Super Duplex Steel Orifice Flanges are built like tanks for the harshest industrial realities. They combine brutal strength with elite corrosion resistance, standing firm against high pressure, aggressive chemicals, and unforgiving offshore conditions. Engineered for precision flow measurement, these flanges don’t just connect pipelines — they command control and accuracy. With exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking, they thrive where ordinary materials surrender. Used in oil & gas, offshore platforms, chemical processing, and desalination plants, Super Duplex Steel Orifice Flanges deliver unwavering reliability, long service life, and absolute confidence in systems where failure is not an option.
Super Duplex Steel Orifice Flanges are a balanced mix of composition including chromium (24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen with remarkable strength and resistance to corrosion. The flanges have high tensile (typically in the 800 MPa range) and yield (in the range of 550 MPa) strength and possess very good impact toughness at even cryogenic temperatures. The two-stage microstructure of the alloy lends very good resistance to crevice corrosion, pitting, and stress corrosion cracking. Ideal for severe environments, Super Duplex Steel Orifice Flanges are used extensively in offshore, marine and chemical processing industries because of their stable mechanical properties.

Super Duplex Steel Orifice Flanges are used extensively in industries where high strength and corrosion resistance are of utmost importance. They are key components in flow measurement systems, especially in aggressive and high-pressure conditions. Common uses include offshore oil and gas platforms, chemical plants, desalination plants, and marine engineering. They are applied in corrosive fluids, seawater, and high-temperature gases. Their excellent mechanical properties and chloride stress corrosion resistance ensure that they perform well in tough conditions. They are also utilized in power plants and pulp and paper mills to ensure precise flow control and durability over a long period in complex piping systems.
