Abstract

Un appareil de centrage d'un tubage comprend un centreur (10), par exemple, un centreur à arceaux présentant une pluralité d'arceaux à ressort (24) reliant des colliers (20) à extrémités espacées. Un collier d'arrêt (12) est fixé sur le tubage (2). Ledit collier d'arrêt (12) est agencé sur le tubage (2) entre les deux colliers terminaux (20) du centreur (10), dans les arceaux à ressort (24), de sorte que ledit collier d'arrêt (12) rentre sélectivement en contact avec un des colliers terminaux (20) et retient le centreur sur le tubage. Le collier d'arrêt (12) est agencé pour être collé au tubage (12) et pour plus de sécurité, il serre la liaison adhésive.
