90° Long Radius CuNi Elbow
- GradeCuNi 90/10, C70600, CuNi10Fe1Mn
- RadiusLong radius, commonly 1.5D
- Size Range1/2" - 36" or customized
- Wall ThicknessMatched with connected CuNi pipe
90° Long Radius CuNi Elbow is used to change the direction of copper nickel seawater piping systems with smooth flow transition and reduced pressure loss. Manufactured from C70600 CuNi 90/10 alloy, it is suitable for marine and offshore seawater service.
The long radius design is commonly used in seawater cooling systems, fire main systems, ballast lines and offshore utility water piping where stable flow performance is required.
