The objective of this work is to develop the basic theory of elaboration principles for the optimized construction of multielement containers. For this purpose, two constructions were studied: the container formed by any number of sleeves and the thin-walled sleeve wrapped with a pre-tensioned steel ribbon. The optimized structure of a multi-element container requires the correlation const i K i = ⋅σ 2 to be maintained, where: Ki = coefficient of thickness of the thick wall; σi = allowable

... s on the internal diameter of sleeve "i". The dependence obtained between the dimensions of the container, the number of elements, and its mechanical properties delimit construction. The study found that winding steel ribbon around the core, steel sleeve, doubles the capacity limits of the container. The developed work allows basic questions arising during the design of the new compound containers to be solved.
