Abstract

Process for producing a pressure vessel having an enveloping body which occupies an arch shape in its predetermined installation position. The enveloping body has pillow-shaped portions which are connected to one another by stamped transitions at the inner diameter area of the enveloping body. The enveloping body for the intended installation position is placed with its inner diameter area one-sidedly on a die having a raised wedge-shaped profile. A designated outer diameter area of the enveloping body contacts a supporting surface, and the enveloping body is filled with a pressure medium so that the enveloping body is tensioned on the die and, in so doing, is plastically deformed in the area of the wedge-shaped profile.
