Product Specifications
What is Stainless Steel Pipe?
Stainless steel pipe is a hollow, longitudinal steel section with an economical round shape. These pipes are widely used in oil, chemical, medical, food, light industry, equipment manufacturing, and structural applications. With equal twist and anti-twist intensity, stainless steel offers lighter weight advantages for equipment components and engineering structures. Also used in conventional weapons manufacturing for barrels and shells.

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.
