Hot Pressed Boron Carbide Wide Throat Sandblasting Nozzle 50x12mm B4C Large Bore Blast Tip

The B4C-WT50-12 wide throat sandblast nozzle is engineered for maximum productivity in large-scale surface preparation operations. With a 12mm orifice and 50mm venturi-angled bore, this nozzle delivers abrasive flow rates up to 800 kg/hour, making it ideal for bridge maintenance, ship deck blasting, and industrial tank lining removal.

Large bore nozzles face extreme wear conditions due to the high volume of abrasive passing through the orifice. Hot pressed B4C is uniquely suited to this challenge because:

• Uniform density throughout the entire nozzle body ensures consistent wear patterns, preventing the uneven bore enlargement that causes premature venturi profile degradation
• High thermal conductivity (30-42 W/m*K) dissipates frictional heat generated by high-volume abrasive flow, reducing thermal stress microcracking
• Chemical inertness prevents reaction with moisture or contaminants in recycled abrasives, maintaining bore surface integrity

Compared to conventional straight bore and standard venturi nozzles, the wide throat design provides:

• 2x the abrasive flow rate of a standard 10mm venturi nozzle at the same pressure
• Wider blast pattern for faster coverage of large surface areas
• Reduced clogging risk with recycled or damp abrasives due to the enlarged feed throat

In 12mm orifice nozzles, material choice is critical because wear volume scales with the square of the orifice diameter. Our testing shows:
