Why Silicon Carbide Nozzles Lose Blast Efficiency Long Before They Fail After twelve years supporting abrasive blasting operations, a common complaint is that production rates decline and surface profiles become inconsistent even though the compressor and abrasive feed appear unchanged. The change is usually progressive enlargement of the nozzle orifice. Once the bore diameter increases, air volume required to maintain pressure rises, exit velocity falls, and the blast pattern spreads. Silicon carbide liners resist this wear better than many alternatives, yet they are not immune.
