Abstract (en)
[origin: EP2446980A2] The pipe (1) has a section (20) joined to another section (10), which comprises a cross-section with an outer contour and an inner contour. The former section comprises another cross-section with an outer contour and an inner contour, and is inserted into the pipe, where a cross-section of the pipe corresponds to the latter cross-section. The two sections are integrally connected together by a double seam (30), and seam layers of the double seam lie directly together, where the pipe is beveled by a chamfer (40) at a free end (7) of the former section. An independent claim is also included for a method for processing pipe ends by plastic cold forming.
