CUNI9010 Butt-welding 90D Long Radius Elbow ASTM B466 UNS C70600 ASME B16.9 for Pipe Connection

This CuNi9010 (UNS C70600) 90-degree short radius butt-welding elbow is a professional marine-grade copper-nickel pipe fitting, fully manufactured per ASTM B466 and ASME B16.9 industrial standards. Different from ordinary steel and stainless steel elbows, the 90/10 copper-nickel alloy features excellent seawater corrosion resistance, anti-fouling performance and stable mechanical properties in salt spray and low-temperature environments. It effectively resists marine erosion, microbial adhesion and chemical medium corrosion, avoiding common failures such as rust, leakage and wall thinning in offshore and seawater piping systems. Adopting integral seamless forming and precision bevel processing, the elbow has uniform wall thickness, smooth inner walls and low fluid resistance. The standard short-radius structure enables flexible installation in narrow spaces, while the fine butt-weld end ensures tight, leak-free connection and long-term operational stability, delivering far better durability than conventional pipe fittings.
