Abstract

Dans une ligne de tuyaux maritime, des tubes flexibles en vue d'une connexion sont fournis entre des tuyaux maritimes adjacents et agencés par deux. Chaque tuyau flexible comprend une première bride de tube flexible reliée à la bride de fixation d'un tuyau maritime, une seconde bride de tube flexible reliée à la bride de fixation de l'autre tuyau maritime et un corps de tube flexible reliant la première bride de tube flexible à la seconde bride de tube flexible. Dans cette ligne de tuyaux maritime, on peut empêcher effectivement que le corps de tuyau présente des fissures en libérant des tensions à proximité des extrémités du corps de tuyau.
