UHP Waterjet Nozzle (Mixing Tube) Technical Specifications
Our ultra-high pressure (UHP) waterjet nozzle (mixing tube) portfolio comprises multiple series engineered to deliver optimal balance of cost-effectiveness and operational efficiency for diverse industrial applications. Specifically engineered for UHP waterjet cutting systems, these nozzles feature micron-level orifice tolerances (±0.002mm) and radial concentricity <0.005mm, ensuring continuous process stability and repeatable cutting accuracy across extended operational cycles.

Manufactured through a vertically integrated production process, our nozzles undergo rigorous quality control from tungsten carbide powder metallurgy through:
- Isostatic pressing for uniform density distribution
- CNC contour grinding with 5-axis precision machining
- Electrical discharge machining (EDM) for final surface refinement
This comprehensive manufacturing protocol ensures consistent compliance with ASME B94.55M standards, achieving: - Vickers hardness ≥2200 HV30
- Surface roughness Ra ≤0.1μm
- Reconcile the two figures, e.g. “Service life of 80–200 hours depending on grade and application
Through continuous R&D investments in fluid dynamics optimization, we maintain industry-leading nozzle designs that maximize energy transfer efficiency (typically >92%) while minimizing kerf taper angle (<0.5° for 100mm thick materials).
