THERMAL INSULATION OF RECEPTACLES FOR CRYOGENIC FLUIDS

摘要

This invention relates to the thermal insulation of reservoirs for cryogenic fluids with panels of a gas-tight thermal insulation material, bonded with an adhesive to the outer surface of the metal walls of said reservoirs. The tightness of the bond line between the tank wall and the insulating material is improved by uniformizing the material by heat curing, by coating the surface irregularities with an adhesive suited to a thick application at low temperatures, by reinforcing said adhesive with a cloth. The tightness of the bond line between the panels is improved by bevelling the panels so as to form between them a Y-shaped joint and sealing said joint by bonding a V-shaped closing tongue made of the same material.
