Manufacturing Process Of SS Seamless Tubing

1
Billet / Coil Selection

Certified stainless steel billet or strip chosen by grade

2
Piercing / Strip Forming & Welding

Seamless piercing or TIG-welded strip forming to tube shape

3
Cold Drawing / Sizing

Tube reduced to final OD and wall through draw benches

4
Solution / Bright Annealing

Heat treatment restores ductility and corrosion resistance

5
Pickling & Passivation

Surface oxide removed for a clean, passive layer

6
Straightening, Cutting & Testing

Tube straightened, cut to length and eddy current checked

Seamless Vs Welded Stainless Steel Tubing

Stainless Steel Seamless Tubes
  • No weld seam, extruded from solid billet
  • Preferred for high-pressure instrument loops
  • Higher cost per length
  • Best for critical, safety-rated lines
VS
SS Welded Tubes
  • Formed from strip and fusion welded
  • Economical for large-diameter tube runs
  • Consistent wall thickness across length
  • Widely used in heat exchanger bundles

Stainless Steel Seamless Tubes Temperature Rating

Stainless Steel Grade Maximum Temperature (°C) Maximum Temperature (°F)
304 870°C 1,600°F
304L 870°C 1,600°F
316L 870°C 1,600°F
316 870°C 1,600°F

SS Electropolish Tube Vs Bright Annealed Tube

SS Electropolish Tube
  • Electro-chemical process, mirror bore
  • Lowest Ra value for hygienic lines
  • Preferred for pharma & bioprocess skids
  • Higher finishing cost per metre
VS
Stainless Steel Bright Annealed Tube
  • Heat-treated in controlled atmosphere
  • Bright, oxide-free surface as drawn
  • Preferred for heat exchanger & condenser tube
  • Economical for large-volume orders
