FIELD: machine building.
SUBSTANCE: vessel consists of metallic liner with one mouth in bottom and of external power shell out of composite material. The shell is formed with combination of groups of layers of high-module fibres of reinforcing material oriented in spiral and circumferential directions at specified density of folding. Also on a cylinder part of the vessel in the power shell there is made a local belt of predicted destruction in form of a part of the shell limited inside with cylinder surface of the liner and outside with surface of linear one-pole hyperboloid of revolution formed with spiral oriented fibres of reinforcing material.
EFFECT: upgraded durability and reliability of vessel.
