Manufacturing Tpes and Processes of Stainless Steel Pipe

  Manufacturing types and processes of stainless steel pipe

  1. Seamless Hot Rolling Processes

  Round Pipe Billet → Heating → Perforation → Three Roll Skew Rolling, Continuous Rolling or Extrusion → Off Pipe → Sizing (Or Reducing Diameter)→ Cooling → Billet → Straightening → Water Pressure Test ( Or Flaw Detection) → Marking → Storage

  2. Seamless Cold Rolling (Cold drawn) Processes

  Round Pipe Billet → Heating → Perforation → Head → Annealing → Pickling → Oil (Copper) → Multi Pass Drawing (Cold Rolling) → Billet → Heat Treatment → Straightening → Water Pressure Test → Marking → Storage
