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)
Includes ERW (Electric Resistance Welding) and EFW (Electric Fusion Welding) processes.
