Uses air, nitrogen, or an inert gas as the medium. It is typically performed at 1.1 times the MAWP. Because compressed gas stores a massive amount of potential energy, it poses a severe blast hazard and is only used when water cannot be tolerated (e.g., due to refractory linings, catalyst contamination, or structural load limits).
