A freight container includes a cylindrical tank disposed within an outer frame. The tank is connected to the corner regions of the frame by means of eight saddle pieces which have curved borders welded to tensioning rings surrounding the tank near the ends thereof. Each tensioning ring is composed in the peripheral direction of the tank of two sections clamped together by tensioning screws and locked in both axial directions of the tank by a plurality of sheet metal pieces welded to the tank shell on both sides of each tensioning ring. The tank may be detached from the frame by loosening the tensioning screws whereupon the tensioning rings may be raised over the sheet metal pieces in axially moving the frame relatively to the tank. In assembling the freight container, the metal pieces are welded to the tank in the final manufacturing step after the tank and the frame have been positioned relatively to each other with the required dimensional accuracy. |
