A centraliser (10) for centralising a tubular in a conduit is described. The centraliser comprises a body comprising a upper body portion (12) and a lower body portion (14) and a plurality of arms (16) linking the upper body portion to the lower body portion. Relative movement of the upper and lower body portions towards each other causes the arms to buckle radially outwards into a set configuration in which the arms are engaged, in use, with a conduit.
L'invention concerne un centreur destiné à centrer un corps tubulaire dans un conduit. Le centreur comporte un corps comprenant une partie supérieure de corps, une partie inférieure de corps et une pluralité de bras reliant la partie supérieure de corps à la partie inférieure de corps. Un mouvement relatif de rapprochement des parties supérieure et inférieure de corps provoque une flexion radiale des bras vers l'extérieur, donnant une configuration bloquée dans laquelle les bras interagissent, en cours d'utilisation, avec un conduit.
