Cupro Nickel 70/30 Elbow Seawater Corrosion Resistant Butt Weld Fittings ASME B16.9
Cupro Nickel 70/30 Elbow Seawater Corrosion Resistant Butt Weld Fittings ASME B16.9
1.Product Description
Copper Nickel Elbows are manufactured from Cu-Ni alloys (C70600 90/10 or C71500 70/30) for pipeline directional changes. Standard angles are 45°, 90°, and 180°, with Long Radius (1.5D) and Short Radius (1.0D) types. Manufacturing includes seamless push‑forming, hot extrusion, and welded forming. End connections are butt‑weld, socket‑weld, or threaded. Products comply with ASME B16.9, DIN 86090, and EEMUA 146.
