A method for the production of a brake pipe conduit (10, 70) having a flange (40, 40a), comprising the following steps: providing a pipe conduit (10, 70) which comprises an inner pipe (20), a coating (30) covering the inner pipe (20), and an end portion (12) terminating in an end face (11); removing the coating from the end portion (12) in such a way that the surface of the end portion (12) causes a first friction coefficient (μ1) in the area of a first coating removal portion (13); removing the coating from the end portion (12) along at least one second coating removal portion (16) in such a way that the surface causes a second friction coefficient (μ2), smaller than the first friction coefficient (μ1), in the area of the second coating removal portion (16); shaping the end portion (12) to form a flange (40, 40a) which has a sealing surface (41, 41a) and a contact surface (42, 42a), such that the first coating removal portion (13) forms the sealing surface (41, 41a) and the second coating removal portion (16) forms the contact surface (42, 42a); the coating (30) being provided with at least one indent (xT) in the area of the first coating removal portion (13) and/or the second coating removal portion (16).
