摘要:
The present invention relates to a pressure vessel (1) for a high pressure press, wherein the pressure vessel comprising a first sub-cylinder (4), a second sub-cylinder (6), pre-stressing means (8), and a securing member (16). The first and the second sub-cylinders (4, 6) are axially connected to form a cylinder body (2) for enclosing a high pressure medium. The first sub-cylinder (4) is in an outer wall provided with a first seat (22) for receiving a first part (24) of the securing member (16) and the second sub-cylinder (6) is in an outer wall provided with a second seat (26) for receiving a second part (28) of the securing member (16). The securing member (16) is fitted in the first and second seats (22, 26). The securing member (16), and the first and second scats (22, 26) are arranged such that the securing member (16), and the first and second scats (22, 26) cooperate to prevent separating axial movement between the first and the second sub-cylinders (4, 6). The pre-stressing means (8) is provided around the envelope surface of the cylinder body (2) such that the cylinder body (2) is radially pre-stressed and such that the securing member (16) is locked in the first and second seats (22, 26).

An isostatic press is disclosed in which tunnel-like passages are formed between the envelope surface of a force absorbing body and a prestressing device. A method and a press are further disclosed, wherein a cylindrical element is prestressed simultaneously with obtaining a tunnel-like passage on the cylindrical element.

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) arranged for an interconnection is formed at adjacent longitudinal edges (6) of the at least one cylinder segment. The pressure vessel further comprises pre-stressing means (20) provided around an outer envelope surface (4) of the cylinder body for radially pre-stressing the cylinder body and for at least partly decreasing a gap (11) extending along at least a portion of each joint between adjacent longitudinal edges of the at least one cylinder segment.

摘要:
A method of cooling a load provided in a load compartment in a furnace chamber of a furnace of a hot isostatic pressing device includes releasing hot pressure medium from the load compartment. Cool pressure medium is provided for enabling it to fall through the released hot pressure medium outside the load compartment. The thus obtained mixed pressure medium is led into the load compartment. A hot isostatic pressing device includes a load compartment having an aperture near an upper portion thereof configured to vent warm pressure medium into a region surrounding the compartment and a conduit configured to introduce cool pressure medium into the region surrounding the compartment for mixing with the warm medium. The compartment also includes an aperture near a lower portion thereof configured to receive a mix of warm and cool pressure medium from the region surrounding the compartment.
