ABSTRACT:
Cryogenic insulation seal for a concrete container, having an inner cryogenic liquid tank, comprising a concrete floor slab, a vertical concrete wall moveably supported on the concrete floor, and insulation positioned within the container adjacent the horizontal floor slab and the vertical concrete wall, and including a metal, e.g. steel, liner positioned around the inner surface of the container, adjacent the inner surfaces of the floor slab and the concrete wall and supporting the insulation, and forming an inner seal around the container. The steel liner is inclined from the vertical at a corner above the floor slab and is attached to the vertical concrete wall at a predetermined height above the floor slab, forming a gap between the liner and the concrete vertical wall at the corner, and permitting inward lateral motion of said vertical wall with respect to the floor slab at such corner, while permitting the steel liner and the insulation supported by the liner to flex and maintain a seal at the corner.
