Investigations and practical experience showed that the quality of welded joints of pipelines, meeting the modern requirements largely depends on the quality of treatment of the end faces of groove edges of their butts prior to welding and on the quality of assembly of pipeline parts directly before welding. The paper presents the results of experimental, technological and design works carried out at the Engineering Center for Welding and Control in the Field of Nuclear Energy, on development of a facing tool for metal pipes of 76 to 108 mm diameter. It is shown that, in comparison with the best foreign analogs, the designed facing tool has a number of significant technological and operational advantages. 7 Ref., 2 Tables, 1 Figure.
Keywords: nuclear power engineering, position butt joints of pipelines, machining, pneumatic drive, facing tools, carriages, cutters
