ROHRE U. SCHLÄUCHE - NAHTLOS
Ein geheiztes Billet wird in Kontakt mit sich verjüngenden rotierenden Rollen geholt, so daß berechnet in den Raum gezogen wird, der zwischen den Rollen erlaubt wird. Der Dorn wird in den Raum gelegt. Die weiche Mitte des Billets macht es möglich, damit die Rollen das Billet über dem Dorn zeichnen und ein hohles Oberteil produzieren. Wenn das Billet völlig über den Dorn überschritten hat, ist es in Form eines dick walled nahtlosen Schlauches. Der schwere walled Schlauch wird dann zu einem Walzwerk geführt, das den Schlauch auf Rohrleitung des korrekten äußeren diamter und der Wandstärke verringert. Abhängend nach der Prozeßbedingung (Temperatur), wird nahtloses tube/pipes nahtloses oder kaltbezogenes nahtloses des so heißen Endes benannt, wie die Bezeichnung andeutet. Abgesehen von oben genannten Schläuchen und Rohren durch andere Prozesse gebildet werden, wie geschmiedet worden, tunned, gebohrt, kann, usw., abhängend nach der Anforderung.
