Welcome to ZIBO LONGSHINE
Boron carbide venturi sandblasting nozzle
Longshine boron carbide Venturi sandblasting nozzles are engineered for maximum blasting efficiency, long service life, and consistent surface results. Made from boron carbide (B₄C) — one of the hardest known materials, second only to diamond — these nozzles deliver superior wear resistance, stable airflow, and lightweight handling for demanding industrial applications.
Features
Material: Boron carbide (B₄C) — ultra-hard, lightweight, and extremely wear-resistant.
Venturi Structure: Converging–diverging design accelerates abrasive velocity by up to 60%, increasing productivity.
Precision Machined Bore: Ensures stable air pressure and consistent abrasive flow.
Lightweight Construction: Easier handling and less operator fatigue compared with tungsten carbide nozzles.
Thread Types: Available in 50 mm or 1-1/4" NPSM threads; customized types available.
Advantages
Ultra Wear Resistance: 5–10× longer lifespan than tungsten carbide nozzles.
High Blasting Efficiency: Venturi design provides wider spray pattern (25°–35°) and faster cleaning rate.
Energy Saving: Reduced air and abrasive consumption compared with straight bore nozzles.
Stable Performance: Maintains consistent jet pressure and pattern over long-term use.
Cost-Effective: Higher initial cost but lower lifetime cost per hour due to extended durability.
Compatible Abrasive Media
Suitable for almost all standard blasting abrasives, especially hard and aggressive materials:
Aluminum oxide (corundum)
Silicon carbide
Steel grit / steel shot
Glass beads
Garnet
Copper slag
Plastic media (for delicate surfaces)
⚠️ Not recommended for very soft abrasives like soda or organic media, as they may cause uneven wear.
