AbstractThe problem of the failure of steam generator collectors is actualized and its causes are revealed, one of which is the use of irrational technological processes of fixing heat exchanging pipes to tube sheets. The results of the study of the hydraulic rolling technology influence on the state of press joints are given which allowed to analyze the existing technology and determine reliable criteria to assess the quality of the pipe-tube-board connections.
