ASTM A789 32205 Duplex Stainless Steel Heat-Treated Tube 1/4"-2" OD for Pressure Vessels & Pipelines

ASTM A789 32205 duplex stainless steel heat-treated tubes designed for demanding pressure vessel and pipeline applications. These seamless tubes combine exceptional corrosion resistance with high mechanical strength for industrial environments.

32205 duplex stainless steel combines austenitic and ferritic grade advantages, delivering high strength and superior corrosion resistance. The material demonstrates exceptional resistance to stress corrosion cracking in chloride environments. Heat-treated tubes maintain stable mechanical properties suitable for high-temperature and high-pressure applications, ensuring long-term service life in demanding conditions including seawater, chemical processing, and oil & gas operations.

• Petrochemical platform piping systems: Withstands high temperatures and pressures for corrosive media transport
• Seawater desalination and marine engineering: Resists chloride stress corrosion for extended equipment lifespan
• Pressure vessels and storage tanks: Stable mechanical properties ensure safe operation
• Heat exchanger tubes: Combines high strength and corrosion resistance for high-temperature fluid environments
• Chemical equipment and pipelines: High reliability reduces maintenance costs and enhances process safety
• Energy and power industries: Suitable for high-temperature, high-pressure conditions and corrosive fluid transport

S32205 seamless tubes undergo precision cold rolling and bright annealing to ensure smooth inner/outer surfaces and stable dimensional accuracy. Each tube undergoes pickling, passivation, and rigorous eddy current testing to guarantee zero residual stress and crack-free integrity, meeting stringent requirements for pressure vessels and high-pressure pipelines.
