PRESSURE VESSEL HAVING A VENTILATION DUCT, (VERSIONS) AND A METHOD FOR PRODUCTION THEREOF Russian patent published in 2019 - IPC F17C1/06 

FIELD: storage.

SUBSTANCE: invention relates to the storage of liquefied gases. Vessel under pressure has the first end with the first union, at that the first union has the first external surface. Vessel includes a lining having a second outer surface, a shell provided on the second outer surface, and a first vent channel formed on a portion of the first outer surface and on the nanostructured portion of the second outer surface. Surface structure of the nanostructured portion is sufficiently shallow so that the shell material does not completely penetrate into the nanostructured portion of the second outer surface, and floats on the projections of the nanostructured portion of the second outer surface, thereby leaving a porous ventilation path for gas in depressions of the nanostructured portion of the second outer surface. In compliance with another aspect, vessel (10') under pressure has first end (14a') and second end (14b'), plurality of first longitudinal ventilation channels (22) and plurality of second longitudinal ventilation channels (22). At least one of the first longitudinal ventilation channels (22) is displaced circumferentially around vessel (10') under pressure from at least one of the second longitudinal ventilation channels (22).

EFFECT: higher safety of gas storage.
