Abstract

A formed pipe end-section of a pipeline for connecting the pipeline at an end includes: an annular bead with a first abutment face facing away from the end of the pipeline and a second abutment face facing towards the end of the pipeline; a chamfer reducing a diameter of the pipe end-section from the annular bead towards the end of the pipeline; and a radial recess for accommodating a sealing ring. The chamfer extends at least between the annular bead and the radial recess.
