Erosion Resistant CuNi 70/30 Threaded Elbow, NPT 90° For Pipe Fitting Marine Use
1. Product Description
Copper nickel elbows are pipe fittings manufactured from copper-nickel alloy, with common grades C70600 (90/10) and C71500 (70/30). The products are produced by hot pushing or cold forming processes, followed by solution annealing to ensure uniform microstructure and freedom from residual stress. They offer excellent seawater corrosion resistance, anti-marine fouling properties, and good weldability. Various connection types are available, including butt weld, socket weld, threaded, and flanged ends. These elbows are widely used in marine engineering, shipbuilding, petrochemical, and power generation industries.
2.Product Applications
Copper nickel elbows are suitable for shipbuilding (cooling water, ballast, and firefighting systems), offshore oil and gas platforms, desalination plants, power plant cooling systems, petrochemical corrosive media transmission, as well as heat exchanger and condenser piping networks. They are particularly recommended for seawater and high-salinity brine environments where corrosion
3.Product Advantages
Excellent seawater corrosion resistance: The alloy naturally forms a protective oxide film, providing superior resistance to pitting, crevice corrosion, and erosion-corrosion even at high flow velocities.
Anti-marine fouling: The surface releases trace copper ions that inhibit the attachment of barnacles, mussels, and algae, significantly reducing cleaning and maintenance frequency.
Good weldability: No preheating is required before welding, and no post-weld heat treatment is necessary. The weld zone maintains corrosion resistance comparable to the base material.
High mechanical strength: Annealed tensile strength ≥290 MPa, yield strength ≥105 MPa, and elongation ≥30%, ensuring long service life under mechanical stress and vibration.
International compliance: Manufactured according to ASME, DIN, and GB standards. Third-party inspections and classification society certifications (ABS, DNV, BV, LR, CCS) are available upon request.
