Super Duplex Steel Flanges are extensively applied in high-strength and corrosion-resistant industries. They are best suited for offshore oil and gas platforms, subsea pipelines, chemical processing, and marine environments. They are typically employed in pressure vessels, heat exchangers, storage tanks, and piping systems, especially in chloride stress corrosion-exposed environments. Their outstanding resistance to pitting and crevice corrosion qualify them for petrochemical, power generation, desalination, and other severe, high-pressure applications.
