Abstract

The results of analyzing the experience from the recovery heat treatment (RHT) of the casing parts (HPCs, stop valves) of PT-60-12.8 and T-100-12.8 turbines, which was performed under factory conditions, is presented. It is demonstrated that the application of technology comprising two-stage normalization followed by high tempering is an effective technique for maintaining the operational efficiency of casing parts.
