Abstract (en)
[origin: WO0224369A1] The invention relates to a method and device for forming a one-piece flange (10,18) or rim on the end of a steel (12) pipe. The pipe is placed in a flat position on all sides on the inner surface thereof close to the end thereof and is clamped. One part of the pipe (10) protrudes above the clamped section of the tube (12). The protruding part of the pipe is bent by applying surface pressure against a peripheral section on the inner surface thereof, until a desired outward flectional angle is obtained. The desired flectional angle on all parts of the pipe (10, 18) or a part-section (10) thereof is gradually achieved by rotating the pipe (12) relative to the peripheral section wherein the flection occurs.
