Abstract

L'invention concerne un tube flexible ultra fin constitué d'un alliage comprenant (en % en poids) : 17 à 23 % de Cr, 0,1 à 0,35 % de Ti, 0,4 à 8,5 % de Cu, 0,2 à 2,4 % de Mo, 0,01 à 0,06 % de Co, 0,3 à 2,0 de Ni, 0,2 à 1,0 % de Nb, 0,05 à 0,4 % de V, 0,001 à 0,020 % de B, moins de 1,0 % de Si, moins de 1,0 % de Mn, moins de 0,020 % de C, moins de 0,020 % de N, moins de 0,035 % de P, moins de 0,025 % de S, moins de 0,005 % de Mg, moins de 0,006 % d'O, moins de 0,08 % d'Al, et la part résiduelle de Fe et d'inévitables impuretés. Le procédé de fabrication du tube comprend les étapes consistant à : laminer à froid une tôle, effectuer une trempe et un revenu, aplanir, réaliser un processus d'argenture, préparer une bobine, nettoyer, positionner, enrouler et former, souder, maintenir chaud, détecter les défauts et marquer, procéder à une rectification cylindrique et déterminer le diamètre, et bobiner. Le tube a une épaisseur de 0,04 à 0,2 mm, présente une résistance à la corrosion au chlore supérieure à 100 ppm, valeur plus de 0,5 fois supérieure à celle de la résistance à la corrosion du Cu, une résistance mécanique environ une fois supérieure à celle du Cu, une ductilité similaire à celle du Cu, et une énergie thermique supérieure à celle de tubes en Cu classiques. Le tube peut être utilisé comme tube de rayonnement à haute efficacité dans différents conditionneurs d'air ou appareils réfrigérants.
