<p>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.</p> |
