The state and key directions of development of technologies for restorative heat treatment of steam pipeline welded joints are considered. The technologies of heat treatment and their advantages and disadvantages are presented. The first part of the review presents a summary of the development of restorative heat treatment. The directions of development of restorative heat treatment of welded joints, the most promising for extension of service life of steam pipelines according to the opinion of the authors, were formulated and justified. The justification of the possibility of using heat treatment of long-operating elements of steam pipelines with a degraded structure and presence of damages is given. The possibility of producing a metal of a steam pipeline with a structural state and properties, meeting the service requirements is justified. 23 Ref., 3 Figures.
