A casing (30) for centrifugal compressors comprises a substantially cylindrical body (31) which is internally hollow and has its own central axis (32). The internal cavity of the casing (30) has an internal central axis (34) substantially coinciding with the axis of rotation of the machine and offset, in a vertical direction, with respect to the central axis (32) of the external surface of the cylindrical body (31) so that the casing (30) has an eccentric shape, having portions of different thickness, so as to create zones where the attachment point for the gas inlet counter-flange (35) and outlet counter-flange (36) can be formed. The invention also relates to a method for the manufacture of a casing (30) for centrifugal compressors. <IMAGE> <IMAGE> |
