Key Features and Benefit

High L/D ratio single-screw extrusion: Screw L/D ratios typically exceeding 35:1 with barrier designs and efficient mixing sections deliver high melt strength and uniform plasticization for HDPE, enabling high-output production of large-diameter pipes while lowering melt temperatures to minimize degradation.

Advanced vacuum calibration technology: Multi-stage vacuum tanks with internal cooling precisely control wall thickness distribution, enhancing ring stiffness and reducing internal stresses for superior structural integrity in high-pressure applications.

Online monitoring and intelligent control: Ultrasonic or laser thickness measurement integrated with PLC feedback loops enables real-time parameter adjustments, significantly improving dimensional accuracy and reducing scrap rates in long-run productions.

Chipless cutting and haul-off systems: Planetary or rotary cutters paired with servo-driven haul-off ensure clean, burr-free cuts and precise length control, particularly beneficial for large-diameter pipes to eliminate secondary processing.

Modular downstream configuration: Flexible additions for co-extruded marking stripes, internal coatings, or multi-layer composites accommodate specific needs like gas pipes or enhanced protection, with optimized water recycling for resource efficiency.

Primary Applications

Municipal Water Supply Systems: For potable water distribution pipes, ensuring safety, pressure resistance, and leak-proof performance.

Gas Transmission Pipelines: Suitable for natural gas distribution, offering high pressure tolerance and corrosion resistance.

Sewage and Drainage Systems: In urban wastewater and stormwater pipes, handling heavy loads and chemical exposure.

Agricultural Irrigation: Applied in farmland water supply and drip systems, lightweight and weather-resistant for easy deployment.

Industrial Fluid Conveyance: For chemical, mining, and industrial wastewater lines, resisting corrosion and abrasion.

Cable Protection Conduits: As sheathing for power and telecommunication cables, providing insulation and mechanical protection.

Infrastructure Construction: In road drainage, bridge piping, and underground projects, ensuring longevity and low maintenance.

In summary, pipes produced by the HDPE pipe extrusion line are renowned for corrosion resistance, flexibility, and high strength, serving as ideal alternatives to traditional metal or concrete pipes across water supply, gas, drainage, and industrial sectors for efficient, cost-effective, and environmentally sustainable solutions.
