High-Pressure Wear-Resistant Tungsten Carbide Square Nozzle
Product Overview
The square tungsten carbide (WC) nozzle is manufactured from high-purity tungsten carbide, designed for high-pressure and high-wear applications. It offers extended service life, superior wear and corrosion resistance, and precise spraying performance, making it ideal for waterjet cutting, sandblasting, industrial coating, and other demanding operations.
Key Advantages
1. Superior Properties of Tungsten Carbide
Tungsten carbide (WC) is the premium material for nozzles, outperforming standard steel or ceramics:
- Extreme Hardness (HRA 90-93): Second only to diamond, providing exceptional resistance to abrasive particles.
- Cavitation Resistance: High density (14-15 g/cm³) minimizes damage from bubble collapse in high-pressure liquid flows.
- Chemical Stability: Resistant to acids, alkalis, and oxidation, suitable for corrosive environments.
- High Thermal Conductivity (80-110 W/m·K): Efficient heat dissipation prevents thermal deformation.
2. Precision Manufacturing Process
- High-purity tungsten carbide powder with optimized cobalt (Co) binder (6%-12%) for balanced hardness and toughness.
- Hot Isostatic Pressing (HIP) technology eliminates internal defects, enhancing material density.
- CNC precision machining + mirror polishing, ensuring orifice tolerance within ±0.01mm for consistent flow.
3. Optimized Structural Design
- Square head for easy installation and alignment, compatible with mainstream spraying systems.
- Multiple spray angles available (15°, 30°, 45°, 60°) to suit different operational needs.
- Modular design allows quick replacement, minimizing downtime.
