The results are presented on investigation of mechanical-thermal treatment of the tubes as an effective method to increase life and operation reliability of power equipment. General experience of commercial application of the tubes of mechanical-thermal strengthened steel 12Kh1MF on the heating surfaces of supercritical boilers is presented. Possibility and efficiency of application of this method is shown by the example of Trypolie HPP capacities. 11 Ref., 7 Tables, 7 Figures.
Keywords: mechanical-thermal treatment, steel strengthening, equipment life, substructure, high-temperature strength, heat resistance
