What is a C71500 copper nickel tube?
ASME SB 111 SB 466 C71500 cupronickel alloy is primarily used in seawater operations requiring forged and machined pump and valve components, hardware and fittings. This alloy can also be widely used in areas requiring high corrosion resistance, and where chloride stress-corrosion cracking precautions prevent usage of stainless steel. Applicable for condenser for ship, heat and water supply, chemical industry, desalinator, Condensers, Seawater piping, Power plants, Heat Exchanger shells etc.
