ABSTRACT:
A hot-isostatic press comprising a load-carrying member (1) adapted to be supported by a substantially annular support member. The annular support member is arranged on an underlying support (4) and encloses a heat insulation (10). Further, at least part of the annular support member is arranged in the form of a number of axial segments (3), which are arranged side-by-side and are connected at the top and bottom to adjacent members by means of an attachment which guides the segment in a hinge-like movement relative to adjacent members to take up the radial movements which arise in the segment as a result of the temperature gradient between the upper and lower parts of said support member. The height of the heat insulation corresponds at most to the beginning of the axial segments. (FIG. 1 )
