1. Hot rolling (extrusion of seamless steel pipe): round tube blank → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → tube stripping → sizing (or reducing) → cooling → tube blank → straightening → hydraulic test (or flaw detection) → marking → warehousing.
2. Cold-drawn (rolled) seamless steel pipe: round tube blank → heating → piercing → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → hydraulic test (flaw detection) → marking → warehousing.
