DESIGN OF FLANGES PART OF TANK DOME Russian patent published in 2014 - IPC B63B25/16 

FIELD: machine building.

SUBSTANCE: design (21) of flanged part of the tank dome includes: flanged part projecting outside from the external surface of side wall of the tank dome ensured at section of the main tank body, made with possibility to store LT liquefied gas; tank casing (6) with possibility to cover section of the main tank body with space (5) between them; and compensation rubber section (11) ensured between the flanged part (22) and casing (6) of the tank, and made with possibility to tight the space (5), at that section of the heat transfer suppressing material, i.e. fibre reinforced plastic, is ensured on at least specified section of the flanged part (22), at that specified section is located between the side wall (3a) of the tank dome (3) and compensation rubber section (11).

EFFECT: temperature decreasing of LT liquefied gas stored in the tank upon ambient temperature rise due to the heat-insulating materials.
