Super Duplex 2507 Flange ASTM A182 UNS S32750 / F53 Super Duplex Weld Neck Flange

ASTM A182 F53 / UNS 32750 / Super Duplex 2507 Weld Neck Flange WNRF Flange

A Super Duplex 2507 Weld Neck Flange is a high-strength, corrosion-resistant pipe connecting component manufactured from forged super duplex stainless steel grade UNS S32750 (ASTM A182 Grade F53). "Weld Neck" is a long, tapered hub that transitions smoothly into the pipe wall via a single butt-weld joint. This flange is defined by its balanced dual-phase microstructure (approximately 50% austenite / 50% ferrite), which provides exceptional mechanical strength and outstanding resistance to localized corrosion in highly aggressive environments. It is fully compliant with the ASTM A182 standard for forged components used in high-temperature and high-pressure services.

Application

You will find this specific flange in environments where both mechanical strength and corrosion resistance are paramount:

• Oil & Gas: Subsea manifolds, offshore platform risers, and high-pressure wellhead equipment (handling sour gas/CO₂/H₂S).

• Chemical Processing: Heat exchangers and piping carrying chlorides, acetic acid, or sulfuric acid.

• Marine/Desalination: Seawater cooling systems and reverse osmosis high-pressure piping.

• Pulp & Paper: Bleaching plants (handling chlorine dioxide).
