Tube billet preparation and inspection → tube billet heating → perforation → tube rolling → waste tube reheating → fixed (reduced) diameter → heat treatment → finished tube straightening → finishing → inspection (non-destructive, physical and chemical, bench inspection) → storage
②Main production process of cold rolled (drawn) seamless steel pipe
Blank preparation → pickling and lubrication → cold rolling (drawing) → heat treatment → straightening → finishing → inspection
The production process flow chart of hot-rolled seamless steel pipe is as follows:
