ANGULAR ELEMENT OF SEALED HEAT-INSULATED RESERVOIR FOR STORING FLUID Russian patent published in 2017 - IPC F17C3/02 

FIELD: oil and gas industry.

SUBSTANCE: reservoir comprises a secondary heat-insulating barrier fixed on a supporting structure, a secondary sealed membrane, a primary heat-insulating barrier and a primary air-tight membrane to be in contact with fluid contained in the reservoir. The angular structure comprises first and second panels forming an angular portion of the secondary heat-insulating barrier and having an outer side and an inner side; the angular structure in the secondary air-tight membrane structure is attached to first and second panels. The angular structure also comprises first and second insulating blocks in the primary heat-insulating barrier structure that are attached to the first and second panels respectively, and are adjacent to the angular structure of the secondary air-tight membrane. In addition, the angular structure comprises an angular portion in the primary sealed barrier structure having first and second arms which are attached to the first and second insulating panels, respectively. In this case, each of the first and second panels comprises a metal plate which secures its inner surface and carries a fastening component for fixing the heat-insulating block. The angular structure of the secondary air-tight membrane is made of metal and provided with channels for introducing fastening elements for insulating the blocks and is welded along the channels periphery to the metal plates bearing fastening elements to provide sealing of the secondary air-tight membrane.

EFFECT: creation of the angular structure suitable for assemblage.
