HIGH PRESSURE VESSEL FORMING METHOD Russian patent published in 2006 - IPC B21D51/24 

FIELD: plastic working of metals, namely manufacture of high pressure vessels from recovered ammunition.

SUBSTANCE: method comprises steps of producing blanks, subjecting them to hot deformation, hot molding of vessel mouths, mechanically working vessel mouths; subjecting articles to heat treatment for providing desired strength of vessels; using as blanks bodies of recovered artillery fragmentation type or high-explosive shells with removed collar; cutting each shell in joining zone of its ogival and cylindrical parts for preparing two blanks, namely cone blank with through opening and sleeve like blank with bottom. Heat treatment is realized according to preset mode.

EFFECT: lowered cost, improved factor of metal usage due to using recovered bodies of artillery fragmentation type high-explosive shells, enhanced quality of using shell steels.
