2205 duplex stainless steel pipe fittings, especially elbows, are widely used in industries requiring high strength, excellent corrosion resistance, and good weldability. China has become a major manufacturing hub for 2205 duplex elbows, offering competitive pricing, diverse specifications, and fast delivery to global markets.
Overview of 2205 Duplex Elbows
2205 duplex stainless steel is a mixed austenitic-ferritic alloy, containing approximately 22% chromium, 5-6% nickel, and 3% molybdenum. This composition provides superior resistance to chloride stress corrosion cracking and pitting compared to standard stainless steels like 304 or 316. Elbows made from this grade are essential for changing the direction of fluid flow in pipelines, with minimal pressure loss.
Common Types of 2205 Duplex Elbows
Elbow Type | Angle | Manufacturing Method | Typical Standards |
---|---|---|---|
Long Radius (LR) | 90° / 45° | Mandrel / Hot Forming | ASME B16.9 |
Short Radius (SR) | 90° / 45° | Cold Forming | ASME B16.9 |
180° Return Bend | 180° | Hot Bending | ASME B16.9 |
