Abstract

La présente invention concerne un procédé de production d'un tube en acier composite spiralé comprenant les étapes suivantes: (1) sélection d'une bobine de feuillard en fonction du diamètre du tube composite (S1), (2) déroulage (S2), (3) planage (S3), (4) meulage des bordures (S4), (5) roulage en tube (S5), (6) soudage intérieur et extérieur (S6), (7) recherche de fissures (S7), (8) coupe à la longueur déterminée (S8), (9) chanfreinage d'extrémité en tête plate (S9), (10) rangement en entrepôt (S10). Pour l'étape (1), on utilise du feuillard composite bimétallique acier inoxydable et acier au carbone. Pour l'étape (6), on utilise de la baguette de soudure sans étain. Ce procédé qui est facile à mettre en œuvre convient à une machine de fabrication de tube spiralé conventionnel conçue pour la production de tube de métal composite.
