Abstract

Véhicule d'inspection de pipelines pour la détection des défauts de parois desdits pipelines. Il comprend un dispositif de support qui comprend un élément annulaire portant des frotteurs 7 sur chacun desquels un module 5 de détection est monté. Chaque frotteur comprend deux plaques articulées entre elles et repoussées élastiquement vers l'extérieur par un ressort plat, de manière à suivre le profil de la surface intérieure de paroi du pipeline. Domaine d'application : vérification de pipelines.
