The High-Capacity HDPE Pipe Extruder for Water/Gas Pipes is a heavy-duty manufacturing solution engineered to meet the stringent demands of large-scale water distribution and gas transmission networks. As global infrastructure upgrades accelerate, this system delivers the production capacity, material efficiency, and product quality required for critical pipeline projects. Its robust design centers on a high-torque gearbox (25,000 N·m) and deep-flighted screw with a 30:1 L/D ratio, ensuring uniform melt homogeneity even for high-viscosity HDPE 100 materials.

This extruder produces pipes with excellent pressure resistance (PN10-PN25) and long-term hydrostatic strength (≥20 MPa at 20°C for 10,000 hours), meeting the most rigorous standards for water and gas applications. The multi-layer co-extrusion capability (up to 5 layers) enables cost optimization by integrating recycled materials in inner layers while maintaining critical properties in outer layers. With production outputs reaching 800-2,000 kg/h and support for DN200-DN2000 mm pipe diameters, this system reduces per-unit production costs by 15% compared to conventional extruders, making it ideal for large infrastructure projects, municipal water mains, and high-pressure gas transmission lines.
Material Compatibility: Optimized for HDPE 100 (PE100) and PE80 resins with density 0.941-0.965 g/cm³, also compatible with PEX for cross-linked polyethylene pipes. Supports recycled content up to 50% in multi-layer structures, verified through mechanical testing.
Extrusion System: φ120-φ200 mm twin-screw extruder with self-cleaning, intermeshing screws that ensure thorough mixing and degassing. The high-shear design achieves melt temperatures of 180-230°C with ±3°C uniformity.
Die Design: Multi-cavity spiral die enabling simultaneous production of 2-4 smaller pipes (e.g., two DN315 pipes) or single large-diameter pipes, reducing floor space by 40% compared to multiple single-cavity systems.
Vacuum Calibration Tank: Stainless steel construction with adjustable water flow (10-50 m³/h) and multi-zone vacuum control (0.03-0.09 MPa). Equipped with precision guide rails and adjustable spray nozzles for uniform cooling.
Hauling Unit: Hydraulic-driven caterpillar with 12-24 pairs of rubber-coated rollers that provide 50-200 kN traction force with synchronized speed control (±0.2% accuracy) to prevent pipe ovality.
Cutting System: Plasma cutting with CNC-controlled positioning (±1 mm accuracy) for large diameters, with a circular saw option for smaller pipes. Includes automatic debris collection and dust suppression.
PLC+HMI Interface: 19-inch industrial touchscreen with real-time monitoring of wall thickness (via ultrasonic sensors, ±0.5% accuracy), melt pressure (0-30 MPa), and production output (kg/h, meters/h). Supports remote diagnostics and production data logging.
Safety Features: Overload protection for motors and gearboxes, emergency stop buttons at all operator stations, and safety interlocks on all access panels. Includes fire suppression system for the extrusion zone.
Water Supply
Manufactures DN300-DN1200 mm HDPE pipes for municipal water mains and distribution networks, with corrosion resistance (ASTM G31, 1000-hour salt spray test) eliminating the need for protective coatings.
Supports fusion welding (ISO 21307) with heat fusion joints that achieve 100% of pipe strength, ensuring leak-free operation with service life ≥50 years.
Natural Gas Transmission
Produces DN400-DN2000 mm high-pressure gas pipes (PN16-PN25) complying with CSA B137.5 and EN 1555, with excellent resistance to gas permeation (≤0.1 cm³/m·h·bar).
Manufactures distribution pipes for residential and industrial gas supply, with impact resistance (≥20 kJ/m² at -20°C) to withstand ground movement.
Mining Industry
Processes abrasion-resistant HDPE pipes for slurry transport in mining operations, with wear resistance (ASTM D4020) exceeding steel pipes in many applications.
Creates chemical transport pipes for mining effluents, resistant to acids, alkalis, and heavy metals per ISO 12162.
Irrigation Systems
Constructs large-diameter agricultural pipes (DN200-DN630 mm) with smooth inner surface (Ra ≤0.4 μm), reducing friction losses by 15% compared to concrete pipes and improving water distribution efficiency.
Supports micro-irrigation mainlines with precise wall thickness control for uniform pressure distribution.
Q: What is the maximum working pressure of the HDPE pipes?
A: The extruder produces pipes rated for PN25 (25 bar/2.5 MPa) for gas applications and PN16 (16 bar/1.6 MPa) for water applications, with pressure ratings verified through hydrostatic testing (ISO 1167-1).
Q: Can it handle recycled HDPE materials?
A: Yes, with an upgraded screen changer (200-mesh filtration) and high-shear mixing elements, it efficiently incorporates up to 50% recycled HDPE content in multi-layer pipes. Mechanical properties are maintained through strict quality control and testing.
Q: What is the energy consumption per ton of pipe?
A: It achieves 0.35-0.45 kWh/kg (350-450 kWh per ton) through the use of IE5 ultra-premium efficiency motors, regenerative drives that recover energy during braking, and heat recovery systems that reuse waste heat from extrusion cooling.
Q: How does it ensure uniform wall thickness for large-diameter pipes?
A: The system uses laser scanning technology with 360° measurement (100 data points/second) combined with closed-loop control of the die lip position, maintaining wall thickness tolerance within ±5% of nominal value—exceeding ISO 4427 requirements.
