The invention relates to a tubular drill string component for drilling a hole with a drilling fluid flowing around said component (7) and, in the direction from the bottom of the drill hole to the surface, said component including a first end with a female thread, a second end (8) with a male thread, and a substantially tubular central area (9), said component including a communication tube (19) arranged at least in the central area and in contact with a bore of the central area, a signal transmission cable (18) being arranged in the tube, characterised in that the communication tube includes a body made of at least one metal strip arranged with an annular component, the body including, in a cross-section along a plane passing through the axis of the tube, at least two axially elongate sections, with partial mutual overlap with an axial clearance selected to absorb the maximum resilient deformation of the component under an axial compression and/or bending force.

Composant tubulaire de garniture de forage, pour le forage d'un trou avec circulation d'un fluide de forage autour dudit composant (7) et dans un sens allant d'un fond de trou de forage vers la surface, ledit composant comprenant une première extrémité comprenant un filetage femelle, une deuxième extrémité (8) comprenant un filetage mâle, et une zone centrale (9) sensiblement tubulaire, ledit composant comprenant un tube de communication (19) disposé au moins dans la zone centrale et en contact avec un alésage de la zone centrale, un câble de transmission de signaux (18) étant disposé dans le tube, caractérisé par le fait que le tube de communication comprend un corps formé d'au moins un ruban métallique disposé avec une composante annulaire, le corps comprenant, en section selon un plan passant par l'axe du tube, au moins deux tronçons allongés axialement, à recouvrement mutuel partiel avec un jeu axial choisi pour absorber la déformation élastique maximale du composant sous effort de compression axiale et/ou de flexion.
