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.

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.

Abstract: A process for connecting pipes of different diameters using a single bracket is provided. The pipes at a point at which the connection with the bracket is to take place are deformed such that the cross section of the pipe fits the bracket. The bracket is designed for the pipe with the smallest diameter.

Abstract: A method and a device for making catalyst containers preparing, on a single semi-automatic production line, a station (1), at least a monolith enclosing the monolith with an insulating mat and bonding the insulating mat on the monolith; then slipping and automatically positioning the assembly obtained, in a precut tube, into a mounting and positioning assembly (2); etching the tube in an etching station (3); then transferring it into specific elements (5) for retaining, clamping and driving it in rotation; inserting an insulating cone at stations (5) dispensing and installing insulation cones; heating simultaneously the ends of the precut tube at a heating installation (6) maintaining the temperature at the ends to be deformed; deforming the ends, after a predetermined temperature is reached using a device with deforming rollers (7), while maintaining the forming temperature; extracting and evacuating the resulting container after the floturning and spinning process, towards a continuous cooling device (8), t
