The invention relates to a method for the manufacture of a flanged member (1) for use in a pipe system, as well as a flanged member manufactured according to the method. The flanged member comprises a radially projecting flange (3), forming flange part (2), and comprises also a pipe part (4), said flange part having a front end surface (7) intended for assembly with another element forming a part of the pipe system, and a rear end surface (6) facing said pipe part. The rear end surface of the flange part is essentially plane in the radial direction and delimits the rear end of the flange part (2), against the pipe part (4), together with an extension (9) of the rear end surface (6) inwards, in the radial direction. The pipe apart has a free end (5), adapted to be assembled with the pipe system. Further, said flange part has a mass Mf and said pipe part has a mass Mp. According to the method, the pipe part (4), before the final machining of the front end surface (7) of the flange part (2), is made to such a length (a) in the axial direction, that its mass Mp is at least 35% of the mass Mf of the flange part.
