Embodiment Construction

[0046] The invention is mainly described with reference to a few examples. However, a person skilled in the art will readily appreciate that other embodiments than those disclosed are equally possible within the scope of the invention as defined by the appended claims.

[0047] refer to figure 1 , schematically shows an illustration of a cylindrical body 1 according to an embodiment of the present invention. The cylinder main body 1 includes five cylinder segments 2, each of which has the shape of a substantially rectangular flat plate. The length of the cylinder section 2 is parallel to the cylinder axis C A extension, where the length of the cylinder segment 2 defines C L is the length of cylinder body 1. The width of the cylinder section 2 is along the circumferential direction C D Slightly arched, so that the cylinder segment 2 is arranged for D connected to each other to form a cylindrical body 1 .

[0048] Although in figure 1 The cylinder body 1 described in inc...

Abstract

A pressure vessel comprising a pressure chamber (5) arranged for accommodating a pressure medium, comprising at least one cylinder segment (2) arranged for longitudinal connection to form a cylinder body (1), whereby a joint (7) is formed at adjacent edges (6) of the at least one cylinder segment for sealing the adjacent edges, and first pre-stressing means (20) arranged for exerting radial compressive forces on the at least one cylinder segment for attaining tangential compressive stress (16) at the joint(s).

Description

technical field [0001] The present invention relates to the field of high pressure extrusion, and in particular, pressure vessels for isostatic extrusion. Background technique [0002] High-pressure presses are often used for sealing powder or cast materials to achieve the elimination of material porosity, for example for turbine blades in aircraft. Thus, pressure is applied to the object placed in the press in order to substantially increase the useful life and strength of the object, and more specifically, increase the fatigue strength. Another area of ​​application is the manufacture of products that need to be sufficiently dense and have a non-porous surface. [0003] The objects subjected to the high-pressure extrusion process are positioned in the loading compartment of the pressure chamber. After filling, the pressure chamber is sealed and a liquid or gaseous pressure medium is introduced into the pressure chamber and the filling compartment of the pressure chamber....
