Abstract

L'invention concerne un procédé pour la fabrication d'un tuyau en acier, dans lequel une feuille en acier, dont les bords ont été incurvés, est soumise à un pliage à trois points une pluralité de fois dans une direction de la largeur de façon à former ladite feuille en acier sous la forme d'un cylindre, et après que des parties de mise en butée soient soudées ensemble de façon à produire une ébauche de tuyau (1), un évaseur comporte une pluralité d'éléments de matériel servant à évaser (2) insérés dans l'ébauche de tuyau et l'ébauche de tuyau est évasée. Par le fait d'évaser l'ébauche de tuyau avec le matériel servant à évaser (2), placé au-dessus de chacune des sections (9) de l'ébauche de tuyau qui n'a pas été déformée par le pliage à trois points, des tuyaux en acier avec une excellente précision dimensionnelle peuvent être fabriqués avec un haut rendement. Si l'on considère que N représente le nombre d'éléments de matériel servant à évaser, le pliage à trois points est réalisé de préférence aN-1 fois (a étant un entier, par exemple 1, 2, etc.).
