Abstract

La présente invention concerne un tuyau métallique présentant un tube de protection interne et son procédé de fabrication, dans lequel le tube de protection interne capable d'améliorer la résistance à la corrosion et la résistance à l'usure est inséré dans le tuyau métallique pour augmenter la durée de vie du tuyau métallique et empêcher un matériau traversant le tuyau métallique d'être contaminé en raison de la corrosion. Le procédé selon la présente invention permettant de fabriquer le tuyau métallique présentant le tube de protection interne comprenant : une étape consistant à insérer le tube de protection interne dans un corps principal de tuyau, le tube de protection interne présentant un diamètre externe inférieur au diamètre interne du corps principal de tuyau ; une étape consistant à insérer une unité d'expansion de tube dans le tube de protection interne ; une étape d'expansion de tube consistant à étendre le tube de protection interne vers l'extérieur via l'unité d'expansion de tube, qui a été insérée dans le tube de protection interne, pour permettre à la surface circonférentielle externe du tube de protection interne d'entrer en contact avec la surface circonférentielle interne du corps principal de tuyau, de sorte que le tube de protection interne et le corps principal de tuyau sont accouplés l'un à l'autre ; et une étape de chauffage de tuyau consistant à chauffer une partie du corps principal de tuyau où le tube de protection interne doit être déployé, afin d'augmenter le diamètre interne du corps principal de tuyau par une valeur prédéterminée une fois le tube de protection interne inséré dans le corps principal de tuyau.
