Growing Demand for Medium-Diameter PVC Pipe Production in Tunisia
With the continuous development of water supply infrastructure, agricultural irrigation systems, and underground drainage networks in Tunisia, the demand for stable and continuous PVC pipe manufacturing has increased significantly.
A local pipe manufacturer recently introduced a 90–315mm PVC Pipe Extrusion Line to improve production efficiency, maintain dimensional consistency, and support long-cycle industrial pipe manufacturing.
The extrusion system is designed for medium-diameter PVC pipe applications, including:
Municipal water supply systems
Agricultural irrigation pipelines
Underground drainage networks
Industrial fluid transportation systems
Why Is Stable PVC Pipe Production Important?
In 90–315mm PVC pipe production, manufacturers often face several technical challenges during continuous operation:
Diameter fluctuation during extrusion
Wall thickness inconsistency
Cooling shrinkage deformation
Instability in vacuum calibration
Synchronization issues between extrusion and haul-off systems
These factors can directly affect pipe connection performance, downstream installation efficiency, and long-term pipeline reliability.
To address these production requirements, the customer required a stable extrusion solution capable of maintaining continuous operation and dimensional accuracy.
Technical Configuration of the 90–315mm PVC Pipe Extrusion Line
Conical Twin Screw Extruder
The extrusion system uses a conical twin screw extruder specifically configured for PVC material processing.
The screw structure provides:
Stable plasticization performance
Uniform material flow
Consistent melt pressure during continuous extrusion
This helps improve dimensional consistency during medium-diameter pipe production.
Optimized Pipe Die Head System
The die head system is designed for balanced melt distribution across the pipe circumference.
The optimized flow channel structure helps maintain:
Stable outer diameter
Uniform wall thickness
Smooth pipe surface quality
during continuous production cycles.
Vacuum Calibration System
The vacuum calibration section provides stable outer diameter shaping during the initial cooling stage.
The system helps reduce:
Ovality deviation
Diameter fluctuation
Pipe deformation caused by unstable vacuum pressure
This improves dimensional accuracy for 90–315mm PVC pipes.
Multi-Stage Cooling System
The cooling system is configured to improve heat dissipation efficiency during continuous operation.
By controlling the cooling process, the line reduces:
Thermal shrinkage variation
Pipe bending deformation
Cooling instability during long production cycles
PLC Automatic Synchronization System
The PLC control system coordinates:
Extrusion speed
Haul-off speed
Cutting synchronization
This improves continuous production stability and reduces manual adjustment requirements during operation.
