Question 1

What are  Duplex Steel S31803 Flanges?

Accepted Answer

Duplex Steel UNS S31803 Flanges are manufactured using a duplex stainless steel alloy. This alloy provides excellent resistance to corrosion and is particularly resistant to stress corrosion cracking. It also offers greater strength than other austenitic stainless steel, making it perfect for high-pressure uses. These flanges come in blind, slip-on, and weld neck designs to accommodate applications and possess favorable weldability characteristics. ASME 16.5 Duplex Steel UNS S31803 Flanges can be utilized in temperatures ranging from -50°F to 1200°F.

Question 2

What are the standard specifications for Duplex Steel S31803 Flanges?

Accepted Answer

Duplex Steel S31803 Flanges are commonly produced to meet global standards for size and strength specifications, such as ASTM A182, ASTM A240, ASTM A276, ASTM A479, and ASME B16.5 or ASME B16.47.

Question 3

What is the Duplex Steel S31803 Flange used for?

Accepted Answer

Duplex Steel S31803 Flange is designed for applications that require superior corrosion resistance compared to S31803. S31803 is a duplex stainless steel grade with enhanced resistance against pitting and crevice corrosion. These flanges are widely utilized in environments that contain chloride ions, including seawater applications, desalination plants, and chemical processing plants.
