Duplex and Super Duplex UNS S32205 Blind Flanges
The Duplex and Super Duplex UNS S32205 Blind Flange (BF Flange) is a solid disc used to seal the
end of a piping system, a valve, or a pressure vessel opening. It is crucial for isolating sections
of pipe for maintenance, pressure testing, or future expansion. Manufactured by Zeron Fasteners,
these flanges utilize the UNS S32205 (Duplex 2205) alloy, ensuring maximum strength and
outstanding protection against chloride stress corrosion cracking and pitting. Unlike other flanges,
the Blind Flange is subjected to extremely high mechanical stresses due to system pressure acting
directly on its surface. Their primary application is in critical systems, such as offshore
platforms, chemical reactors, and high-pressure fluid lines, where system integrity and resistance
to aggressive media are essential. Zeron Fasteners provides these forged flanges in various pressure
classes, guaranteed to meet ASME B16.5 specifications.
