The article notes that reducing the risk due to destruction is possible by an a priori
assessment of the maximum technical condition and the degree of degradation of the material of the
technical device. The idea is to use a priori information about the technical condition and degradation
processes that cause a decrease in strength and a decrease in resource. The application of numerical
indicators of corrosion, corrosion resistance of materials, the degree of wear and reserve strength, defects, the risk of destruction and the effectiveness of technical diagnostics at any stage of the life cycle
of a technical device is shown. The justification of the model of transition to the limit state is given.
Numerical indicators of corrosion, corrosion resistance of materials, the degree of wear and reserve
strength, defects, and the risk of destruction are applied. The possibility of developing recommendations for repair, strengthening or replacement of worn-out elements of individual and unique technical
devices of various designs is shown.
