METHOD FOR PRODUCING SEALED AND THERMALLY INSULATING BARRIER FOR STORAGE TANK Russian patent published in 2018 - IPC F17C3/02 

FIELD: storage or distribution of gases or liquids.

SUBSTANCE: method for producing a sealed and thermally insulating wall for a fluid storage tank. Plurality of anchoring elements (1) are attached to load-bearing structure (2). Modular formwork elements (3) are installed on load-bearing structure (2), modular formwork elements (3) having a shape that protrudes relative to load-bearing structure (2) and defining, with load-bearing structure (2) and plurality of anchoring parts (1), plurality of adjacent compartments (4) having an open side opposite load-bearing structure (2). Each two adjacent compartments are separated by a modular formwork element placed therebetween. Insulating foam is sprayed into said compartments (4) through the open side so as to form a plurality of insulating sectors (5) made from sprayed insulating foam. Insulating junction elements (8) are arranged in a constrained position in which they are constrained between said insulating sectors (5). In order to ensure the continuity of the thermal insulation, they are capable of expanding in case of thermal contraction of said insulating sectors (5). Sealing membrane (9) is attached to said anchoring elements (1). Method comprising mounting on load-bearing structure (2) combined elements, each of which comprises modular formwork element (3) and constrained insulating junction element (8), placed in a stressed compressed state in modular formwork element (3). Method in which the modular formwork element (3) comprises two posts (27) which form an unfastened form and between which is in tension insulating junction element (8) and detachable means (28) for pressing posts (27) to insulating junction element (8) prior to detaching said means (28) for pressing the posts. Cryogenic fluid storage wall includes a load-bearing structure, a plurality of anchoring elements attached to it; plurality of insulating sectors (5) consisting of insulating foam formed by spraying insulating foam onto the load-bearing structure and firmly connected directly to load-bearing structure (2); insulating junction elements in a stressed state in which they are inserted between said insulating sectors, and capable of expanding in the event of contraction of insulating sectors; a sealing membrane attached to the anchoring elements. A vessel for transporting a cooled liquid product having a reservoir with such a wall. Method of loading or unloading a vessel in which a cooled liquid product is conveyed over heat-insulated pipes. System for moving a cooled liquid product, comprising a vessel, heat-insulated pipes and a pump for pumping a cooled liquid product through heat-insulated pipes.

EFFECT: method enables to produce a sealed and thermally insulating wall of a storage tank.
