How to Choose the Right Blast Nozzle for Wet Abrasive …
Some manufacturers produce their own composite carbide nozzles which are even harder than boron carbide. Nozzles are not cheap to replace. One benefit of vapour abrasive blasting is that your nozzles will last up to 3x longer than a dry blasting nozzle because the particles are enclosed in a lubriing water jacket, which reduces friction between the abrasive and the nozzle lining.
