AIRTIGHT AND ISOTHERMAL TANK CONTAINING METAL MEMBRANE WITH CORRUGATED ORTHOGONAL FOLDS Russian patent published in 2018 - IPC F17C3/02 B63B25/16 

FIELD: machine engineering.

SUBSTANCE: airtight and isothermal tank is integrated into the structure with a supporting wall (3), to which the wall of the tank adjoins. A heat-insulating barrier is mounted on the supporting wall (3) and is formed by insulating blocks (1) in the form of rectangular parallelepipeds arranged in parallel rows separated from each other by gaps (10). The sealed barrier is mounted on a heat-insulating barrier and comprises a metal membrane made of metal sheets (11) hermetically welded to each other. On surface of each insulating block of the heat-insulating barrier opposite the supporting wall (3) are at least two predominantly orthogonal connecting metal strips (5, 6). They extend parallel to the insulating block sides and are welded to the sheets (11) of the metal membrane installed on the insulating block. At that, the connecting strips are rigidly connected to the insulating block on which they are arranged. Each of the plurality of sheets (11) of the metal membrane comprises at least two orthogonal folds (12a, 12b) parallel to the sides of the heat insulating blocks (1) and placed in the gaps (10) between the insulation blocks. A ship for transportation of a cold liquid product having a double housing inside which the above-described container is mounted. Use of the ship for the purpose of loading or unloading a ship by supplying a cold liquid product through insulated pipes from a shore or a floating storage to the ship tank or to the shore or floating storage tank from the ship tank. System for transporting cold liquid product comprising above-described ship, insulated pipes connecting the tank mounted in the ship hull with shore or floating storage, and a pump to supply cold liquid product through isolated pipes from or to floating or shore storage to or from the ship tank.

EFFECT: improved airtightness.
