Seamless Pipe :
1. The tube billet shall be rolled for three consecutive rolls at first, and the diameter test shall be carried out after extrusion. If the surface does not respond to the crack, the round tube shall be cut by the cutting machine.
2. Then enter the annealing process. During annealing, acid liquid should be used for pickling.
3. After the quality inspection, it shall be strictly selected by hand by the staff, and the surface shall be coated with oil after the quality inspection.
4. If the hole diameter is too large, it shall be straightened. After straightening, it shall be sent to the flaw detector by the transport device for flaw detection experiment, and finally it shall be labeled and placed in the warehouse after specification arrangement.
