ABSTRACT:
In a double-walled tank for low-temperature liquids, such as liquid gas, an inner tank forming a primary safety casing is enclosed by an outer tank forming a secondary safety casing. The outer tank is constructed of reinforced concrete. A layer of thermal insulation is provided between the inner and outer tanks. The inside surface of the outer tank at least on the side wall and base is covered first by a vapor-tight layer and then by a layer of a liquid-tight thermal insulation material, preferably polyurethane foam.
