METHOD OF PRESSURISED CYLINDER DISPOSAL Russian patent published in 2013 - IPC B26F3/02 B23D27/00 F42B33/06 

FIELD: process engineering.

SUBSTANCE: invention relates to disposal of used pressurised cylinders by ram loading. Proposed method is based on application of ram engine. Cylinders to be disposed are rigidly secured at the armored box base to apply pulsed impact load to cylinder body by ram engine tapered hammer for initial destruction of cylinder body wall. Further destruction is made by the pressure of cylinder gases. Ram engine drop speed is defined by the relation: $$V=\sqrt{\frac{({\sigma }_{т}+{\sigma }_{в})\cdot {\epsilon }_{в}}{m}\cdot \pi \cdot {\delta }^3\cdot t{g}^2\left(\frac{\alpha }{2}\right)},$$ where m is ram engine weight; α is apex angle of ram engine hammer; δ is cylinder wall thickness; ε_B is failure strain of cylinder material; σ_B is material durability; σ_T is material yield point.

EFFECT: simplified disposal process.
