FIELD: gas equipment.
SUBSTANCE: high-pressure cylinder (variants) and method for producing same (variants). High-pressure (HP) cylinder, namely metallic (HP) cylinder or composite (HP) cylinder, comprising a metallic sheath formed of aluminum alloy, namely of non-heat-treatable aluminum-magnesium alloy. The metallic sheath in a metallic HP cylinder is a metallic cylinder itself, in a composite HP cylinder it is a liner. Method for producing a high-pressure cylinder, including production of a metallic sheath formed of aluminum alloy in the form of non-heat-treatable aluminum-magnesium alloy.
EFFECT: achieved is a production of high-quality high-pressure cylinders.
