摘要： The present invention relates to an isostatic press for high pressure treatment of a product having a temperature below 0° C., said isostatic press comprising a pressure chamber adapted to contain a first pressure medium, and a container which is placeable in the pressure chamber. The container which is placeable in the isostatic press is adapted to hold the product and a second pressure medium, the container being closable to keep the first pressure medium separated from fluid communication with the second pressure medium. The container is further provided with a pressure transfer device adapted to transfer pressure from the first pressure medium to the second pressure medium, and a body which is made of a material with low adiabatic heat emission relative to adjoining substances, so that the body from adjoining substances absorbs heat, which is generated by adiabatic temperature rise during the high pressure treatment. The invention also relates to a method, a container, and a plant for high pressure treatment of a product having a temperature below 0° C. by means of an isostatic press.

摘要： The invention relates to a forming tool for forming sheet blanks in a diaphragm press of the kind comprising an openable, closed pressure chamber, which is divided in a gas and liquid tight manner by means of a flexible diaphragm. The forming tool is arranged on one side of the diaphragm and a sheet blank to be formed is arranged between the forming tool and the diaphragm. The opposite side of the diaphragm is pressurized by a fluid being supplied at high pressure to cause the flexible diaphragm to deform and, thus, the sheet blank to be pressed against the forming tool. The forming tool comprises an elongate cutting and flanging tool along at least part of its periphery and/or around an intended opening in the sheet blank.

摘要： The present invention relates to a pressure vessel (1) for a high pressure press comprising at least a first sub-cylinder (4) and a second sub-cylinder (6), which are axially connected to form a cylinder body (2) for enclosing a high pressure medium, and a sealing arrangement arranged at the inner wall of the cylinder body for sealing the joint (3) between the first and the second sub-cylinder (4, 6) against leakage of the pressure medium. The sealing arrangement is comprising a ring shaped sealing band (18), a first circumferential protruding flange (30), which is arranged on the inner wall of the first sub-cylinder and which axially extends from the joint (3) and away from the second sub-cylinder (6), and a second circumferential protruding flange (32), which is arranged on the inner wall of the second sub cylinder (6) and which axially extends from the joint (3) and away from the first sub-cylinder (4). The sealing band (18), in mounted position, is located concentrically within the first and the second protruding flanges (30, 32) such that it in a radially pre-stressed manner abuts against the first and second protruding flanges (30, 32) and sealingly overlaps the joint (3) between the first and the second sub-cylinder (4, 6). The sealing arrangement further comprises a first circumferential mounting space (51), which is arranged in the inner wall of the first sub-cylinder (4) and which axially extends from the first protruding flange (30) and away from the second sub-cylinder (6), for facilitating exchange of components of the sealing arrangement.
