Abstract

Appareil hydrostatique d'essai de tuyaux. Dans une forme de réalisation (figure 1), il comprend deux têtes d'essai 11, 17 ayant chacune une ouverture 21 de réception de tuyau, un élément d'étanchéité 23, un moyen 9 de déplacement axial d'au moins une des têtes d'essai, un moyen 25 d'introduction de fluide d'essai sous pression à l'intérieur du tuyau, un moyen de commande de transducteur 31 produisant un signal de commande représentatif de conditions capables de modifier ou modifiant reellement une position de référence d'au moins un élément d'étanchéité et d'une extrémité correspondante du tuyau lors de l'introduction du fluide d'essai, et un moyen compensateur 45 qui réagit au signal de commande en déclenchant ledit moyen de déplacement,en contrariant ainsi tout déplacement relatif des éléments d'étanchéité et des extrémités du tuyau.
