Abstract

L'invention concerne un tuyau en acier à haute formabilité, dont la valeur r dans le sens longitudinal est supérieure ou égale à 1,2 et de préférence supérieure ou égale à 1,6 sur toute la partie comportant une zone de raccord. L'invention concerne également un procédé de fabrication correspondant, qui consiste à chauffer un tuyau de cercles d'acier assemblés par soudure électrique, à une température Ac1 ou supérieure, et à soumettre le tuyau échauffé à une opération d'étirage-réduction, selon une réduction de diamètre supérieure ou égale à 30 %, à 600 DEG C ou plus et jusqu'à une température Ac1, puis éventuellement à chauffer de nouveau le tuyau durant ou après le refroidissement qui suit l'opération susmentionnée, à une température comprise entre 600 DEG C et 900 DEG C, en maintenant la température pendant une seconde au moins. Ce type de tuyau à haute formabilité présente une partie fondue ou transformée en soudure par joints, avec une valeur r élevée dans le sens axial, équivalant à la valeur r d'une partie non soumise à la soudure, et la formabilité est particulièrement remarquable à la courbure.
