Insulated tank assembly with insulation stop and method of assembly thereof

摘要

An insulated tank assembly with insulation stop and a method of constructing such an assembly. The assembly includes an inner tank with an outer shell located in spaced relation to and surrounding the inner tank, creating at least one annular clearance space between the tank and the shell. The space is closed by a sealing device that includes a circumferential sealing strip having an unstretched strip length that is less than either the continuous outer top edge length or the continuous outer bottom edge length, or both, of the strip. Such length relationships make the sealing strip both resilient and resistant to rolling during construction of the assembly. The sealing strip may be a fibrous strip. The tank assembly may be insulated by placing insulating material within the at least one annular clearance space, which may be a foamable insulation material, foamed in place within the annular clearance space.
