Copper-Nickel & Titanium
UNS C70600, C71500 and applicable titanium grades according to project requirements.
Material selection is based on operating pressure, temperature, process fluid, corrosion conditions, mechanical requirements and applicable project specifications.
90° Long Radius Elbow
The 90° Long Radius (LR) Elbow provides a gradual directional change and is commonly selected for general process and pipeline applications where reduced flow disturbance and smoother routing are preferred.
90° Short Radius Elbow
The 90° Short Radius (SR) Elbow provides a more compact 90° directional change for applications where installation space is limited and the piping design permits the shorter radius.
Seamless 90° Elbow
Manufactured from seamless material for applications requiring seamless construction.
Welded 90° Elbow
Manufactured from welded material where permitted by the applicable material specification and project requirements.
Fabricated 90° Elbow
Custom-fabricated for large diameters, heavy wall thicknesses, special radii or non-standard piping requirements.
Elite can manufacture 90° Elbows according to customer drawings and project requirements, including:
