Sandblasting nozzles for abrasive blast cleaning
- Dry Blasting - using dry abrasives such as coal slag, garnet, aluminum oxide to clean and add profice to hard surfaces like steel.
- Soda Blast Cleaning - uses Formulated Bicarbonate of soda to clean softer surfaces e.g building walls.
Steel Grit Blasting - Uses steel grit, shot etc,
- Wet or slurry blasting. Used when dust control is needed especially when surface being blasted has contaminants in it that might be hazardous.
- Vacuum Blasting - used where containment is needed and recycling is considered a cost saver.
- Dry Ice Blasting - used in the aviation industry
- Ceramic / Pencil blasting
- Bead blast cleaning
- Peening - to add additional hardness to e.g. steel surfaces.
- Pipe blast cleaning
We offer a wide range of straight bore carbide inserts made from tungsten carbide, boron carbide or ceramic. These inserts are widely used in suction style blast cleaning guns. These are used where small parts or light blasting is needed e.g. in blast cabinets and/or workshops where close up blast cleaning is needed. We also make a range of armor jacketed short, straight bore boron / tungsten carbidenozzles with 3/4" NPSM threads that use a 3/4" threaded nozzle holder that it attached to the blast hose. Typically these fitted on small blast pots.
We offer a choice of different jackets to protect carbide liners. From our all armored alloy jackets and threads that provide a very high level of protection against ricochet wear and impact to lighter weight thermoplastic plastic jackets that provide good impact protection for liners.
Everblast makes a range of High performance XLBC blast cleaning nozzles these are great when large surface areas need blast cleaning and can be used for dry and wet blasting. These light weight nozzles are long venturi style with a boron carbide liner. Our Venturi Nozzles are available with either 1-1/4" fine threads or 2" coarse threads.
Of interest to many blasting professionals is our range of angle nozzles that help when blast cleaning in angles or difficult to reach area. These are available with one, two or three, 45 degree forward shooting exit ports. We also offer a 1/2" O.D. blast cleaing probe for blast cleaning inside small deep holes.
Wet blasting and soda blast cleaning has become popular as these methods offers a way of controlling dust - please see our range of Wet blasting nozzles. However, like many methods of blast cleaning there are pros and cons. It is important that each blast cleaning company researches to find out which method of blast cleaning (wet or dry) offers optimal results, given the type of surface preparation work being undertaken, abrasives used & coating that may subsequently be applied.
Blast cleaning media, flowing through a nozzle, will eventually wear away the nozzle bore. As bore size increases it gradually reduces sandblasting system's performance by increasing demand for air. In situations where no more air is available this will result in reduced abrasive exit velocity and reduction in blasting performance and increase in costs. It is important to check nozzles before start of every shift for bore wear and/or any damage.
Guide on Estimated Nozzle Service Life in hours.
All figures are indicative and given for nozzle comparison purposes only. Actual nozzle service life will depend on operational variables, such as blast pressure, media dimensions and media particle profile. All figures are approximate.
|Nozzle Liner Material||Steel/Grit Shot (hours)||Expendable Abrasives (Hours)||Aluminum Oxide (Hours)|
|Silicon Carbide/Silicon Nitride||600-1000||400-600||50-100|
|Boron Carbide||1500-2500||750-1500||200 - 1000|
