Product Description
TP304L Stainless Steel Pipe Tube SS Pipe ASTM A312 Stainless Steel 304L
Stainless steel pipe is a hollow, longitudinal steel section with an economical round shape. Widely used in oil, chemical, medical, food, light industry, equipment, apparatus, and structural applications. With equal twist and anti-twist intensity, stainless steel offers lighter weight, making it ideal for equipment parts, engineering structures, and conventional weapons production.

Manufacturing Processes
Stainless steel pipes are categorized into seamless and welded types with various manufacturing methods:
- Seamless Hot Rolling: Round Pipe Billet → Heating → Perforation → Three Roll Skew Rolling/Continuous Rolling/Extrusion → Off Pipe → Sizing → Cooling → Billet → Straightening → Water Pressure Test → Marking → Storage
- Seamless Cold Rolling (Cold drawn): Round Pipe Billet → Heating → Perforation → Head → Annealing → Pickling → Oil (Copper) → Multi Pass Drawing → Billet → Heat Treatment → Straightening → Water Pressure Test → Marking → Storage
- Longitudinal Welding (Straight seam welding): Including ERW and EFW processes
Industry Standards & Applications
