① The main production process of hot-rolled seamless steel pipe (main inspection process):
Tube blank preparation and inspection → tube blank heating → perforation → tube rolling → waste tube reheating → diameter determination (reduction) → heat treatment → finished tube straightening → finishing → inspection (non-destructive, physical and chemical, Taiwan inspection) → storage
② The main production process of cold-rolled (drawn) seamless steel pipe
Billet preparation → pickling lubrication → cold rolling (drawing) → heat treatment → straightening → finishing→inspection
