Abstract

A multipart gas pipe flange for connecting to a counter-flange of an internal combustion engine, having at least one flange plate designed as an outer flange, and having a flange inner part that can be received in said flange plate and is used for attaching a gas pipe which is connected downstream of the inner part in the flow direction and which is fluidically connected. The flange plate has at least one recess for the flange inner part, said recess having at least one inner surface and an inner diameter Di, and a mounting surface which can be placed at least indirectly on the counter-flange. The flange inner part has an outer surface which corresponds to the inner surface and which has an outer diameter Da. The outer surface and the inner surface have a basic shape which tapers in the flow direction, and when being clamped against the counter flange, the outer surface and the inner surface can be clamped relative to each other at least partially in a direction (R) which runs radially in relation to a central axis of the outer surface and/or the inner surface.
