Comrise 's Hollow Wall Winding Pipe Machine specializes in producing spirally wound HDPE/PP pipe with a structural rib design, creating lightweight, high-strength pipe suitable for gravity flow applications. It integrates automated winding, welding, and calibration functions to produce pipe with high-quality, leak-proof joints.
Core Components
Turbine Winding Unit: Dual servo motors achieve a speed of 10-20 rpm and adaptive tension control for uniform rib formation.
Co-Extruder: The Hollow Wall Winding Pipe Machine utilizes a twin-screw design and processes HDPE/PP at temperatures of 180-230°C, enabling simultaneous extrusion of the inner liner.
Welding System: A hot air welding gun ensures seamless interlayer bonding with a peel strength of ≥30 N/cm.
Calibration System: Three-stage vacuum cooling and zoned temperature control achieve an accuracy of ±3°C to prevent pipe warping.
Production Process
The material is melted and formed into a continuous strip in the extruder. The strip is spirally wound around a mandrel and welded layer by layer.
Ribs are formed by synchronized die rotation and provide structural reinforcement.
The pipe is gradually cooled in a vacuum tank to ensure dimensional stability.
The Hollow Wall Winding Pipe Machine automatically cuts to length and trims the ends.
