Abstract: The information about changing the structural state of the metal in the process of long-term operation of heat-resistant steels are given. The dependences of the acoustic characteristics on the size of the local internal stress fields lattice. It shows the relationship between the complex and long-term strength criterion for heat-resistant steels. A fundamentally new methodology for assessing the health and life of metal potentially dangerous equipment TPP, based on identifying patterns of change in the structural-phase state, and internal stress fields in the long-running metal and welded joints spectral acoustic method is presented.

Key words: expertise of industrial safety spectral acoustic method structural-phase condition fields of internal stresses long-term strength welds heat-resistant steel steam pipes
