FIELD: mechanical engineering.
SUBSTANCE: method comprises making inner sealing shell, outer load-bearing shell by winding the reinforcing threads on the inner shell and polymerizing the shell. Before making the inner sealing spherical shell, the connecting pipes are set in the mold for rotating molding, the grooves are made in the outer and inner surfaces, and ring projection is made on the inner surface from the side of the outlet opening of the connecting pipes. The inner sealing shell is then mounted for permitting rotation. The thread is wound on the shell by means of rotation of the shell, and before winding next layer each layer the angle between the axis of rotation of the shell and axis of rotation of the device for applying the thread changes by at least 2 degrees. The number of turns and thickness of next layer exceed these for the previous layer. The reinforcing threads are impregnated with a binder in vacuum. The binder is polymerized at a temperature lower than the temperature of softening of the material of the inner shell.
EFFECT: simplified method and enhanced strength of vessel.
