What is Stainless Steel Pipe?
Stainless steel pipe is a hollow, longitudinal steel section with an economical round cross-section. These pipes are extensively used in oil, chemical, medical, food, light industry, equipment manufacturing, and structural applications. With equal twist and anti-twist strength compared to other materials, stainless steel offers lighter weight advantages for mechanical components and engineering structures. They are also utilized in conventional weapon manufacturing for barrels and shells.
Classification: Stainless steel seamless pipes and welded pipes
Manufacturing Processes: Hot-rolled, extrusion, cold-circular, hexagonal, equilateral triangle, octagonal, and other specialized shapes

Manufacturing Processes
Seamless Hot Rolling Process:
- 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
Seamless Cold Rolling (Cold Drawn) Process:
- Round Pipe Billet → Heating → Perforation → Head
- Annealing → Pickling → Oil (Copper)
- Multi Pass Drawing (Cold Rolling) → Billet
- Heat Treatment → Straightening → Water Pressure Test
- Marking → Storage
Longitudinal Welding (Straight Seam Welding) Process:
Includes ERW (Electric Resistance Welding) and EFW (Electric Fusion Welding) methods.
