A method () for pressing at least one article in an arrangement as well as a pressing arrangement (). The method comprises providing an article inside a load compartment and feeding a pressure medium into the pressure vessel and increasing () the pressure in the load compartment; increasing () the temperature and maintaining () the increased temperature and the increased pressure for selected periods of time (t, t); changing () the temperature from the first predetermined temperature level to a second predetermined temperature level (T); feeding () a carbon-containing gas into the pressure vessel; maintaining () the second predetermined temperature level for a selected period of time (t); reducing () the temperature in the load compartment; and discharging () the pressure medium from the pressure vessel and reducing () the pressure in the load compartment.

Method and arrangement for processing articles

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

Pressure vessel for a high pressure press

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.
