(FR) APPAREIL, PROCÉDÉS ET SYSTÈMES DE DISTINCTION DE DÉFAUT
Abstract
(EN)
In some embodiments, an apparatus and a system, as well as methods, may operate to include acquiring eddy current data from at least two concentric pipes. Further activity may include determining spatial frequency content of the eddy current data, and determining locations of defects in each of the pipes based on the spatial frequency content. Additional methods, apparatus, and systems are disclosed.
(FR)
Certains modes de réalisation concernent un appareil, un système et des procédés pouvant fonctionner pour acquérir des données de courant de Foucault à partir d'au moins deux tuyaux concentriques. Une autre activité peut consister à déterminer un contenu de fréquence spatiale des données de courant de Foucault, et déterminer des emplacements de défauts dans chacun des tuyaux sur la base du contenu de fréquence spatiale. L'invention concerne également des procédés, un appareil et des systèmes supplémentaires.
