A flexible pipe element is provided formed as a metal bellows with at least one corrugated bellows section and a bellows brim, which forms one end of the metal bellows, and a connection element for connecting the metal bellows to a continuing pipe part or to a connector, with the connection element having a connection area for abutting a contact area of the bellows brim. An annular bulge is formed in the contact area of the bellows brim and/or in the connection area of the connection element projecting beyond an average level of the contact area and/or an average level of the connection area in order to form a linear seal between the contact area and the connection area. A method for producing such a flexible line part is also provided.
A flexible pipe element, comprising a metal bellows (1) with at least one corrugated bellows section (2) and a bellows brim (3), which forms one end of the metal bellows (1), a connection element (4) for connecting the metal bellows (1) to a continuing pipe part or to a connector, the connection element (4) comprising a connection area (5) for abutting a contact area (6) of the bellows brim (3), an annular bulge (7) formed in the contact area (6) of the bellows brim (3) or in the connection area (5) of the connection element (4) projecting beyond an average level of the contact area (6) or an average level of the connection area (5), or in both the contact area and the connection area, in order to form a linear seal between the contact area (6) and the connection area (5).
