Abstract
PURPOSE: To prevent excessive friction from occurring between an inner membrane tank and a heat insulator etc. when the inner membrane tank is cooled and contracts, by applying to the outside surface of the inner membrane tank a pressure which resists the vapor pressure of a coolant introduced and evaporated in the inner membrane tank.
CONSTITUTION: The pressure, which resists the vapor pressure of the coolant introduced and evaporated in the inner membrane tank 4 facing an outer tank across the heat insulator 3, is applied to the outside surface of the inner tank 4 to prevent the excessive friction from occurring between the inner tank and the heat insulator. For example, nitrogen gas is filled on the inside and outside surfaces of the inner membrane tank 4. Then, liquefied gas is introduced as the coolant into a pipe 8 and ejected from a nozzle 8' to previously cool the inner tank 4 by the latent heat of vaporization. At the same time, nitrogen gas of appropriate pressure is supplied from a pressure pipe 10 to the outside surface of the inner membrane tank 4 to balance the pressure inside the inner tank 4 to that outside it
