Abstract
Abstract 728,423. Storing liquefied gases; securing pipes in casings. UNION CARBIDE & CARBON CORPORATION. July 17, 1953 [Sept. 12, 1952], No. 19926/53. Classes 8 (2) and 99 (1). In a container for storing liquefied gases below 275‹K. comprising an inner vessel A, Fig. 1, and an outer shell B spaced by heat insulating material 10, the inner vessel A has a vertical side wall 11 of prestressed reinforced concrete maintained in a state of compression when in contact with liquefied gas by tension members e.g., steel wires 12, 13 encircling the wall. The vessel cover 14 is of concrete reinforced by a metal screen 14<SP>1</SP> (not shown) and prestressed by wires 11<SP>1</SP>, and the wall rests on a reinforced concrete footing ring 15 supported by layers of foamed glass, a concrete slab 17, a layer 18 of sand, and earth 19 maintained above freezing point by heater tubes 29. The vessel floor 20 is of concrete containing entrained air .and supports a steel liner 21 welded to an upstanding flange 23 carrying at its upper rim a steel bar 24 embedded in the wall 11. The flange 23 may be of steel, copper, copper alloy, aluminium or aluminium alloy of high impact strength at low temperatures. The shell cover 26 is of concrete and the outer shell wall 25 which is of prestressed reinforced concrete extends below ground level to rest on a foundation 27. A vapour outlet duct includes an'expansion joint 40 within the insulation 10 and connecting pipes 38 each of which passes through a steel sleeve 51, Fig. 6, lining coaxial apertures in the covers 14, 26; the ducts 38 being welded to the sleeves 51 by conical steel frustra 52. A drain 31 and overflow 34 are similarly mounted in the wall 25 and a manhole 41 comprises steel sleeves 42, 43 bonded to the covers 14, 26 and connected by a corrugated tube 44. In a modification the flange 23 extends as a lining up the wall 11 and the wall 25 is supported above ground level by a concrete slab resting on piers projecting from the earth.
