Notes:
The number of potentially dangerous equipment that has completed its establishedoperational time, but is still being used, is permanently increasing. Therefore there is a problem ofits further operations. A decision to continue to operate power-generating plants, when the initialresource of the equipment’s working time is ended, and its further operation without considerableexpenditures on repair and the diagnostic of a metal state is possible only with the help of long-termresearch of metal in power-generating plants. Only a complex of research techniques can estimatethe real state of a construction. In the article problems connected with the definition of operationreliability of steam pipeline elbows are investigated. Different areas of an elbow were researched.Results of a microstructure analysis, and mechanical characteristics (time history) research of anelbow metal are presented. Also results of calculation of an elbow on low - cyclic thermal fatigueare presented
