    Abstract: A flange plate for a manifold of an exhaust-gas system for internal combustion engines, which flange plate can be fixed via at least one holding device to an exhaust-gas outlet connecting piece of the internal combustion engine by a first outer layer, formed as a mounting layer, which can be placed at least partially directly or indirectly against the exhaust-gas outlet connecting piece via a seal, and the flange plate can be applied to the holding device by a second outer layer, formed as a holding layer, in order to generate a holding force F, acting at a right angle to the mounting layer, for sealingly placing the mounting layer against the exhaust-gas outlet connecting piece, and the flange plate having at least a first intermediate layer which is arranged, relative to the holding force F, between the mounting layer and the holding layer. Here, the first intermediate layer is formed as a cavity structure, wherein the cavity structure has single- or multiple-part wall parts which extend in a direction parallel to the mounting layer and are arranged adjacent to one another, the wall parts having a width b1, measured in a direction parallel to the mounting layer, and having a height h1, measured in a direction at a right angle to the mounting layer, where h1>b1, wherein the different wall parts delimit a plurality of cavities which are open towards the mounting layer or towards the holding layer or, together with the mounting layer and the holding layer, delimit an open-ended channel.

    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.
