HIGH PRESSURE BOTTLE Russian patent published in 2019 - IPC F17C1/06 F16J12/00 

FIELD: storage.

SUBSTANCE: invention relates to storage of compressed gases. High-pressure bottle contains a power shell from a composite material, an internal composite polymeric liner consisting of two half-liners attached at ends, and metal embedded elements in the bottoms. End parts of half-liners are made with thickenings relative to external surfaces by value not less than t=(α₁-α₂)⋅D/2⋅ΔT, where α₁ and α₂ – respectively coefficients of thermal expansion of material of liner and composite material of power shell, D – outer diameter of liner in place of thickening, ΔT is temperature difference in bottle operating conditions. Mating surfaces of thickenings with walls of half-liners are conical with taper angles of 15–30°. On thinning walls of half-liners annular reels of composite material with thickness of not more than t=(α₁-α₂)⋅D/2⋅ΔT.

EFFECT: higher reliability of the bottle.
