TANK WALL CONTAINING SEALED MEMBRANE HAVING CORRUGATION WITH ENHANCED CURVILINEAR SECTION Russian patent published in 2022 - IPC F17C13/00 B65D90/02 B67D9/00 

FIELD: storage.

SUBSTANCE: group of inventions relates to tank wall (1). The wall includes heat-insulating barrier (2) and sealed membrane (3) resting against heat-insulating barrier (2). Sealed membrane (3) includes a corrugation having curvilinear section (36) developed in curvilinear direction (d₁) and one curvilinear enhancing device (37) located in curvilinear section (36) between sealed membrane (3) and heat-insulating barrier (2) for enhancing mentioned curvilinear section (36). Curvilinear enhancing device (37) includes a set of enhancing sections (42, 43, 44), each of which has a profiled shape developed in rectilinear direction (d₂, d₃, d₄). Curvilinear enhancing device (37) additionally includes connecting element (45) connecting mentioned enhancing sections (42, 43, 44) for retention of then in a position, in which rectilinear direction (d₂, d₃, d₄) of each of enhancing sections (42, 43, 44) is oriented tangent to curvilinear direction (d₁).

EFFECT: enhancing a tank wall.
