Engineered for Harsh Environments

Super Duplex Flanges are specifically designed to withstand the most challenging conditions, offering outstanding performance in corrosive settings such as marine and petrochemical industries. The exceptional toughness and resistance to cracking under stress make them a preferred choice for critical applications.


Comprehensive Quality Assurance

Every flange is rigorously tested using radiography, PMI, hydrostatic, ultrasonic, and visual inspections, ensuring full compliance with global standards. These robust quality checks guarantee product integrity, even under high pressure and extreme temperature fluctuations.


Versatile Applications

With superior strength, excellent weldability, and a variety of connection types, our Super Duplex Flanges address diverse operational needs. Their reliability makes them suitable for oil & gas, chemical processing, power generation, desalination plants, and more.

FAQs of Super Duplex Flanges:


Q: How are Super Duplex Flanges manufactured to ensure high quality?

A: Super Duplex Flanges are produced using a hot forging process followed by precise machining. This method ensures superior mechanical properties, tight tolerances according to ASME/ANSI B16.5 and B16.47 standards, and a polished surface for optimal performance in critical settings.

Q: What testing procedures are performed on these flanges?

A: Each flange undergoes 100% radiography, positive material identification (PMI), hydrostatic, ultrasonic, as well as visual and dimensional inspections. These rigorous tests ensure structural integrity, correct material composition, and adherence to relevant industry standards.

Q: When should I choose a Super Duplex Flange with a specific face type (RF, FF, RTJ)?

A: The selection depends on the application requirements: RF (Raised Face) is common for general services, FF (Flat Face) is suited for mating with flat-faced components, while RTJ (Ring Type Joint) is preferred in high-pressure or critical sealing environments.

Q: Where are Super Duplex Flanges commonly used?

A: They are widely utilized in oil & gas facilities, chemical processing plants, marine environments, power stations, petrochemical industries, and desalination operationsanywhere superior corrosion resistance and high strength are critical.

Q: What are the main benefits of using Super Duplex Steel (UNS S32750/S32760, 2507) for flanges?

A: Super Duplex Steel offers high purity, excellent corrosion resistance in seawater and chloride-rich environments, superior mechanical strength, and outstanding weldability, making it ideal for demanding industrial applications.

Q: How does the packaging ensure the safety of Super Duplex Flanges during shipping?

A: Flanges are packed securely in wooden cases or on pallets, with plastic wrapping for added protection. This packaging approach prevents transit damage and preserves the pristine finish and dimensional accuracy of each flange.
