Abstract

The present invention relates to metal technology and to manufacture of large metal pieces, and in particular to manufacture of large metallic sleeve pieces, the large metallic sleeve pieces being suitable for various flow applications, such as those in marine technology and process technology, and to manufacturing methods of these large metallic sleeve pieces. The large, metallic sleeve piece of the invention comprises a sleeve structure (13), (15) made of metal plate, the inner surface of the sleeve structure being formed by means of forming rolls (7 to 12) such that the metallic sleeve piece has assumed its inwardly convex shape.
