An apparatus for isolating and/or testing a section of a pipe includes a generally annular body having, on each end, a boss. A resilient member such as an O-ring is provided between the annular body and each boss. A series of electromagnets are provided for forcing or urging the bosses towards each other thereby resulting in deformation of the resilient members resulting in a seal being formed between the apparatus and the pipe. A method for isolating and/or testing a pipe segment is also provided.
L'invention concerne un appareil permettant d'isoler et/ou de tester une section d'un tuyau et comprenant un corps de forme générale annulaire présentant, sur chaque extrémité, une bosse. Un élément élastique, tel qu'un joint torique, est placé entre le corps annulaire et chaque bosse. Une série d'électroaimants est placée de manière à forcer ou contraindre les bosses les unes vers les autres, une déformation des éléments élastiques étant ainsi obtenue et un joint étant ainsi formé entre l'appareil et le tuyau. L'invention concerne également un procédé permettant d'isoler et/ou tester un segment de tuyau.
