Hudson Flanges, Midland, UK, is a renowned manufacturer and supplier of high-quality Super Duplex Steel flanges. Due to their superior strength corrosion resistance and long-term performance our flanges are designed to meet the stringent demands of oil & gas, marine petrochemical and chemical processing industries. We offer a wide range of flange types manufactured from high-quality Super Duplex grades such as S32750 and S32760. With a superb emphasis on accuracy quality assurance and punctual delivery Hudson Flanges is a reliable associate for effective and consistent piping solutions globally.
Super Duplex Steel flanges primarily comprise about 24–26% chromium, 6–8% nickel, 3–5% molybdenum and nitrogen, manganese and trace elements enhancing corrosion resistance. Super Duplex Steel flanges have the benefits of both austenitic and ferritic stainless steels and are stronger and tougher. They typically have a tensile strength of 700–800 MPa and yield strength of about 500–600 MPa Super Duplex flanges exhibit excellent resistance to pitting crevice corrosion and stress corrosion cracking and are best applied in severe conditions such as offshore chemical processing and high-pressure piping systems.

Super Duplex Steel flanges have widespread use in industries requiring high strength corrosion resistance and durability in aggressive environments. They are ideal for offshore oil and gas platforms subsea pipelines and desalination plants due to their resistance to seawater and chloride-induced corrosion. Super Duplex Steel flanges also have extensive application in chemical processing, heat exchangers, pressure vessels, and power generation systems. In marine, pulp and paper, and environmental engineering applications, Super Duplex flanges ensure long-term performance under high pressure and temperature. Their higher mechanical properties guarantee that they will be a reliable choice for demanding applications involving safety and structural integrity.
