Superior Quality ASTM A182 Duplex Steel UNS S31803 Threaded Flange and UNS S32205 Plate Flange at competitive prices.

"Duplex 22056" might refer to "Duplex 2205," which is a type of stainless steel alloy known for its excellent corrosion resistance and high strength. Flanges made from Duplex 2205 stainless steel would be highly durable and suitable for use in demanding environments, such as those found in chemical processing plants, offshore oil and gas platforms, and marine applications.

Duplex stainless steels like Duplex 2205 offer a combination of properties from both austenitic and ferritic stainless steels, making them particularly well-suited for applications where resistance to stress corrosion cracking and pitting corrosion is essential. Flanges made from Duplex 2205 stainless steel would likely be used in piping systems where corrosion resistance and strength are critical requirements.

01 What are the advantages of Duplex 2205 flanges?

Duplex 2205 flanges offer superior corrosion resistance compared to standard austenitic stainless steels like 304 and 316, especially in chloride-rich environments. They also provide higher strength, which allows for thinner material thicknesses and lighter weight designs. Additionally, Duplex 2205 offers good resistance to stress corrosion cracking and pitting corrosion.

02 What types of Duplex 2205 flanges are available?

Duplex 2205 flanges are available in various types such as slip-on flanges, weld neck flanges, socket weld flanges, threaded flanges, and blind flanges. The choice of flange type depends on the specific requirements of the piping system and the method of joining.

03 What are the temperature limits for Duplex 2205 flanges?

Duplex 2205 flanges have good mechanical properties over a wide range of temperatures, typically from -50°C to 250°C (-58°F to 482°F). However, the specific temperature limits may vary depending on the application and the surrounding environment.
