Glass fiber tape winding reinforced composite pipe production equipment
This production line is designed for continuous manufacturing of Glass Fiber Tape Winding Reinforced Thermoplastic Composite Pipe (RTP/TCP). The system adopts pre-impregnated unidirectional (UD) tape winding / in-situ consolidation process, using hot air heating to achieve simultaneous winding and fusion without post-curing. The produced pipe features a three-layer structure: inner liner (PE/PP/PERT/PA), reinforcement core (interlaced glass fiber UD tape winding), and outer protective layer (abrasion-resistant/UV-stable/flame-retardant). Pipe diameter ranges from 50 to 600mm, with maximum pressure rating up to 30MPa, offering a reliable alternative to traditional metal and GRE pipes.
Working Principle & Process Flow
Inner liner extrusion: Single/twin screw extruder extrudes thermoplastic (PE/PP, etc.) to form a continuous inner pipe through a die.
Glass fiber tape winding reinforcement: The inner pipe enters a 4-spindle (or multi-spindle) winding unit. Glass fiber UD tape is wound at set winding angles (±45°~±60° adjustable) under constant tension, with multiple interlaced layers. Simultaneously, hot air nozzles heat the winding point for in-situ consolidation, fusing the tape with the inner pipe to form the reinforcement core.
Outer coating: The reinforced pipe enters a second extruder to apply an outer protective layer (color stripes, flame retardant, etc. optional).
Cooling & sizing: Vacuum sizing tank + spray cooling.

Key Advantages
Versatile: Quick changeover between different reinforcement tapes (glass fiber/aramid/steel) for various pipe grades.
Continuous & efficient: Winding and consolidation occur simultaneously – no offline curing, greatly improving productivity.
Precise control: Automatic winding angle tracking, closed-loop tension control, PID temperature regulation ensure uniform defect-free reinforcement layer.
Eco-friendly & recyclable: Fully thermoplastic material; pipes can be recycled at end of life, meeting circular economy requirements.
Advantages over alternatives: Lighter, corrosion-resistant, flexible & spoolable compared to metal pipes; non-brittle and recyclable compared to GRE pipes.
