A: A PP pipe extrusion line typically includes an extruder, die head, cooling system, haul-off unit, and cutting device. These components work together to melt, shape, cool, and cut polypropylene pipes. Advanced systems may also feature automated controls for precision.
A: HDPE pipe extrusion requires lower processing temperatures (160-220°C) compared to PVC (170-210°C), with HDPE needing slower cooling to prevent crystallization. Material handling also differs, as HDPE is non-toxic during melting while PVC releases fumes requiring ventilation.
A: Production speed depends on pipe diameter, wall thickness, material melt index, and cooling efficiency. Larger diameter pipes generally require slower speeds for proper cooling. Advanced temperature control systems can optimize throughput while maintaining quality.
A: Degassing removes volatile compounds and moisture from molten PVC to prevent bubbles and defects. This critical process ensures structural integrity and smooth surface finish. Proper venting design in the extruder barrel enables effective volatile removal.
A: While technically possible with component changes, dedicated lines are recommended due to different temperature requirements and material contamination risks. Switching materials typically requires screw/barrel replacements and thorough cleaning to prevent cross-contamination.
