摘要 |
The invention concerns a tubular component (2) for the exploration or operation of a hydrocarbon well, comprising a pipe body (24) with an axis of revolution (20) extended at at least one of its ends (25) by a first tool joint (23) provided with a threaded end that can connect the tubular component (2) to another tubular component by makeup, the first tool joint (23) being friction welded to said end (25) of the pipe body (24) in order to define a first weld zone (21), characterized in that the circumferential surface of the tubular component comprises an annular groove (22) extending in the region of the first weld zone. |
