Super Duplex Buttweld Pipe Fittings

Source Super Duplex Buttweld Pipe Fittings from verified mills, manufacturers and stockists on MetalMitra. Options span seamless and welded, produced to ASTM A815, and every order can ship with an EN 10204 3.1 certificate.

Super Duplex 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.

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.

What you can source

• 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.

Key properties
