Three-layer Composite PP Pipe Extrusion Line

2022-07-04

Pipe has three layers to provide the highest mechanical performance:

1. External black PP layer provides excellent impact resistance and long-term UV protection;

2. Intermediate PP-MD layer provides high mechanical resistance and excellent sound proofing performance;

3. Internal layer low-friction, white PP layer provides the best flow performance, high resistance to chemical agents and high-definition contrast for visual monitoring.

 

Ningbo Fangli Technology Co., Ltd. is a mechanical equipment manufacturer with nearly 30 years’ experiences of plastic pipe extrusion equipment, new environmental protection and new materials equipment. Here we’d like to introduce our G series 160 three-layer composite PP pipe extrusion Line to you for reference:

G series 160 three-layer composite PP pipe extrusion line is the new enhanced product. It is suitable for producing PE, PPR, PPC, PP plastic pipe and so on. It is high automatic, stable and reliable, high effective and so on.

 

The process of three-layer composite pipe production line:

First, the SFPE materials, which was pre-dried, has loaded into the hopper; regarding screw turning the PE materials is feeding inside the single screw extruder.

Second, the materials become melting after going through the heating barrel and screw friction; therefore the material is very easy to flow and mold.

Third, the melting material goes through the heating die adapter, calibration sleeve, vacuum calibration tank and spray tank, then becomes expectant product.   

Fourth, the pipe is hauled by the caterpillar traction unit and is sent into the cutter where the pipe is cut off according to the pre-set length; at the same time, the cutting dust is removed by the dust-remover.

Fifth, the fixed-length pipe is sent to the storage table, which has the auto-unloading function.

 

The components of the 160G three-layer composite PP pipe extrusion line as follows:

1. FLSJ-G series High-efficiency Single Screw Extruder, FLSJ60-36AG: middle layer extrusion;

2. FLSJ-G series High-efficiency Single Screw Extruder, FLSJ45-36AG, 2 units: one for external layer extrusion, one for internal layer extrusion;

3. Multi-layer Extruder Die with marking line pipe;

4. Single Screw Co-extruder for Marking Strips;

5. Calibration Sleeve;

6. Vacuum Calibration Tank;

7. Spray Cooling Tank;

8. Haul-off: caterpillar traction;

9. Electric Chipless Cutting Machine;

10.  Two-station Pipe Coiler
