Need a dependable duplex fitting? Duplex Steel Buttweld Pipe Fittings on MetalMitra come in seamless, welded and fabricated to ASTM A815, ready for changes in direction, branching and size transitions.
Duplex Steel Buttweld Pipe Fittings are welded pipe fittings that are bevelled and butt-welded to the pipe, creating a continuous, high-strength and leak-resistant connection with smooth internal flow.
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.
Available forms & variants
- Elbows — 45°, 90° and 180° long and short radius elbows.
- Tees & Crosses — Equal and reducing tees and crosses for branching.
- Reducers — Concentric and eccentric reducers for size changes.
- Stub Ends & Caps — Long and short stub ends and pipe end caps.
Performance highlights
- 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.
