SEALED AND HEAT-INSULATING TANK Russian patent published in 2022 - IPC F17C3/02 

FIELD: sealing elements.

SUBSTANCE: group of inventions relates to a sealed and heat-insulating tank. The tank contains first wall (1) of the tank and second wall (2). Sealing membrane of first wall (1) of the tank contains the first row of parallel corrugations (7, 10) with uniform separation step (8). Sealing membrane of second wall (2) of the tank contains the second row of parallel corrugations (12, 14, 15) with specified uniform separation step (8), wherein each corrugation (7, 10) of the first row of corrugations (7, 10) continues with corresponding corrugation (12, 14) of the second row of corrugations (12, 14, 15). Sealing membrane of first wall (1) of the tank additionally contains individual corrugation (9) continuing parallel to corrugations (7, 10) of the first row of corrugations (7, 10). Corrugation (9) is located adjacent to the first row of corrugations (7, 9) and is separated from last corrugation (10) of the first row of corrugations (7, 10) by individual separation (11). Sealing membrane of second wall (2) of the tank additionally contains individual corrugation (16) continuing individual corrugation (9) of first wall (1) of the tank and containing the first relief capping cap. Last corrugation (15) relates to the second row of corrugations (12, 14, 15) and is offset from individual corrugation (16) of second wall (2) of the tank, containing second capping cap (21) hermetically closing specified last corrugation (15) of the second row of corrugations (12, 14, 15).

EFFECT: providing the possibility of the use of standardized elements for the manufacture of tank walls, while at the same time offering good tightness and good flexibility for secondary sealing membrane in corners of the tank.
