PIPES ET TUBES - SANS COUTURE
Une billette de chauffage est mise en contact avec les roulements de rotation coniques de telle manière qu'affiché soit tiré dans l'espace permis entre les roulements. Le mandrin est placé dans l'espace. Le centre mou de la billette permet pour que les roulements dessinent la billette au-dessus du mandrin, produisant une coquille creuse. Quand la billette a entièrement passé
au-dessus du mandrin, elle est sous forme de tube sans couture profondément muré. Le tube muré lourd est alors passé à un laminoir qui ramène le tube à la tuyauterie de l'épaisseur extérieure appropriée de diamter et de paroi. Dépendant de l'état de processus (la température), tube/pipes sans couture se nomme sans couture sans couture ou étiré à froid de finition aussi chaude que le terme implique. Indépendamment des tubes et des pipes ci-dessus peut être constitué par d'autres processus, comme forgé, tunned, alésé, etc.. dépendant de la condition.
