Tungsten Carbide Sandblasting nozzles
Everblast's carbide abrasive blast nozzles, grit blasting nozzles and sandblasting nozzle tips are supplied with a choice of industry standard threads from the fine 1-1/4" threads, more commonly used in USA to coarse 2" threads widely used outside North America.. Most long venturi carbide sand-blasting nozzles are available with either 1" (25mm) or 1-1/4" (32mm) entry. We offer a wide range of carbide inserts: tungsten carbide, boron carbide and ceramic - These inserts are generally used in suction guns operated in sandblasting cabinets and workshops where close up blast cleaning is needed.
We offer a choice of different jackets to protect carbide liners these range from our 100% armored jackets that incorporate an alloy jacket and threads to provide maximum protection against ricochet and impact to lighter weight plastic jackets that provide good impact protection for the liner.
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. Nozzles available with either 1-1/4" fine threads or 2" coarse threads.
To maximize productivity of abrasive blast cleaning system it is important to select a carbide nozzle that will be cost effective when used with a specific media. It is important to use a sand blasting nozzle with bore to suit compressed air supply and required nozzle exit velocity. Nozzles should not constrict air and abrasive flow by going from a larger hose I.D. to a smaller nozzle entrance size.
There are many different types of blasting media from walnut shells, plastic, ice, sponge, Soda, copper slag, garnet to steel shot. The work that is being performed and surface finish needed deteremines type of media that should be used.
Tungsten carbide nozzles are the most commonly used nozzles in the sandblasting / abrasive blast cleaning industry. They are tough and are best suited for use in harsh work site conditions. Tungsten carbide nozzles are economical and work well with most abrasives. If you want light weight carbide nozzles for use with the same media we offer Silicon carbide blast cleaning nozzles. Cost is higher than a comparable tungsten carbide nozzle but Silicon carbide offers a longer wear life.
Wet blasting has become more popular over the years as this method offers a way of controlling dust. 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 and any coatings that may subsequently be applied.
Sandblasting nozzles and ceramics are available through our network of domestic and international distributors. Everblast Distributors focus on the abrasive blast cleaning industry and carry a range of sandblasting equipment and supplies e.g. compressors, sandblasting hose, couplings, nozzle holders, sandblasting abrasives, blast pots, blast hose, cabinets, replacement parts for sandblasting equipment, sandblast helmets, replacement lenses and other sandblasting related supplies and equipment. If you are looking for a distributor please call us.
Another area of sandblasting where carbide is used, is in sandblasting cabinets, blast cabinets and sand blaster guns. These carbide inserts come in many different sizes and shapes so sandblast machine operators have to check carefully when purchasing replacement inserts and purchasing used sand blasting machines.
We also supply a range of light duty ceramic nozzles / inserts for sandblasting.
What are ceramic nozzles? They are light duty alumina abrasive blast cleaning - etching- nozzles generally used in cabinets and anywhere a small blast pot is used for example spot cleaning of small parts. Ceramic nozzles have a much shorter work life than e.g. tungsten carbide.
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|
