International ClassesA62D 003/00B08B 003/02 AbstractDescribed is a method of removing explosive agents from the interior of explosive agent filled bodies such as munitions shells. A rotating nozzle is inserted into an opening cut into the shell. Ultra-high pressure fluidjets (i.e. above 40,000 psi) are projected from orifices in the nozzle onto the explosive agent in the shell. Explosive agent and explosive agent laden fluid is contained and carried away from the shell for recycle or disposal.Field of SearchProcessIncluding melting With pressurized fluid or fluid manipulation With organic treating agent (e.g., solvent, surfactant, or reactant yielding soluble product, etc.) Movable fluid applying nozzle and/or with plugging or sealing of work passage or opening Work or work parts movable during treatment | |
