Pressure vessel or pressure line with a flange connection of increased pressure load

摘要

a pressure vessel or a pressure line (1),comprising a first half of the housing (2a) with a first flange section forming on it (4a) and a second half of the housing (2b) with a second flange section forming on ithnitt (4b), which by welding in the area of the adjacent sealing surfaces (6a, 6b) of the first and second flange sections (4a,4b) are connected to each other in a liquid or gas -dense way by the fact that the adjacent sealing surfaces (6a,6b) are positioned at an angle (a) greater than normal (N) at the inner wall of the pressure vessel in the area of the connector.
