Title (EN) CORROSION AND CRACK DETECTION FOR FASTENER NUTS
(FR) DÉTECTION DE CORROSION ET DE FISSURES POUR ÉCROUS DE FIXATION
Abstract:
(EN) Methods and devices are provided for detecting, corrosion and cracks in fastener nuts. In an exemplary embodiment, an apparatus can be configured to couple to a fastener nut to facilitate inspection of the fastener nut for detection of flaws in the fastener nut, such as corrosion and cracks. The apparatus can be configured to couple to the fastener nut when the fastener nut is mounted on a fastener and in use in a larger system such as a subsea drilling apparatus or other system in which fasteners with fastener nuts attached thereto are used. The apparatus can include an ultrasonic probe configured to facilitate inspection of the fastener nut using ultrasonic waves.
(FR) La présente invention concerne des procédés et des dispositifs de détection de corrosion et de fissures dans des écrous de fixation. Dans un mode de réalisation exemplaire, un appareil peut être configuré pour être couplé à un écrou de fixation pour faciliter l’inspection de l’écrou de fixation pour la détection de défauts dans l’écrou de fixation, tels que la corrosion et les fissures. L’appareil peut être configuré pour être couplé à l’écrou de fixation lorsque l’écrou de fixation est monté sur un élément de fixation et, en utilisation dans un système de grande taille tel qu’un appareil de forage sous-marin ou un autre système dans lequel des éléments de fixation avec des écrous de fixation fixés à ceux-ci sont utilisés. L’appareil peut comprendre une sonde ultrasonore configurée pour faciliter l’inspection de l’écrou de fixation au moyen d’ondes ultrasonores.
