DESIGN OF CARGO TANK INSULATION FOR TRANSPORTATION OF LIQUEFIED NATURAL GAS AND METHOD OF ITS MANUFACTURING Russian patent published in 2012 - IPC F17C1/12 

FIELD: construction.

SUBSTANCE: cargo tank insulation comprises the first metal foil, attached and mounted between the upper insulation panel and the lower insulation panel, the second metal foil attached and mounted on the first metal foil. The second metal foil is located on the upper side of a gap formed between lower insulation panels. The upper bridge panel is attached and mounted on the upper side of the second metal foil. The method to produce a design structure provides for attachment of an adhesive film to the lower surface of the second metal foil, installation of the second metal foil onto a gap so that two opposite sides of the lower surface of the second metal foil are in contact, accordingly, with adjacent pieces of the first metal foil, installation of industrial equipment for engagement on the upper surface of the second metal foil and attachment of the second metal foil to the first metal foil by means of heating and pressing of the second metal foil by means of industrial equipment for provision of engagement.

EFFECT: higher resistance of insulation to multiple heat impact and increased strength of adhesion between insulation components.
