Sandblasting nozzles for abrasive blast cleaning

Sandblasting nozzles

Everblast™ Established, in 2002 in Illinois, brings over 19 years of dedicated focus to engineering, building & supply of quality carbide sandblasting nozzles. We provide maintenance industry with blast cleaning nozzles constructed using quality wear resistant carbide liners. Our grit blasting nozzles / sandblasting nozzles / blasting nozzles / Cabinet nozzles / inserts are made using wear resistant carbide liners including: boron carbide, Silicon carbide, Sylacon (Silicon Nitride) and tungsten carbide. We also work with clients on making custom carbide inserts and carbide nozzles.

Sandblasting nozzles are used to accelerate and/or focus abrasive stream to: (1) Clean surfaces and/or (2) create an anchor pattern or profile so that a coating can adhere to metal surface. A wide variety of steel surfaces need to be blast cleaned before painting, e.g. Bridges, locomotives, rolling stock, silos, tanks, petrochemical plants, oil rigs, military equipment, boats / shipyards and bodyshops. Then there are smaller or more delicate parts that need to be blast cleaned e.g. aircraft outer surfaces to clean off old paint, electronic parts, fiberglass products, engines and transmissions. Dentists use small nozzles to spray bicarb of soda solution on to teeth! Think of a surface and nearly all need some form of abrasive cleaning.

Some examples of Sandblasting, media blasting or grit blasting methods that use carbide blast cleaning nozzles, are:

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 hazardous contaminants.
Vapor blasting where the water mixing with abrasives is controlled and reduces run off.
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
Monument cleaning
Glass and stone etching
bead blasting

Many of our quality carbide sandblasting nozzles, incorporate venturi geometry to increase abrasive output speed. Everblast's contractor style sandblasting nozzles (grit blasting nozzles, sandblasting nozzle tips) are supplied with contractor style, industry standard threads: 1-1/4" NPSM threads and coarse 2" /metric/ contractor threads. High production carbide sand-blasting nozzles are available with either 1" (25mm) or 1-1/4" (32mm) entry.

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 carbide nozzles with 3/4" NPSM threads that use a 3/4" NPSM 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 sandblasting 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" NPSM 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 cleaning probe for blast cleaning inside small (narrow) 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)
Ceramic	20-40	10-30	1-4
Tungsten Carbide	500-800	300-400	20-40
Silicon Carbide/Silicon Nitride	600-1000	400-600	50-100
Silicon Composite	1400-2300	700-1450	180-900
Boron Carbide	1500-2500	750-1500	200 - 1000
