Abstract

Procédé pour la fabrication de tubes cintrés qui consiste à produire à partir d'un tube rectiligne plus étroit un tube cintré ayant un diamètre de tube plus grand, et dont les épaisseurs de parois sont uniformes. Le procédé est caractérisé en ce qu'on munit par formage le tube cintré - obtenu à l'aide d'un mandrin de conformation appropriée ou similaire - sur au moins un tronçon d'extrémité d'un prolongement cylindrique de branche, de même diamètre tubulaire, dirigé tangentiellement. Applications pour le formage de tubes cintrés.
