Product Description
Large Diameter Stainless Steel Pipe
Factory Grade 304, 316L, 310S, 2205, 321 with Diameter Range 273mm - 630mm
Product Overview
Stainless steel pipe is a hollow, longitudinal steel section with an economical round shape. 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 parts and engineering structures. Also utilized in conventional weapons manufacturing including barrels and shells.
Product Classification
Available as stainless steel seamless pipes and stainless welded pipes. Manufacturing processes include: hot-rolled, extrusion, cold-circular, hexagonal, equilateral triangle, octagonal, and other special-shaped stainless steel pipes.

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.
