Huashida HDPE Jacket Pipe Extrusion Line For Pre-Insulated Pipe Plastic Machinery For Steel Pipe
HDPE Jacket pipe extrusion line for pre-insulated pipe is used for extruding thin wall shell to protect the Polyurethane foaming Prefabricated Directly Buried Insulating Pipe. China manufacturer Huashida company adopts vacuum calibration method. The line runs steady. It is easy to operate by Siemens PLC. High-speed and efficient production can save costs for customers. It is an environmental protection and energy-saving production line.
HDPE Jacket pipe: dia. 48-2000mm
Carrier pipes: steel/stainless steel/plastic/copper
Insulation layer: polyurethane rigid foam Material
---Pipe diameter range: 110-600mm 655-1372mm 960-1680mm
---The extrusion line comprise equipments and devices as below,
1set Vacuum loader
1set Hopper dryer
1set High-effeciency single screw extruder
1set single screw extruder for mark line
1set Vacuum calibration table
1set Water spraying tank
1set Hauling machine
1set Cutting machine
1set Stacker
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
SJ-75/33---250-350kg/h
SJ-120/33---700-900kg/h
SJ-150/33---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
