Abstract

Procédé de traitement thermique de tubes métalliques, notamment d'acier dans lequel on empile les tubes dans un four. On réalise une ou plusieurs bottes de tubes régulièrement empilés et maintenus contre tout jeu latéral en étant rectilignes, de préférence sous forme de bottes hexagonales. L'invention est applicable notamment aux tubes minces et très longs.
