Polished Decorative Tube 201 304 Schedule 10 Stainless Steel Pipe
High-quality stainless steel pipes designed for decorative applications and industrial use, available in grades 201 and 304 with Schedule 10 wall thickness.
Product Overview
Stainless steel pipe is a hollow, longitudinal steel section with a circular cross-section. These pipes are widely used in oil, chemical, medical, food, light industry, equipment manufacturing, and structural applications. Their excellent strength-to-weight ratio makes them ideal for mechanical components and engineering structures.

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 and EFW processes.
