HEAT-INSULATING SEALED TANK Russian patent published in 2021 - IPC F17C3/02 

FIELD: containers.

SUBSTANCE: group of inventions relates to a sealed and heat-insulating tank built into a load-bearing structure. The tank comprises an auxiliary sealing membrane (4, 104), multiple tank belts made of an alloy with a low expansion coefficient. The tank also comprises a main sealing membrane (6, 106) containing metal plates with first parallel corrugations (56, 156) and second corrugations (55, 155) perpendicular to the first corrugations. The auxiliary metal beam (30) located parallel to the rib (100) comprises a first flat wing (31) parallel to the first load-bearing wall, and a second flat wing (321, 322) parallel to the second load-bearing wall, welded whereto is the end section of the auxiliary sealing membrane (4, 104). The main angular component comprises a metal angular element (42), welded whereto is the end section of the main sealing membrane (6, 106). The retaining elements (15, 45) retain the main angular component and pass tightly through the auxiliary sealing membrane (4, 104).

EFFECT: creation of a tank with a more durable structure, simpler in manufacture.
