Abstract

L'invention concerne un procédé, un dispositif et un appareil pour détecter un défaut de canalisation. Un procédé pour détecter un défaut de canalisation peut détecter avec précision une position et une étendue du défaut de canalisation, et comprend spécifiquement les étapes consistant à : détecter, le long d'une direction longitudinale d'une canalisation, un premier paramètre se rapportant à une densité de flux magnétique ; déterminer si le premier paramètre dépasse un seuil prédéfini ; déterminer une position dans laquelle le premier paramètre dépasse le seuil prédéfini en tant que position du défaut de canalisation ; et déterminer une étendue du défaut de canalisation sur la base d'une valeur du premier paramètre dépassant le seuil prédéfini.
