Problems of increasing the metal reliability and durability for the TPP thermal power equipment

The paper is devoted to solution of the problem of ensuring the serviceability of the thermal power plant equipment after completion its the design service life. Briefly is described the conception for estimating the power equipment metal state at different stages of the service life completing including the stage of disruption beginning. Possibilities are determined of prolongation of the power unit service life. Modern methods for metal testing and diagnostics are described. Data obtained in the process of metal diagnostics and testing are used for calculation of the residual service life.
