Abstract

L'addition a pour objet un procédé et une installation de fabrication d'une tubulure d'attente sur une paroi de très forte épaisseur. Selon l'addition, constituant une variante du brevet principal, on réalise dans la paroi épaisse un orifice centré sur l'axe de la tubulure à obtenir, puis on chauffe la tôle sur la partie entourant l'orifice à une température comprise entre celle correspondant au point de transformation A3 et celle correspondant à la température de forge, on exerce à l'endroit de l'orifice une traction circulaire monodimensionnelle avec enfoncement, puis l'on déforme l'ensemble obtenu, sans le comprimer, de manière à lui conférer sa forme définitive. L'invention s'applique spécialement à la formation de tubulures sur les viroles constituant une paroi de cuve nucléaire.The subject of the addition is a process and an installation for manufacturing a waiting tube on a very thick wall. According to the addition, constituting a variant of the main patent, an orifice centered on the axis of the pipe to be obtained is produced in the thick wall, then the sheet is heated on the part surrounding the orifice to a temperature between that corresponding at the transformation point A3 and that corresponding to the forging temperature, a one-dimensional circular traction with depression is exerted at the location of the orifice, then the assembly obtained is deformed, without compressing it, so as to give it its final form. The invention applies especially to the formation of tubes on the ferrules constituting a nuclear vessel wall.
