Abstract

Procédé pour le traitement de la matière constitutive d'un tube métallique recuit enroulé, par exemple sur un dévidoir, sous la forme d'une couronne à limite d'écoulement prononcée et destiné à être mis en oeuvre ultérieurement en tant que tube droit après avoir été étendu dans un plan. Avant d'être étendu, le tube métallique est tiré à travers une ouverture d'outil se rétrécissant dans le sens d'étirage de façon à être soumis à une transformation par traction et compression consistant en une déformation à froid à l'état creux qui a pour effet de réduire le diamètre extérieur du tube d'une quantité allant jusqu'à 4 %. L'invention est applicable notamment à des tubes en acier à section circulaire d'un diamètre extérieur de 40 mm au maximum.
