Abstract

FIELD: nuclear and chemical engineering; bimetallic inserts for welding stainless steel pipes with zirconium alloy pipes. SUBSTANCE: adapter is made in the form of overlapped diffusion-welded bushings of metals corresponding to metals of pipes to be welded. Female bushing of adapter is made of stainless steel. Mated surfaces of bushings over entire length of overlapping are provided with alternating projections and recesses, with projections getting into recesses. Overlapped diffusion-welded joint is made with hard diffusion lining of thickness not exceeding 5 μm. EFFECT: enlarged operating capabilities. 7 cl, 4 dwg

Использование: в ядерной технике и химическом машиностроении как биметаллическая вставка при сварке труб из нержавеющих сталей с трубами из циркониевых сплавов. Сущность изобретения: переходник для сварки труб из нержавеющих сталей с трубами из циркониевых сплавов, выполненный в виде нахлесточного диффузионного сварного соединения втулок из металлов, соответствующих металлам свариваемых труб. Охватывающая втулка переходника выполнена из нержавеющей стали, а сопряженные поверхности втулок на всей длине нахлестки имеют чередующиеся между собой выступы и впадины, входящие друг в друга. Нахлесточное диффузионное сварное соединение выполнено с твердой диффузионной прослойкой толщиной не более 5 мкм.Usage: in nuclear engineering and chemical engineering as a bimetallic insert for welding pipes of stainless steel with pipes of zirconium alloys. The inventive adapter for welding pipes of stainless steel with pipes of zirconium alloys, made in the form of lap diffusion welded joints of metal sleeves corresponding to the metals of the welded pipes. The adapter sleeve is made of stainless steel, and the mating surfaces of the sleeves have alternating protrusions and depressions that enter into each other along the entire length of the lap. Lapped diffusion welded joint is made with a solid diffusion layer with a thickness of not more than 5 μm.
