Super Duplex Steel Forged Fittings Manufacturer & Supplier

Super Duplex Stainless Steel (SDSS) is used to forge these parts, which provide increased mechanical strength and resistance to stress corrosion cracking, pitting and crevice corrosion. By utilizing a precision-controlled forging process, we shape elbows, tees, reducers, couplings, unions, caps and crosses to exact standards. Our UNS S32750/S32760 Forged Fittings are perfect for industries with high operational demands because they perform exceptionally well in harsh environments where traditional stainless steels may fail.

Benefits of SDSS Socket Weld Forged Fittings

Super Duplex Steel Forged Fittings offer an outstanding balance of strength, corrosion resistance, and weldability, especially in socket weld configurations used in compact, high-pressure systems. Long-lasting performance in harsh operating conditions is ensured by their dual-phase structure and forged integrity.

Outstanding strength-to-weight proportion for structural soundness
Better resistance to stress corrosion cracking caused by chloride
Efficiency and heat transfer are enhanced by high thermal conductivity.
Under thermal cycling, less distortion results from reduced thermal expansion.
Improved mechanical qualities due to the forging process
A longer service life lowers the cost of upkeep and downtime.
Compatible with international standards like ASME B16.11, ASTM A182 and MSS SP-79/83/95/97

Difference between Super Duplex Steel Forged Fittings and Duplex Steel Forged Fittings

Super Duplex Steel Forged Pipe Fittings, such as SDSS S32760 Forged Pipe Fittings, provide significantly higher yield strength (typically over 550 MPa) compared to standard duplex steel, which offers around 450 MPa. The corrosion resistance in Super Duplex, especially against chlorides and acidic media, exceeds that of Duplex due to its higher alloy content (notably Cr, Mo, and N). Furthermore, in deep-sea and offshore applications where duplex grades might perform poorly Super Duplex Socket Weld Forged Fittings exhibit better performance. Super Duplex has a more balanced phase ratio which improves its toughness and weldability even though both grades have a mixed austenite ferrite structure.

Types of Super Duplex Steel Forged Fittings

Manufacturing Types

Threaded Forged Fittings

Designed with internal or external threads, these fittings allow quick assembly and disassembly without welding.
Socket Weld Forged Fittings

These fittings are joined by inserting the pipe into a recessed area of the fitting and welding around it, ensuring strong, leak-proof joints.
Screwed Fittings

Similar to threaded types, screwed fittings are connected using screw threads, making installation simple and cost-effective.
BSPT

Bushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
NPT

End caps are used to seal a pipeline's end, shielding it from impurities and guaranteeing closed systems' safety.

Forms

Forged Elbow

Elbows, which come in 45° and 90° varieties shift the direction of flow with little pressure loss.
Forged Bushing

Bushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
Forged Tee

Used to split or combine flow across three directions essential for branching pipeline.
Forged Coupling

Offer a safe connection between two pipes; threaded and socket-welded options are available.
Forged Plug

Close open pipe ends which are frequently used for isolation or testing.
Forged Cross

With four openings, cross fittings help connect four pipes used when fluid distribution needs to occur in multiple directions.
