    摘要： A recipient for a gas ultracentrifuge which comprises an oblong cylindrical shell having a lid closing each end, a base flange having an upper end surrounding one end of the shell and a plastically deformable ring interposed between the base flange and the shell. In an embodiment of the invention, the plastically deformable ring comprises a ring-shaped section and a welding shoulder which forms a ring-shaped collar integral with the base flange, the thickness of the shell being greater than that of the ring-shaped collar and about the same thickness as that of the welding shoulder.
