Duplex Socket weld Pipe Fittings

Source Duplex Socket weld Pipe Fittings from verified mills, manufacturers and stockists on MetalMitra. Options span standard and custom sizes, produced to ASTM A182, and every order can ship with an EN 10204 3.1 certificate.

Duplex Socket weld Pipe 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.

Duplex stainless steel has a two-phase austenitic-ferritic structure that delivers higher strength than standard austenitic grades together with good resistance to pitting, crevice corrosion and chloride stress corrosion cracking.

What you can source

• 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.

Key properties

• High Strength — Roughly double the yield strength of standard 300-series grades.
• Corrosion Resistance — Strong resistance to pitting, crevice and general corrosion.
• SCC Resistance — Far better resistance to chloride stress corrosion cracking.
• Cost Efficient — Thinner walls and long life trim material and lifecycle costs.
