So far, certain approaches have been developed to extension of service life of equipment in the different stages of metal physical exhaustion. The possibility of defining operating conditions of plant equipment beyond the fleet service life becomes even more relevant with increased operating time. The service life is determined as an individual one and is assigned based on the results of individual an inspection of a separate element or the largest group of single-type equipment elements of the considered plant. The fleet service life being reached is followed by diagnostics of specific units of power installations and analysis of their operation, measurement of actual dimensions of components, examination of structure, properties and damage accumulation in the metal, non-destructive testing and estimate of stress strain state and residual service life of the component. The results of performed studies are used to determine an individual service life of each element of energy equipment.
