A decision to continue to operate power-generating plants, when the initial resource of equipment working time is ended, and its further operation without considerable expenditures on repair and diagnostic of a metal state is possible only with the help of long-term research of metal of power-generating plants. Only a complex of research techniques can estimate a real state of a construction. The article deals with the analysis of mechanical characteristics, residual strains, structure of a steel, change dynamics (time history). The results of experiments and inspection a state of a steam line steel allow to forecast further material behaviour and to make conclusions about possibility of further operation of the equipment.
