What Is Long Venturi Nozzle?
A long venturi nozzle is an abrasive blasting nozzle with a longer converging–diverging (venturi) bore than a standard venturi or straight-bore nozzle. The extended profile increases particle velocity and widens the blast pattern, improving cleaning speed on large surfaces when air volume is adequate.
Long Venturi Nozzle for Sand Blasting Machine is used on portable pots, blast rooms, shipyards, and fabrication yards where operators need higher production rates than a straight bore nozzle can deliver.
How Does Long Venturi Nozzle Work?
Compressed air carries abrasive media through the blast hose into the long venturi orifice. The converging inlet accelerates the mix; the longer diverging outlet lets particles reach higher exit velocity before they strike the workpiece. The result is a more productive blast pattern and faster rust or coating removal on large steel areas.
When the orifice wears and widens, cleaning slows and air demand rises. Replacing a worn long venturi nozzle restores blast speed, pattern control, and compressor efficiency.
Types of Long Venturi Nozzle
Long venturi nozzle selection depends on orifice size, liner material, holder thread, hose length, and compressor CFM.
Tungsten Carbide Long Venturi Nozzle
The everyday production choice for contractor and fabrication blasting with a long venturi profile.
Tungsten Carbide Long Venturi Advantages
- Balanced wear life and cost for industrial blasting
- Stable orifice for consistent production rates
- Fits common nozzle holders and blast hose assemblies
- Practical stocking nozzle for contractor fleets
Boron Carbide Long Venturi Nozzle
Selected for aggressive media and continuous high-throughput blasting where orifice life must be maximized.
Boron Carbide Long Venturi Benefits
- Longer wear life under garnet and aluminum oxide
- Fewer nozzle changes on multi-shift jobs
- Preferred for shipyard and heavy fabrication duty
- Maintains blast pattern accuracy for longer service intervals
Long Venturi Nozzle Kits
Supplied with matched holders, gaskets, and couplings for fast pot-to-nozzle installation.
Common Long Venturi Kit Applications
- Complete nozzle and holder assemblies for portable pots
- Replacement long venturi tips for existing holders
- Export spare packs with mixed orifice sizes
- Project stocking for shipyard and plant blasting crews
Benefits of Using Quality Long Venturi Nozzle
- Higher productivity: Extended venturi profile increases particle velocity and cleaning speed.
- Wider blast pattern: Covers more surface area per pass on large steel work.
- Material options: Tungsten carbide, boron carbide, silicon carbide, and ceramic liners.
- Holder compatibility: Fits standard sand blasting nozzle holders and blast hose.
- Export ready: Supplied individually or in kits for India and worldwide projects.
Long Venturi Nozzle for Sand Blasting
For sand blasting, grit blasting, and coating removal on large structures, a long venturi nozzle is the high-production choice when compressor CFM and hose length can support the profile. It pairs with nozzle holders, blast hose, couplings, and pinch valves for complete blasting circuits. We also supply straight bore nozzles, tungsten carbide nozzles, boron carbide nozzles, nozzle holders, and blast hose from India.
Choosing Reliable Long Venturi Nozzle Manufacturers
Confirm orifice size, liner material, holder thread, hose length, and compressor CFM. A reliable manufacturer helps match long venturi nozzles to your air supply so the extra profile actually improves production instead of starving the nozzle.
