PPR / PP Cold and Hot Water Pipe Plastic Extrusion Production Line
I. Product Description
PPR (Random Copolymer Polypropylene) / PP (Polypropylene) cold and hot water pipes are plastic pipes used in building water supply, heating, underfloor heating, and other fields. They feature high temperature resistance (long-term use temperature ≤ 95°C), pressure resistance, corrosion resistance, hygiene and non-toxicity, long service life (50 years+), and easy installation, making them an ideal replacement for traditional metal pipes. This production line is specifically designed for producing PPR/PP cold and hot water pipes in different specifications such as DN16~DN110, meeting national standards and engineering requirements.
II. Equipment Advantages (Core Selling Points)
Optimized design specifically for PPR/PP materials, ensuring stable melt, smooth inner and outer pipe walls, and precise dimensions
Supports high-speed extrusion, high production efficiency, suitable for large-scale production
Modular design, supports customization for different pipe diameters (DN16-DN110) and wall thicknesses
Equipped with complete downstream processes: vacuum sizing, spray/air cooling, traction, cutting, etc.
Automated control: closed-loop control of temperature, speed, and pressure ensures stable quality
Provides turnkey services: Extrusion line equipment (Single/Twin Screw) • PPR/PP specific formulations (Raw material + Additives) • Process technical guidance (Formulation, temperature, speed, etc.) • After-sales support and operation training • Supports OEM production / Custom branding • Permanent online video technical support

VI. Process Flow Chart (Text Version)
Raw Material Preparation: PPR/PP pellets dried
Mixing (Optional): Add color masterbatch, additives, mix uniformly
Extrusion: Melted and plasticized through extruder, extruded into tubular shape via die
Vacuum Sizing: Pipe passes through vacuum tank, outer diameter stabilized and preliminarily cooled
Cooling: Water cooling or spray cooling to fully solidify the pipe
Haul-off: Evenly pulls the pipe, maintaining consistent speed
Cutting: Automatically cuts to set length
Collection: Finished pipes stacked or packaged
VII. Application Fields
