1. Product Description
Copper nickel elbows are pipe fittings made of copper-nickel alloy, commonly grades C70600 (90/10) and C71500 (70/30). They are manufactured by hot pushing or cold working followed by annealing, resulting in a uniform microstructure with no residual welding stress. These elbows offer excellent resistance to seawater, brackish water, and various corrosive chemicals, while providing natural anti-fouling properties. They are widely used in shipbuilding, offshore engineering, and chemical pipeline systems.
2.Product Advantages
Outstanding seawater corrosion resistance: Quickly forms a stable oxide film on the surface, with almost no pitting or crevice corrosion during long-term service.
Superior anti-fouling performance: Continuously releases low levels of copper ions, effectively preventing attachment of barnacles, mussels, algae, and reducing cleaning frequency.
Good weldability: Suitable for TIG, MIG, and manual arc welding. No preheating required before welding, no post-weld heat treatment needed. Weld strength and corrosion resistance are comparable to the base material.
Reliable mechanical properties: Tensile strength ≥290 MPa, elongation after fracture ≥30%, capable of withstanding system water hammer pressure and vibration loads.
Full quality assurance: Mill test certificates provided with each shipment. Third-party inspection reports and classification society certificates (ABS, DNV, BV, CCS, etc.) available upon contract agreement.
3.Product Functions
Change pipeline direction horizontally or vertically at preset angles (45°, 90°, 180°).
Maintain smooth fluid flow inside the elbow, reduce turbulence and local pressure drop, and improve system transport efficiency.
Serve as connection hubs in piping networks, combining with straight pipes, reducers, flanges, tees, valves, etc., to form complete conveying systems.
Provide long-term protection of the pipe inner wall under severe corrosive environments, preventing leakage or perforation failures caused by medium attack.
