Pipe joint, which is formed from the end portions of the pipe sections (1, 2) to be joined together, said end portions having a collar (3, 4), and from flange parts (9, 10) which, as seen from the junction, are placed on different sides of the collars and tightened with applicable fixing means, such as with screws (17) and nuts (18), which collar (3, 4) of the pipe section is formed from the wall of the end of the pipe section by shaping with shaping means (F). The joint surface (7, 8) of the collar (3, 4) of at least one of the pipe sections (1, 2) to be joined is arranged to be divergent by the amount of an angle (a, ß) from the plane perpendicular to the longitudinal axis (L) of the pipe section. The invention also relates to a method and to a flange part arrangement. |
