S32205 duplex stainless steel combines the advantages of both austenitic and ferritic grades. It offers high strength and excellent corrosion resistance. This material demonstrates outstanding resistance to stress corrosion cracking, particularly in chloride environments. When heat treated, the tube exhibits stable mechanical properties. S32205 seamless tube is suitable for high-temperature and high-pressure applications, ensuring long-term service life in demanding environments such as seawater, chemical processing, and oil & gas.

• Petrochemical platform piping systems: Withstands high temperatures and pressures, suitable for transporting corrosive media
• Seawater desalination and marine engineering: Resists chloride stress corrosion, extending equipment lifespan
• Pressure vessels and storage tanks: Stable mechanical properties in heat-treated condition ensure safe operation
• Heat exchanger piping: 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 acid pickling, passivation, and rigorous eddy current testing. This guarantees zero residual stress and crack-free integrity, meeting stringent requirements for pressure vessels and high-pressure pipelines.
