摘要
An object of the present invention is to provide a vent pipe isolation balloon for a liquefied gas storage tank, which has excellent physical strength, inflatability, and durability at cryogenic temperatures, and a vent pipe isolation device including the balloon. The vent pipe isolation balloon of the present invention has inner and outer membranes made of silicon rubber, and a reinforcing substrate sandwiched between the inner membrane and the outer membrane. The balloon has an outer shape of a cylindrical shape or a truncated cone shape with both ends opened, and is inflated when an inert gas is injected into the balloon with the openings sealed. The reinforcing substrate is composed of a fiber bundle and has a network structure.
