Abstract
The ratio σ 20u /σ 550u can be considered a recommended parameter determining the degree of loss of strength of the metal and exhaustion of the heat-resistance resource of steam pipelines of thermal power plants. We have established that, in steam pipelines with increased residual strain and unsatisfactory structure of the metal, the greater the degree of its loss of strength in the course of operation, the higher is this ratio.
