In industrial piping systems requiring unmatched corrosion resistance and structural integrity, ASME B16.5 ASTM B564 UNS N06625 RF socket weld flanges stand as a benchmark for reliability. At Haohao Group, we specialize in manufacturing these high-performance flanges tailored for 300# and 600# pressure classes, adhering to NACE MR0175/ISO 15156 standards to ensure compliance with sour service environments. Available in sizes ¾”, 1″, and 1½”, our flanges are engineered for industries where failure is not an option.
ASME B16.5 ASTM B564 UNS N06625 RF Socket Weld Flange
Why Choose ASTM B564 UNS N06625 Socket Weld Flanges?
1️⃣ Superior Material Properties
- UNS N06625 (Inconel 625): Exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), even in chloride-rich or acidic environments.
- High-temperature strength up to 1800°F (982°C), ideal for thermal cycling applications.
- Fully compliant with NACE MR0175/ISO 15156 for oil & gas, chemical processing, and offshore operations.
2️⃣ ASME B16.5 Design Excellence
- Precision-machined RF (Raised Face) surface ensures leak-proof connections.
- Socket weld design simplifies installation for small-bore piping systems (¾”-1½”).
- Pressure-tested for 300# (PN50) and 600# (PN100) ratings, validated for both static and dynamic loads.
