An assembly with flanges is provided. The flanges are used for welding onto a pipe end of a pipe for a pressure-bearing flange connection of two pipe ends, wherein the flange extends in a circumferential direction about a central axis of the pipe and has a first end face in the axial direction of the pipe end, wherein the first end face has a sealing groove extending in the circumferential direction, which sealing groove divides the end face into a radially inner inside surface and a radially outer outside surface. In order to avoid rework, the inside surface is axially recessed by a recess on average relative to the outside surface. An adaptation ring or an assembly having a flange or adaptation ring is also provided. |
