Super Duplex Socket weld Fittings

Super Duplex Socket weld Fittings for changes in direction, branching and size transitions, available on MetalMitra in BSP and BSPT to ASTM A182, with mill-certified traceability on every lot.

Super Duplex Socket weld Fittings are forged small-bore pipe fittings with socket weld or threaded ends, manufactured to ASME B16.11 for high-pressure piping and instrumentation lines.

Super duplex stainless steel combines a balanced austenitic-ferritic microstructure with high chromium, molybdenum and nitrogen content, giving very high strength and excellent resistance to pitting, crevice corrosion and chloride stress corrosion cracking.

Product range

• Elbows & Tees — 45° and 90° elbows, equal and reducing tees.
• Couplings & Unions — Full couplings, half couplings and unions.
• Nipples & Swages — Pipe nipples, barrel nipples and swage nipples.
• Plugs, Bushings & Caps — Hex plugs, bushings and end caps.

Why engineers choose it

• High Strength — Roughly twice the yield strength of standard austenitic stainless steels.
• Chloride Resistance — Excellent resistance to pitting and crevice corrosion in seawater and brine.
• Stress Corrosion Resistance — Strong resistance to chloride stress corrosion cracking.
• Weight Saving — Higher strength allows lighter designs in suitable applications.
