  • Method and apparatus for pressurizing hot-isostatic pressure vessels
    Patent number: 4032337
    Abstract: A method and apparatus for the rapid, high-capacity pressurization of hot-isostatic pressing vessels, specifically of the type adapted for the hot-isostatic pressing of alloy shapes from powder metallurgy alloy charges. This is achieved by pressurizing with argon gas which is obtained by pumping cryogenic liquid argon at relatively low pressure to a relatively higher pressure and vaporizing said pumped liquid argon to produce said gas, which gas after use in the vessel for compacting is reclaimed and reliquefied for reuse.
