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.
