Pipe-flange joint, especially for vehicle combustion engine gas line, has radial peripheral pipe fold on which flange fitting rests to form lip acting as connecting point for peripheral lip weld joining parts in gas-tight manner

摘要

The joint consists of a solid flange, especially a sintered flange (1), and a thin-walled steel pipe (2) for the medium with a radially outwardly facing peripheral pipe fold (4) on which a flange recess (3) rests to form a lip (5) with the fold that acts as a connecting point for a peripheral lip weld (6) with which the two parts are joined in a gas-tight manner.
