Abstract The main features of the performed technical diagnostics of damaged petrochemical equipment are considered for evaluation of its reparability. It is noted that in order to detect defects, the nature of their development, and the subsequent possibility of performing repair and restoration works, an individual approach to selection of control means and methods is required in most cases. The work gives an example of development and implementation of repair and welding technologies for restoration of integrity and service characteristics of vessel bodies taking into account the results of technical diagnostics and investigation of mechanical properties. 7 Ref., 3 Tables, 7 Figures.
Keywords: repair of regenerator casing, visual and ultrasonic testing, welded joints, cracks, repair-welding technology
