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).
Claims15
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).
The pressure vessel as claimed in 4, wherein the at least one intermediate layer has a hardness which is below the hardness of the at least one cylinder segment.
A high-pressure press for isostatic pressure treatment of articles, comprising a pressure vessel as defined in any one of the preceding claims, including a force-absorbing press frame provided around the force absorbing pressure body.
