ASTM B111 C68700 Copper Nickel Tube for Condenser, Heat Exchanger Application

ASTM B111 is a standard developed by the American Society for Testing and Materials, officially known as the "Standard Specification for Copper and Copper Aluminum Seamless Condenser Tubes and Ferrule Stock". The products under its standards are mainly copper and copper nickel seamless tubes used for condensers, heat exchangers, and their accessories (such as ring materials). C68700 is a specific copper nickel grade under this standard, belonging to the aluminum brass family.

Why is ASTM B111 C68700 copper nickel tube widely used in the Heat Exchange Industry?

Good corrosion resistance: It has good resistance to corrosive media such as seawater, salt solutions, and acid solutions. In seawater environment, a dense protective oxide layer will form on the surface of the material, which can effectively resist the erosion of seawater and is suitable for equipment such as seawater desalination plants, heat exchangers, condensers, and subsea pipelines on offshore platforms.
High strength: The tensile strength of C68700 copper nickel tube is between 360MPa and 600MPa, and the yield strength is between 80MPa and 540MPa. It has good bearing capacity and is suitable for working conditions under certain pressure and load.
Good processing performance: It is easy to perform cold processing and can be processed into various shapes of tube fittings, such as straight tubes, bend tubes, etc., to meet the needs of different application scenarios. At the same time, its welding performance is also good, and various welding methods such as gas welding and argon arc welding can be used.
Good thermal and electrical conductivity: This makes C68700 copper nickel tubes have good application prospects in equipment such as heat exchangers and condensers that require thermal and electrical conductivity.

The addition of chemical component aluminum can form a hard, dense and highly adhesive aluminum oxide protective film on the surface of the alloy, thereby greatly enhancing the alloy's ability to resist erosion corrosion and cavitation corrosion. At the same time, the arsenic element added as an inhibitor can effectively inhibit dezincification corrosion and can almost completely stop this process.

What applications are ASTM B111 C68700 Copper Nickel Tubes mainly used in?

Power Generation Industry: Condensers in thermal and nuclear power plants are the primary and most classic application for ASTM B111 C68700 copper nickel tubes.
Ships and Offshore Platforms: ASTM B111 C68700 copper nickel tubes can be used in central cooling systems, heat exchangers, condensers, evaporators, and other applications on various ships and offshore oil platforms.
Desalination Plants: In desalination processes, ASTM B111 C68700 copper nickel tubes can be used as heat exchange tubes and pipelines.
Petrochemical Industry: ASTM B111 C68700 copper nickel tubes can be used in cooling water systems in coastal chemical plants.
