Product Description

The Austenitic Stainless Steel Welded Pipe is manufactured from high-quality austenitic stainless steel coils or sheets, formed into a cylindrical shape, and longitudinally welded using advanced Tungsten Inert Gas (TIG) or Laser welding technologies. Austenitic grades are characterized by their face-centered cubic crystal structure, which provides excellent formability, toughness at cryogenic temperatures, and outstanding corrosion resistance. This welded pipe offers a cost-effective alternative to seamless pipe while delivering reliable performance in a wide range of industrial applications.

Key Features of Austenitic Welded Pipe
  • Excellent Corrosion Resistance – Resists oxidation, organic acids, and many inorganic chemicals

  • Good Formability – Can be bent, flanged, and swaged without cracking

  • Toughness at Low Temperatures – Retains impact strength down to cryogenic ranges (-196°C)

  • Non-Magnetic – Low magnetic permeability in annealed condition

  • Cost-Effective – Lower cost than seamless pipe for equivalent wall thickness

  • Consistent Wall Thickness – High dimensional accuracy from coil feed stock

  • Wide Size Range – Available in large diameters up to 48 inches (1219 mm)

Applications
  • Chemical and Petrochemical – Low to moderate pressure process lines

  • Food and Beverage – Dairy, brewery, juice, and edible oil piping

  • Pharmaceutical – Clean steam and purified water distribution

  • Water Treatment – Potable water, reverse osmosis, and wastewater lines

  • HVAC and Plumbing – Chilled water, condenser water, and heating systems

  • Architectural – Handrails, guardrails, and decorative structures

  • Paper and Pulp – Low-corrosion service lines

  • Fire Protection – Sprinkler system piping (NFPA compliant)

  • Automotive – Exhaust system components (400 series available)

    Precision cold rolled stainless steel strip is a narrow, thin-gauge stainless steel product manufactured to significantly tighter thickness and width tolerances than standard cold-rolled sheet. Unlike standard sheet (typically 1000mm or 1219mm wide), precision strip is produced in narrow widths — usually less than 600mm — and thin gauges from 0.05mm up to 3.0mm. The key differentiator is the tolerance : the precision strip holds thickness variations to as low as ±0.005mm,
