35CrMo nahtlose Stahlrohre Spezifikation: 6-1240×1-200mm

①Main production process of hot-rolled seamless steel pipe ( △ Hauptprüfungsprozess):

Vorbereitung und Inspektion von Rohrzuschnitten △→ Beheizung → Einstechen → Rohrwalzen → Wiedererwärmung von Stahlrohren → Durchmessereinstellung (die Ermäßigung) → Wärmebehandlung △→ Fertigrohrrichten → Endbearbeitung → Inspektion △ (zerstörungs, physikalischen und chemischen, Taiwan Inspektion) → warehousing

②Main production process of cold-rolled (gezeichnet) nahtlose Stahlrohre:

Knüppelvorbereitung → Beizen und Schmieren → Kaltwalzen (Zeichnung) → Wärmebehandlung → → Richten → Inspektion Veredelung
