The article deals with the issue of applying prestressed stress in steel prestressed gas and oil pipelines, as well as in shell structures in the case of an increase in internal overpressure to the critical point of rupture of the shell or winding itself, where the expression was also taught that it is possible to calculate the maximum operating pressure of a combined structure, that is, a steel shell and a steel winding, which in the future, when designing such structures, will significantly facilitate the selection of the necessary parameters for more efficient construction of such structures. However, this calculation method can be used by industries that operate vertical cylindrical tanks for oil and petroleum products, research and design institutes
