ASME SB111 C70600 Copper Nickel Alloy Seamless Tube For Heat Exchanger Application
ASTM B111 Standard Specification for Copper and Copper-Alloy Seamless Condenser Tubes
This specification establishes the requirements for seamless tube and ferrule stock of copper and various copper alloys of a specified range of diameters, for use in surface condensers, evaporators, and heat exchangers. The specified coppers and copper alloys are UNS No. C10100, C10200, C10300, C10800, C12000, C12200, C14200, C19200, C23000, C28000, C44300, C44400, C44500, C60800, C61300, C61400, C68700, C70400, C70600, C70620, C71000, C71500, C71520, C71640, and C72200. The product shall be produced by processes such as casting, extrusion, drawing, annealing, straightening, trimming, and other processes which may produce a seamless tube in the specified condition. The coppers and copper alloys shall be specifically furnished in any one of the following tempers: annealed, light-drawn, hard-drawn, or hard drawn and end annealed. Tubes for ferrule stock shall be annealed sufficiently to be fully crystallized. Some tubes are suggested to be subjected to a stress-relieving thermal treatment subsequent to straightening. The products shall be subjected to expansion, flattening, and residual stress tests. The tensile and expansion requirements for the products are specified in accordance with the temper designation. The products shall also be subjected to mercurous nitrate, ammonia vapor, Eddy-current, hydrostatic, and pneumatic tests.
ASTM B111 C70600 Copper Nickel tube offers excellent corrosion resistance, stress corrosion cracking resistance moderately, high strength and last but not least good creep resistance at elevated temperatures.
Applications: Copper Nickel tubes ASTM B111 C70600, are widely used in Steam Turbines, Seawater Desalination Equipments, Petrochemical Plants, Power Plants, Coolers, Boiler, Water Evaporators, Oil Refineries, and Shipbuilding&repair,offshore engineering,shell tubes heat exchnager.Marine air cooler.

UNS C70600 copper-nickel alloy is primarily used in seawater service as forged and machined valve and pump assemblies, fittings and hardware. The alloy is also used in applications where high corrosion resistance and chloride stress corrosion cracking prevention measures prevent the use of stainless steel.
Copper-nickel alloys have excellent resistance to biofouling and marine corrosion, and have good machinability. When nickel is added, copper is stronger and more resistant to corrosion.
UNS C70600 is a copper-nickel alloy with excellent corrosion resistance even in marine environments. The alloy has average high strength and good creep resistance at elevated temperatures, at a higher cost than copper-aluminum alloys and other alloys with similar mechanical properties.
