Oil & Gas CuNi 70/30 Copper Nickel LR Elbow, 3R Bend ASME B16.49 Anticorrosive
1. Product Description
Copper nickel elbows are pipe fittings manufactured from copper-nickel alloy, typical grades C70600 (90/10) and C71500 (70/30). The products are formed by cold pushing or hot pressing, followed by solution annealing to eliminate internal stress. These elbows offer excellent resistance to corrosion, erosion, and biofouling in seawater, fresh water, and various corrosive media, making them a common choice for shipbuilding, offshore engineering, and chemical piping systems.
2.Product Applications
-
Shipbuilding & repair: Seawater cooling, ballast, firefighting, and tank cleaning lines.
-
Offshore engineering: Seawater lift risers and water injection pipelines on platforms.
-
Desalination plants: High-velocity seawater transmission and brine discharge lines.
-
Power industry: Circulating cooling water systems in nuclear and thermal power plants.
-
Petrochemical: Pipelines for corrosive media containing hydrogen sulfide or chloride ions.
-
Heat exchangers: Inlet and outlet connections for heat exchangers and condensers.
3.Product Functions
-
Change fluid flow direction in pipelines (standard 45°/90°/180° or custom angles).
-
Maintain stable flow pattern at bends, reduce local resistance coefficient, and lower pumping energy consumption.
-
Serve as directional nodes in piping networks, combining with straight pipes, flanges, tees, reducers, etc., to form complete systems.
-
Provide long-term protection against corrosion in aggressive environments, extending overall system service life.
