S31254 Dual-phase Steel Flanges in Various Industries with Material for Secure Connections
Crafted from S31254 super duplex stainless steel (UNS S31254), these premium flanges are engineered to conquer the most aggressive chloride-rich and acidic environments, delivering unmatched performance in offshore oil & gas, seawater desalination, chemical processing, and pharmaceutical industries. With a PREN ≥43 (Pitting Resistance Equivalent Number), they offer superior resistance to pitting, crevice corrosion, and stress corrosion cracking (SCC), even in high-temperature, high-pressure conditions up to 300°C (572°F).
Key Advantages
✅ Exceptional Corrosion Resistance:
High Molybdenum (6%) & Nitrogen (0.35%) Content: Defies chlorides, sulfuric acid, brine, and hypochlorite solutions, ideal for seawater cooling systems, bleach plants, and sour gas pipelines.
Zero Leak Guarantee: Precision-machined RTJ (Ring-Type Joint) or RF (Raised Face) surfaces ensure flawless sealing in critical applications.
✅ Ultra-High Strength & Durability:
Dual-Phase Microstructure (Austenite + Ferrite): Delivers 2x the yield strength of 316L steel (≥550 MPa) with excellent impact toughness for high-vibration, high-load environments.
Resists Erosion & Fatigue: Perfect for abrasive slurry transport, subsea umbilicals, and cyclic thermal stress scenarios.
✅ Cost-Efficient Lifespan:
Outlasts conventional duplex steels (e.g., S31803) and nickel alloys in chloride-rich media, slashing maintenance and replacement costs.
Operates reliably in -50°C to 300°C (-58°F to 572°F), ideal for Arctic pipelines and tropical offshore platforms.
✅ Global Compliance & Traceability:
Manufactured to ASTM A182, ASME B16.5, EN 1092-1, and NACE MR0175/ISO 15156 standards for sour service (H₂S environments).
Full MTC 3.1 material certification, ISO 9001/PED 2014/68/EU compliance, and third-party NDT (UT/PT) reports ensure quality.
✅ Customizable Solutions:
Types: Weld neck, slip-on, blind, threaded, and socket weld designs.
Sizes: DN15 to DN2000, with tailored pressure ratings (Class 150 to 2500), bore alignments, and surface finishes (electropolishing available).
Fast Delivery: Stock availability for standard sizes (DN15-DN600) with 10-day lead time on urgent orders.
