Abstract (en)
[origin: EP0593950A1] A process for fixing a tubular reinforcing insert (12) to a tubular metal structure (10) includes the steps of: forming a hole (30) in the wall of the tubular structure (10) by inward deformation of a portion of the wall so that the deformed wall portion forms a collar (32), force fitting an end portion of the tubular insert (12) into the collar (32), and introducing liquid at high pressure into the tubular structure (10) so as to compress the collar (32) against the end portion (26) of the tubular insert (12). <IMAGE>
