HIGH PRESSURE CASING FROM COMPOSITE MATERIALS Russian patent published in 2015 - IPC F16J12/00 F17C1/16 B21D51/24 

FIELD: machine building.

SUBSTANCE: invention relates to HP casings from composite materials used, in particular, in propulsion plants, and can be also used in all structures of the machine building and chemical industries, where casings for gaseous and liquid mediums are used. HP casing from the composite materials contains pressure shell 1 with cylindrical part 2, with convex heads 3 and 4, with flanges 5 and 6, located in the pole holes of the heads 3 and 4, lined from inside with the protecting coating 7, and with the frame-strakes 8 and 9 located on it on collapsible streaks 10, additional local layers 11 on the cylindrical part of the pressure shell.

EFFECT: invention increases carrying capacity of the connection between the pressure shell and frame-strake under action of the axial forces together with the internal pressure with extension of the application area.
