HDPE Jacket Pipe Extrusion Line with Technical Service Free Training Vacuum Water Spraying Cooling and High Strength for Pre-Insulated Pipe Production

The vacuum calibration polyurethane insulation pipe is a kind of high efficiency pre insulated pipe. It is mainly composed of working steel pipe, PU insulation layer, plastic outer protective pipe and other parts.

The working steel pipe is in the innermost layer and assumes the conveying medium(For example: hot water, steam) function. In the middle there is a PU insulation layer, playing the role of heat preservation and insulation, which can effectively reduce heat loss. The outermost layer is a plastic outer protective tube, usually made of materials such as high-density PE. It can protect the insulation layer from the external environment erosion, but also make the pipe appearance more regular.

Main Extruder

Structural features: high strength, wear resistance, corrosion resistance, good screw plasticization effect; The temperature control system adopts ceramic heating coils for heating and fan cooling, and uses temperature sensors, temperature controllers, etc. for automatic temperature control.

Control system

Adopting Siemens PLC centralized control and unique DCL software design. Implemented interoperability between systems, windows, and human-machine interfaces, endowing machines with AI intelligence and simple operation. Save labor and effort, with no safety hazards

Planetary cutting machine

By using the Haff block planetary cutting machine, it can ensure that the cutting section is vertical and neat, without the need for secondary processing. Adding a powder collection system can ensure a clean and tidy production site.
