The PO Extruder for PPR/PERT/PB Pipes is a cutting-edge manufacturing system tailored for producing high-quality polyolefin pipes—including PPR (polypropylene random copolymer), PERT (polyethylene of raised temperature resistance), and PB (polybutylene)—for plumbing, heating, and industrial applications. This extruder combines speed, precision, and versatility to meet the growing demand for durable, energy-efficient piping solutions in residential, commercial, and industrial construction.

At its core is a high-shear mixing screw with a 38:1 L/D ratio, engineered to achieve homogeneous polymer blending and optimal melt quality. Paired with a precision metering pump (±0.5% dosing accuracy), this design ensures consistent material distribution, resulting in pipes with excellent thermal stability (PPR: 95°C continuous use, PERT: 80°C, PB: 110°C) and long-term creep resistance (≥10,000 hours at design temperature). The system’s multi-layer co-extrusion capability (up to 5 layers) allows integration of color stripes, oxygen barriers, or recycled materials without compromising performance. With rapid die changeover (≤15 minutes) and support for DN20-DN160 mm pipe diameters, it delivers production speeds up to 80 m/min while maintaining strict dimensional tolerances, making it a cost-effective solution for high-volume pipe manufacturing.
Material Compatibility: Processes PPR (MFR 0.3-1.5 g/10min), PERT (density 0.920-0.930 g/cm³), PB (MFR 0.5-2.0 g/10min), and PEX (cross-linked polyethylene). Supports recycled content up to 30% in non-critical layers, with material-specific processing parameters stored in the PLC.
Extrusion System: φ65-φ90 mm twin-screw extruder with self-cleaning, co-rotating screws that provide thorough mixing and degassing. Equipped with a grooved feed section for improved material intake, delivering 200-600 kg/h output.
Die Design: Spiral mandrel die with internal flow channels that ensure low-pressure extrusion (≤8 MPa), resulting in uniform wall thickness (±0.1 mm) and smooth inner/outer surfaces (Ra ≤0.8 μm).
Vacuum Calibration Tank: Stainless steel construction with adjustable vacuum pressure (0.02-0.08 MPa) and multi-zone cooling (3-5 zones) to ensure dimensional stability. Equipped with precision guide rollers and water level control.
Hauling Unit: Servo-driven caterpillar with 6-12 pairs of polyurethane rollers that provide 10-50 kN traction force with speed accuracy ±0.3%. Rollers are adjustable for different pipe diameters without tooling changes.
Cutting System: Flying saw with CNC-controlled positioning (±0.5 mm accuracy) and automatic length measurement. Includes dust extraction for clean operation.
PLC+HMI Interface: 15-inch touchscreen displaying real-time data on melt temperature (180-230°C, ±2°C), die pressure (5-15 MPa), and production speed (5-80 m/min). Stores 100+ recipes for quick changeover between pipe types and sizes.
Energy Efficiency: Features IE4 premium efficiency motors and variable frequency drives that reduce power consumption by 25% compared to standard extruders. Includes heat recovery from barrel cooling to preheat process water.

Renewable Energy
Constructs solar thermal pipes for solar water heating systems, with UV resistance (ISO 4892-3) and -40°C low-temperature flexibility (no cracking after 100 freeze-thaw cycles).
Produces geothermal heat pump pipes (PERT/PEX) that withstand ground temperatures up to 60°C and soil chemicals.
Q: What is the maximum continuous operating temperature for PPR pipes?
A: PPR pipes produced by this extruder are rated for 95°C continuous operation (with short-term peaks up to 110°C), PERT pipes for 80°C continuous use, and PB pipes for 110°C continuous operation—all verified through long-term thermal stability testing (ISO 9080).
Q: Can it integrate with existing pipe extrusion lines?
A: Yes, its modular design allows seamless integration with upstream granulation systems and downstream printing/coiling equipment. It supports standard industrial communication protocols (Profibus, Ethernet/IP) for synchronized operation with other line components.
Q: What maintenance is required for the extruder?
A: Recommended maintenance includes screw and barrel cleaning every 300 operating hours using purging compounds, bearing lubrication with high-temperature synthetic grease every 100 hours, and filter screen replacement every 800 hours to maintain melt quality.
Q: How does it ensure color consistency in colored pipes?
A: The system uses a precision color masterbatch dosing system with gravimetric feeders (±0.1% accuracy), integrated with the main extruder control to maintain consistent color concentration (1-5% by weight) across production runs.
