Cette invention a trait à un procédé de fabrication, dans un atelier sur le site d'utilisation, de tuyau sensiblement cylindrique à utiliser dans un trou ou dans un conduit. On utilise, dans le cadre de ce procédé, un demi-produit métallique plat enroulé autour d'un touret. Une fois le demi-produit déroulé, on le travaille pour former un tuyau sensiblement rond dont le joint refermé et lié court parallèlement à l'axe dudit tuyau.
