FIELD: storage, transportation and use of compressed gases. SUBSTANCE: bottle is welded from titanium alloy. Maximum curvature radii of outer surfaces of bottom ($$$) and neck ($$$) and thickness of bottom ($$$) and neck ($$$) are related to radius of outer surface of cylinder ($$$) and its thickness ($$$) as follows: $$$ = 1 - 1.5; $$$ = 1 - 1.5; $$$ = 0.45 - 0.75; $$$ = 0.45 - 0.75. EFFECT: enhanced durability and reliability. 1 dwg øøø1 |
