Production process requirements for seamless tubes
The scope of application of seamless tubes in production and life is getting wider and wider. The development of seamless tubes in recent years has shown a good trend. For the manufacture of seamless tubes, it is also to ensure its high-quality processing and production. I will give you some brief introductions about the production process of seamless tubes here, so that everyone can understand it. The manufacturing process of seamless steel tubes is mainly divided into two major steps: 1. Hot rolling (extruded seamless steel tube): round tube billet →heating →piercing →three-roll cross rolling, continuous rolling or extrusion →stripping →sizing (or reducing) →cooling →straightening →hydraulic test (or flaw detection) →marking →warehousing The raw material for rolling seamless pipe is round tube billet, and the round tube embryo should be cut by cutting machine to grow billets with a length of about 1 meter, and transported to the furnace by conveyor belt. Billet is fed into the furnac...
