Grade 201 Stainless Steel Welded Tube For Acid-Resistant Applications
Stainless Steel Welded Tube
Stainless Steel Welded Tubes:
Made by forming a flat stainless steel sheet or strip into a tubular shape and welding the seam
Common stainless steel grades used include 304, 316, 310, and 430
Have a smooth, uniform surface finish compared to seamless tubes
Offer good corrosion resistance, strength, and durability
Used in a wide range of applications like plumbing, industrial piping, food/beverage equipment, automotive parts, and more
Advantages include cost-effectiveness, consistent quality, and flexible sizing/dimensions
Welding process can be manual (SMAW), semi-automatic (GMAW), or fully automated (GTAW)
Post-weld finishing like pickling, passivation, or polishing may be done to enhance corrosion resistance and appearance
The manufacturing process typically involves:
Coil slitting to width
Tube forming by bending and welding the longitudinal seam
Optional heat treatment for stress relief
Cutting to length
Inspection and testing
Surface finishing (if required)
Common Characteristics:
- Manufactured by welding flat stainless steel strips or sheets into a square or rectangular cross-section
- Available in a wide range of sizes, typically from 10mm to 150mm in width and 1mm to 6mm in wall thickness
- Offered with various surface finishes, such as brushed, polished, or mill finish
- Suitable for structural, decorative, and plumbing applications
