FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in such industries as shipbuilding and chemical machine building when it is necessary to use vessels of increased rigidity and strength along with minimal weight of the structure. The effect is reached by the fact that a vessel is made from a multilayer cylindrical shell consisting of the inner, second, middle, third and outer separate cylindrical shells. Each of the separate shells comprised in the multilayer cylindrical and in two multilayer hemispherical shells is made from two identical parts.
EFFECT: production of vessels of increased rigidity and strength along with minimal weight of the structure.
