ASME B111 C70600 B111 C70600-O61 Copper Nickel Low Finned Tube
ASME B111 C70600-O61 Copper Nickel Low Finned Tube is the ultimate marine-grade heat transfer solution for corrosive seawater and brackish environments. Featuring a seamless 90-10 copper-nickel alloy (UNS C70600) base tube in annealed (O61) condition with integral low-profile helical fins, this monolithic design delivers exceptional biofouling resistance, erosion-corrosion immunity, and 40% higher heat transfer efficiency than bare tubes. Ideal for condensers, heat exchangers, and desalination systems operating in chlorides up to 400°C (752°F).
