Abstract: Tank for use in storing low temperature liquefied gas comprising a rigid outer vessel, a thin film inner vessel with rigid partition walls, and a heat insulating layer inserted between these two vessels. Each of the partition walls extends through the inner vessel and is slidably supported by the outer vessel to permit expansion and contraction of the partition walls. The thin film inner vessel walls are secured to the partition walls at points near where the partition walls pass into the heat insulating layer to form a closed vessel having a large capacity.

Abstract: A tank for use in storing low temperature liquefied gas having a rigid outer vessel lined with a heat insulating layer and an inner vessel of a thin film construction with gently undulated camber. The peripheral dimensions of the material of the inner vessel are made relatively larger than those of the inner peripheral dimensions of the insulating layer of the outer vessel. The camber serves to relieve the hoop stress acting upon the inner vessel when it is subjected to the load resulting from the low temperature liquefied gas.

Abstract: A low-temperature liquefied gas storage tank comprising an outer tank made of rigid metals and an inner tank having a thin film construction. The inner tank is provided at its upstanding peripheral inside surface with vertically extending corrugations and includes means for suspending its upper peripheral edge so as to permit contraction and expansion of the inner tank when it is subjected to a liquid load or exposed to a low temperature. The inner tank prevents undesirable cracking and damage thereof and can store the low-temperature liquefied gas in a safe manner.
