Super Duplex S32550 Flanges Fittings

Super Duplex Steel UNS S32550 Flanges are engineered to deliver superior strength, corrosion resistance, and durability in highly demanding environments. Manufactured as per ASTM A182 / ASME SA182 standards, these flanges perform exceptionally well in seawater, chemical processing, and oil & gas industries. With lower thermal expansion and higher thermal conductivity than austenitic stainless steels, they are suitable for applications requiring dimensional stability under varying temperatures. These flanges also offer excellent weldability in thick sections, ensuring reliability in critical piping systems. Available types include Slip-On, Weld Neck, Blind, Socket Weld, Threaded, Orifice, RTJ, and Reducing Flanges. Customized dimensions and finishes are also offered at competitive prices.

Duplex Steel S32550 Weld Neck Flanges are widely used for their robust structure and high-pressure handling capacity. Designed as per ANSI B16.5 standards, these flanges provide a secure connection in pipelines carrying corrosive fluids, seawater, or high-temperature gases. With excellent resistance to stress corrosion cracking, erosion corrosion, and fatigue, they are ideal for use in offshore platforms, power generation units, and petrochemical plants. Duplex S32550 Weld Neck Flanges also ensure better thermal conductivity compared to standard stainless steels. Offered in raised face, flat face, and RTJ types, these flanges are manufactured in seamless and forged options. Clients can choose from a wide range of sizes, thicknesses, and pressure classes.
Super Duplex Steel S32550 Blind Flanges are designed to seal off piping systems effectively, ensuring complete shutoff when required. These flanges are manufactured under ASTM A182 standards and are suitable for use in high-pressure and high-corrosion environments such as marine applications, refineries, and chemical industries. With enhanced mechanical strength and resistance to chloride-induced corrosion, they perform exceptionally well even in harsh conditions. The low thermal expansion and higher conductivity make them more reliable than austenitic stainless steels. Super Duplex Blind Flanges are available in various sizes, pressure ratings, and surface finishes, making them suitable for diverse industrial applications worldwide.
Duplex Steel S32550 Slip-On Flanges are popular for their ease of installation and secure leak-proof connections. Known for superior mechanical strength and corrosion resistance, these flanges are manufactured as per ANSI B16.5 and DIN standards. They perform efficiently in oil & gas, marine engineering, and chemical industries where resistance to pitting and crevice corrosion is essential. With excellent weldability and durability, Duplex Slip-On Flanges are ideal for low-pressure as well as moderate-pressure pipelines. Offered in different face types including raised face, flat face, and RTJ, these flanges are supplied in custom-built sizes and pressure ratings to meet diverse industrial requirements.
