An upright tank of cylindrical or prismatic form has a sealed inner wall surrounded by insulation, and an outer casing. The bottom of the inner wall is formed from parallel strips of INVAR welded together at inturned flanged edges and is mounted in sliding relation to insulation beneath the bottom. The inner side wall is formed from parallel vertical bands of stainless steel with inwardly bent margins welded together and slidingly supported vertically to permit expansion and contraction. The inner side wall is joined to the inner bottom wall by a corner angle assembly including sheets and angles of INVAR supported by an annular beam. The annular beam includes straight beam sections supported at their ends by gussets which in turn are anchored to the exterior casing of the tank.
