibrating PU Pre-Insulated HDPE Casing Shell Jacket Pipe Extrusion Line

Product description:
Vacuum Calibrating Method Pre-Insulated Pipe extrusion line is designed by absorbing the tube extrusion developed technology from Germany and improved by Qingdao Huashida Machinery Co., Ltd.The line is an integration design composed by extruder, vacuum calibrating, cooling, pulling, cutting, stacker. Great performance in automatic operation, extrusion capacity, steady and service life etc. Especially compared with the line use internal pressure method, vacuum calibrating method is much better than it for stiffness, pressure resistance and surface smooth.

Vacuum calibrating method pre-insulated pipe outside casing extrusion line is the most advanced and popular machinery in the world.In the practice of domestic construction becomes increasingly used energy-saving technology trenchless laying of pipelines, using pipes and fittings with industrial thermal insulation of rigid polyurethane foam (PUF insulation) in protective shell.
Pipelines PUF insulation intended for installation of heating networks with a working pressure of 1.6 MPa and a water temperature to 403 ° K (130 ° C) with a valid short-term increase in temperature to 423 ° K (150 ° C).

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

Machine Advantages
---High-efficiency extruder gives larger output, stable performance.
For example
SJ90/33---600-700kg/h
SJ120/33---800-900kg/h
SJ150/33---1000-1200kg/h
---Compared with inflating method (internal pressure method)
1. For 24 hours working, it reduces 2-3 workers for each shift.
2. There is much waste pipe and material, no need workers to crush waste material.
3. High-effeciency. Take Dimater 960mm as an example, Output is approximately 60 pcs of 11.6meters pipe, it is much higher output than that of inflating method.
4. Pipe wall is average and smooth, to reduce waste of raw material, and pipe thickness is adjustable.
5. No need trim edge, once forming.

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.

Electrical system
---ABB frequency converter or EUROTHERM speed controller
---Japan RKC temperature controller
--- SIEMENS AC contactors
