- Abstract
The results are given on developments of the PWI and its special sub-divisions in creation of domestic specimens of current equipment for preparation to welding of ends and edges of position butts of 14—159 mm diameter pipelines from austenite and pearlite class steels and high alloys in assembly, repair and modernization of power engineering objects, including power generating units of nuclear and heat electric plants, in chemical and power machine building, at enterprises of oil-and-gas complex and other branches of industry. Studied are the peculiarities of design of developed end facers for treatment of 14—76 mm diameter pipes with wall thickness up to 7 mm and pipe cutters for treatment of V- and U-groove edges of position butts in pipes of 76—159 mm diameter and up to 12 mm wall thickness and main constituents of this equipment. It is shown that developed domestic equipment, in comparison with foreign analogues, has a series of significant advantages allowing increasing total efficiency of machining and reducing time of personal staying in zone of influence of harmful environment factors.
