ASME SB466 UNS C70600 SEAMLESS PIPES

ASME SB466 UNS C70600 SEAMLESS PIPES

ASME SB466 UNS C70600 SEAMLESS PIPES are premium-quality Copper-Nickel (Cu-Ni 90/10) pipes specifically designed for high-corrosion resistance applications, particularly in marine and seawater environments. Manufactured in accordance with ASME SB466 standards, these seamless pipes offer excellent strength, durability, and long service life in aggressive conditions.

UNS C70600, commonly known as Copper Nickel 90/10, contains 90% copper and 10% nickel along with small additions of iron and manganese to enhance strength and corrosion resistance. These seamless pipes provide outstanding resistance to seawater corrosion, biofouling, stress corrosion cracking, and erosion, making them ideal for offshore, shipbuilding, desalination, and heat exchanger systems.
