Abstract

A casing for isostatically pressed pieces, which are intended for the extrusion of metal articles, in particular stainless steel metal pipes. The outer and inner envelopes (302, 304) of the casing (301) are comprised of a thin metal sheet: the outer envelope (302) at least has, along the periphery thereof, resistance characteristic substantially uniform in the axial direction and it consists of, in particular, a spiral welded pipe and is provided, preferably, with a bulge directed outwardly, opposed to the narrowing. It is provided, at least at the front part of the casing an intermediary piece which is made of one or several parts; this piece is obtained from ductile material or from a material obtained by compression of a powder. It is also provided a method for producing such casings and pressed pieces and a method for the extrusion of pipes as well as pipes obtained by such method.
