FIELD: machine building.
SUBSTANCE: invention proposes high-pressure vessel (10) having the first end (14) with the first thickening (16) and cylindrical section (30). Vessel (10) includes internal lining (20), composite cover (18) located above internal lining (20) and the first longitudinal ventilation duct (22) located between internal lining (20) and composite cover (18). The first longitudinal ventilation duct (22) includes elongated element (23, 23', 23") forming the ventilation duct and is continued at least from cylindrical section (30) of the vessel to the first thickening (16); besides, the end of the first longitudinal duct is located along the neck of the thickening and opens to atmosphere.
EFFECT: enhanced reliability of a vessel.
