摘要： An insulated tank for storage of liquids at low temperatures. The tank has an outer shell comprising a bottom, sidewalls, and roof, and an inner shell comprising at least a bottom and sidewalls, with or without an inner roof. The inner shell bottom is made of metal sheet or plate suspended from a plurality of spaced-apart supports resting on the bottom of the outer shell. The suspended inner shell bottom has a plurality of elongated corrugations of smoothly undulating contour with the valleys of the corrugations being between the supports, and a plurality of corrugations crossing and generally conforming to the smoothly undulating contour of said elongated corrugations. The corrugations accommodate the liquid load and contraction of the suspended inner shell bottom during low temperature use of the tank without substantial horizontal movement of said suspended bottom or its supports and without overstressing the metal sheet or plate of which the inner shell bottom is made. The tank also has insulating material beneath said suspended inner shell metal bottom, between the inner and outer sidewalls of the tank and beneath the roof.
