[origin: EP0084485B1] 1. Nodal point for the construction of metallic tubes, especially for drilling platforms, characterized in that it comprises, in the tubular element portion (10) on which are welded the tubes (12) constituent of the point of junction, at least one steel stiffening element, comprising a cylindrical main portion (16) coaxial with said tubular element and provided with annular ribs (18), said stiffening element being ferruled inside the tubular element (10) with a ferruling rate sufficient for preventing it from being disunited from the tubular element.
