Abstract

L'invention concerne un détecteur de corrosion, adaptable à des pipelines étagés, qui comprend : un cadre de détecteur (1), une structure de tige de liaison de ressort, une structure de support de ressort de torsion et une structure de sonde d'aimant pouvant s'adapter aux pipelines étagés. La structure de sonde d'aimant comporte : un boîtier en forme de rainure (8) qui est rempli d'un noyau en fer (12) ; un mécanisme de brosse en acier d'aimant, disposé au niveau de l'extrémité avant et de l'extrémité arrière du noyau en fer (12), respectivement, et qui est composé d'un aimant (9) et d'une brosse en acier (10), le mécanisme de brosse en acier d'aimant étant en contact avec la paroi de tuyau des pipelines étagés pour éliminer la saleté de la paroi de tuyau des pipelines étagés ; un mécanisme de sonde collectrice (11), disposé au niveau d'une extrémité intermédiaire du noyau (12), et un mécanisme de roues anti-collision (7) disposé sur la paroi externe du boîtier de type rainure (8) pour empêcher la structure de sonde d'aimant de se cogner dans les pipelines étagés.
