ASTM A790 Duplex Steel S32205 Welded Pipes

ASTM A790 Duplex Steel S32205 Welded Pipes are corrosion-resistant stainless steel pipes manufactured according to ASTM A790 specifications for demanding industrial applications. Also known as ASTM A790 UNS S32205 welded pipe or Duplex 2205 S32205 welded pipe, these pipes combine high tensile strength, superior resistance to pitting, crevice corrosion, chloride stress corrosion cracking, and excellent weldability. They are widely used in offshore platforms, chemical processing plants, desalination systems, oil & gas pipelines, marine engineering, and power generation industries.

Detailed Information

ASTM A790 Duplex Steel S32205 Welded Pipes Supplier in India

We are a trusted duplex steel S32205 welded pipe supplier, offering premium-quality ASTM A790 Duplex Steel S32205 Welded Pipes manufactured to meet international quality standards. Our pipes are produced using carefully selected Duplex stainless steel, combining approximately 22% chromium, 5% nickel, and 3% molybdenum with nitrogen additions to achieve excellent corrosion resistance and mechanical strength.

As an experienced ASTM A790 duplex pipe manufacturer, we supply pipes suitable for industries where conventional stainless steel cannot withstand aggressive environments. Every UNS S32205 duplex steel welded pipe undergoes strict quality inspections, dimensional verification, hydrostatic testing, PMI testing, and corrosion resistance evaluation before dispatch.

Whether you require standard lengths or customized sizes, we provide reliable piping solutions with quick delivery schedules and complete material traceability.

What is ASTM A790 UNS S32205 Welded Pipe?

ASTM A790 UNS S32205 welded pipe is a duplex stainless steel welded pipe manufactured according to ASTM A790 specifications for seamless and welded ferritic/austenitic stainless steel pipes. The microstructure contains nearly equal proportions of ferrite and austenite, offering significantly higher strength than conventional 304L or 316L stainless steel.

The balanced metallurgy makes duplex S32205 welded pipe highly resistant to localized corrosion, stress corrosion cracking, erosion, and fatigue, making it ideal for demanding industrial environments.
