Zusammenfassung:	An equipment is described to be moved through the inside of ducts (pig), carrying on-board instruments which basically comprise an electronics module (3), a battery module (4), MMM magnetic sensors (6) and an odometrical system (7, 8), and which are intended for detecting and measuring structural anomalies and stress concentration zones in rigid or flexible ducts made of a metallic material and located on land or in the depths of the sea (offshore) by non-destructive metal magnetic memory (MMM) testing. L'invention concerne un équipement conçu pour se déplacer à l'intérieur de conduits (Pig) qui comprend des instruments comportant, à la base, un module électronique (3), un module de batterie (4), des capteurs (6) magnétiques MMM et un système odométrique (7, 8), lesquels sont destinés à détecter et mesurer des anomalies structurales et des zones de concentration de tension dans des conduits en matériau métallique qui sont rigides, flexibles, sous terre et dans les profondeurs de la mer (" offshore ") au moyen d'un test non destructif de la mémoire magnétique en métal (MMM). É descrito um equipamento para se deslocar pelo interior de dutos (Pig) que embarca uma instrumentação, que basicamente compreende: um módulo de eletrónica (3), um módulo de bateria (4), sensores (6) magnéticos MMM e um sistema odométrico (7,8) a qual é destinada a detectar e mensurar anomalias estruturais e zonas de concentração de tensão em dutos de material metálico, sejam rígidos, sejam flexíveis, em terra e em profundezas do mar (" offshore ") por intermédio de ensaio não destrutivo de Memória Magnética de Metal (MMM).
