I. Pipe Usage
---HDPE jacket pipe is out case of thermal insulating pipe, which is widely used in central heating, oil, nature gas and other industrial area.
II. Machine Advantages
---High-efficiency extruder gives larger output, stable performance.
For example SJ75/33---250-350kg/h
SJ120/33---700-900kg/h
SJ150/33---800-1200kg/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.
III. 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.
IV. 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.
V. Electrical system ---ABB frequency converter or EUROTHERM speed controller ---Japan RKC temperature controller
--- SIEMENS AC contactors
