ASTM A182 F51 / UNS S31803 / Duplex 2205 Weld Neck Flange WNRF Flange

Duplex Steel WNRF (Weld Neck Raised Face) Flange combines the unique properties of duplex stainless steel with a sturdy flange design. Generally, duplex steel flanges used in high-pressure, high-temperature systems or corrosive environments with available types such as blind, slip-on, weld neck, and socket weld.

Advantages of Duplex S31803 Flange:

High Strength: Greater strength compared to standard austenitic flanges, allowing for thinner walls.
Corrosion Resistance: Excellent in corrosive environments, including chloride-rich conditions.
Versatility: Suitable for various applications in industries like oil and gas, chemical processing, and marine.
