ⓘSizes like 7/8", 5/8", 3/8" and non-standard metric SS tubing can be ordered directly from the mill. Before placing your order, confirm the OD tolerance as per ASTM A269 or EN 10216-5 standard.

Stainless Steel Tube Weight Chart

Weight per metre helps estimate freight cost, structural load and tonnage pricing. For SS 304/316L, density used is 7.93 g/cm³. Use this simple formula to calculate:W = 0.02466 × t × (D − t) kg/m. Where D = Outer Diameter (mm) and t = Wall Thickness (mm)

Stainles Steel Welded Tube Surface Finish

Wrong Surface Finish Is The Most Common Reason Ss Tube Gets Rejected At Saudi Aramco Inspection, Here's How To Avoid It.

No.1: Hot Rolled, Annealed & Pickled

  • Dull, rough finish from hot rolling process
  • Typically used for large-bore process headers

2B: Cold Rolled, Bright Annealed & Skin Passed

  • Smooth, reflective finish
  • Used for food, pharmaceutical and chemical tubing

BA : Bright Annealed

  • Extremely bright surface without grinding or polishing
  • Preferred for biotech, semiconductor

Polished :180 / 240 / 400 Grit

  • Electropolished finish removes tiny burrs inside the tube, making it bacteria-resistant.
  • Mandatory for GMP-grade dairy, beverage

Compare Seamless vs Welded Stainless Steel Tube

Stainless Steel Seamless Tube

  • No weld seam
  • Handles higher pressure better
  • Required for boilers, high-pressure lines
  • Tighter tolerances and size accuracy
  • Ideal for critical oil & gas applications
  • Available in 3 to 219mm OD
  • Costs 25 to 40% more than welded tube

Stainless Steel Welded Tube

  • Made from steel strip
  • More affordable for general use
  • Available in larger sizes up to 914mm OD
  • Weld seam tested by X-ray or ultrasound
  • Better for thin walls
  • Meets ASTM A249 / A554 / A269 Standards
  • Common in Food, HVAC & Architectural Projects
