Tank for use in storing low-temperature liquefied gas
Abstract
Abstract A tank for use in storing low-temperature liquefied gas has an inner vessel composed of a thin film construction suspended from the top wall of an outer vessel, and is constructed so that corrugations vertically formed on the sidewall of said inner vessel may be contracted under the low-temperature loaded condition to approach a smooth configuration in close contact with a heat-insulating layer provided between said outer and inner vessels. At the curved bottom corner of said inner vessel, an increase in length is produced along the outer top part of each corrugation due to the difference in length between the outer top part and inner top part of each corrugation, and said increased length appears as an additional corrugation. To prevent collapse of the additional corrugation, when the vessel is loaded, a part of the heat-insulating layer is eliminated to form a recess for the outer part of the additional corrugation, thereby providing it with a smooth deformation.
