CYLINDRICAL SEALED UNIT FOR IMPROVING VAPORIZATION FACTOR OF LIQUEFIED GAS AND FRP-MADE CONTAINER FOR LIQUEFIED GAS

摘要

PROBLEM TO BE SOLVED: To provide a sealed unit for improving a vaporization factor of liquefied gas capable of improving the vaporization factor of liquefied gas in an FRP(fiber-reinforced plastic)-made container and the FRP-made container for liquefied gas. SOLUTION: In this cylindrical sealed unit, sealed in an FRP-made container for liquefied gas to be used for improving a vaporization factor of liquefied gas in the container, the cylindrical sealed unit for improving the vaporization factor of liquefied gas is characterized by making a cylinder part consist of material of heat conductivity higher than that of liquefied gas also consist of a hollow cylindrical unit closing both end parts of the cylinder part also making bulk density of the cylindrical unit smaller than density of the liquefied gas and a lower part of the cylindrical unit heavier than its upper part, in the case the unit is sealed in the container, generating a condition floated almost in perpendicular in the liquefied gas with a lower part of the cylindrical unit placed in a lower side, and the FRP-made vessel for liquefied gas is sealed with the cylindrical sealed unit.
