1,153,602. Liquefied gas storage containers. CHICAGO BRIDGE & IRON CO. 19 Oct., 1966 [15 Dec., 1965], No. 46837/66. Heading F4P. A liquefied gas storage container having an externally heat insulated metal base and a metal cylindrical side wall 50 has a fixed-position flat heat-insulated metal ceiling 63, 66 extending across the container and conforming at its periphery with the wall 50 above the highest liquid level; the ceiling being suspended from the metal roof 52 of the container, e.g. by three concentric circular courses A, B, C of spaced rods 61, 62. The roof 52 which is not insulated is formed of overlapping plates 53, 56, 57 and a peripheral ring 55. Flexible glass fibre insulation 67 is located between the container wall 50 and an L-sectioned metal ring 64 round the periphery of the ceiling. In a modification the insulated ceiling is supported on joists which are themselves suspended by rods from the roof. |
