The PPR pipe extrusion line is a specialized manufacturing system for producing polypropylene random copolymer (PPR) pipes, widely used in hot/cold water supply, heating systems, and industrial fluid transport. Known for high-temperature resistance (up to 95°C), corrosion immunity, and long-term durability, PPR pipes are ideal for modern plumbing infrastructure.
This fully automated line integrates precision extrusion, vacuum sizing, and advanced cooling to ensure smooth surfaces and consistent wall thickness. It supports production of pipes in diameters ranging from 20mm to 160mm, compliant with ISO 15874 and ASTM F2389 standards.
Designed for energy efficiency and low maintenance, the system emphasizes minimal thermal degradation and material waste. Its modular setup allows quick adjustments for color variations (e.g., green, white, or gray pipes) and recycled PP material integration.

Key Features

Twin-screw extruders with optimized screw design for uniform PP melting (220–260°C).
Multi-stage vacuum calibration for precise diameter control and internal/external smoothness.
Closed-loop cooling tanks with temperature control to prevent pipe warping.
Servo-driven haul-off units ensuring stable tension and wall thickness uniformity.
Laser marking systems for permanent printing of specifications (e.g., pressure rating, batch codes).
Automatic cutting and coiling (for small diameters) or stacking systems (for larger pipes).
Anti-oxidation air knives to cool the pipe surface post-extrusion.
Energy-saving heaters and insulation to reduce thermal loss.
