Abrasive Blasting Nozzles

Built to take the rigours of high productivity!
The Blast Nozzle is the business end of your blasting system. It is critical that you choose the nozzle you use correctly, as the size and type can effect your blasting production speed dramatically.

What Blast Nozzle lasts the longest?

Not all blast nozzles can last the same amount of time. The following paragraphs outline the different types of Blast Nozzles available and how long they all last.

SiNi Silicon Nitride

SiNi II Silicon Nitride nozzles are the longest last of the nozzles currently on the market with a tough polyurethane jacket which cushions the inner liner from misuse and from shattering while in job site conditions. When used with a high quality abrasive media like garnet a nozzle made from SiNi II grade Silicon Nitride will last over 500 hours.

Highly recommended that SiNi II Silicon Nitride nozzles should be used with the backing of blasting operators within the industry.

Tungsten Carbide

Tungsten Carbide Blast Nozzles are one of the most common nozzle used in the world. A typical tungsten carbide nozzle will last you between 100-250 hours of blasting, depending on what abrasive you are using. If you are looking for a nozzle to last longer then that, you should look into purchasing a Silicon Nitride lined blast nozzle.

Tunsgten carbide nozzles also are very brittle, so when blasters use them to communicate by banging them on a tank wall, they shatter, and need to be replaced.

Silicon Carbide

Silicon Carbide nozzles are a standard grade material that has a low life expectancy

Alumina

Alumina nozzles have the shortest service life of all the materials currently on the market.

Nozzle thread type effects the connection.

Thread types effect the hold between the housing and the nozzle by having the incorrect thread type the nozzle may:

  • Loose pressure
  • Higher wear levels on nozzle

The industry standard is the CONTRACTOR thread and is the most recommended when selecting a nozzle. The thread has a reduced chance of cross threading, easier to install and remove. With its increased thread depth the connection between nozzle and holder is much safer when used at higher pressures.

There is also the reduced change of binding/galling which is a form of wear caused by adhesion between sliding surfaces. When a material galls, some of it is pulled with the contacting surface, especially if there is a large amount of force compressing the surfaces together.

Industrial Thread Types

(F) Fine Thread

Second most common thread found on blasting nozzles and connections.

  • 2” UNC / 50 mm
  • 4 ½ Threads per Inch (TPI)
  • Measures 2” (51 mm) across threads
  • 1 ¼” NPSM / 32 mm
  • 11.5 Threads per Inch (TPI)
  • Measures 1 11/16” (42mm) across threads

(M) Medium thread

Most commonly found with Tite Space nozzles that require a high level of space saving.

  • ¾” NPSM / 20 mm
  • 14 threads per inch (TPI
  • Measures 1 1/16” (27 mm) across threads
  • 3/8” NPSM / 10 mm
  • 18 threads per inch (TPI)
  • Measure 11/16” (17 mm) across threads
