ABSTRACT:
A cryogenic container adapted to store or transport liquified gases, the container including an outer tank formed by walls which have thermal insulation properties and are structurally capable of supporting the load, the walls incorporating a liquid and gas-impervious secondary barrier. Received within the outer tank and readily removable therefrom is a prefabricated independent inner tank constituted by a flexible bladder whose geometry roughly conforms to the contours of the inner surface of the outer tank. The bladder is formed of a synthetic plastic fabric material that is coated to render it liquid and gas-impervious to define a primary barrier, which coated fabric material maintains its flexibility and other physical characteristics at cryogenic temperatures and has sufficient structural strength to sustain the cryogenic liquid load without any danger of rupture even in those areas thereof in which the bladder does not fully conform to the contour of the outer tank surface and is not backed thereby.
