ASTM B111 C68700 Copper Nickel Tube Chemical Composition:

ASTM B111 C68700 Copper Nickel Tube Application:

• Condenser and evaporator: ASTM B111 C68700 copper nickel tubes are commonly used as fittings for condensers and evaporators due to their excellent thermal conductivity and corrosion resistance. In these devices, the tubes need to withstand the flow of high-temperature and high-pressure refrigerant, while also resisting the corrosive effects of the refrigerant. Therefore, the performance characteristics of ASTM B111 C68700 copper nickel tubes make them an ideal choice.
• Heat exchanger: In the chemical industry, heat exchanger is one of the common equipment. ASTM B111 C68700 copper nickel tubes are commonly used as fittings for heat exchangers due to their high strength and good corrosion resistance. These tube fittings need to withstand the flow of high-temperature and high-pressure chemical media, as well as resist the corrosive effects of the media. Therefore, the performance characteristics of ASTM B111 C68700 copper nickel tubes make them the preferred material in the chemical industry.
• Seawater desalination plant: In the process of seawater desalination, a large number of heat exchangers and condensers are required to remove salt from seawater. ASTM B111 C68700 copper nickel tubes are often used as fittings for these devices due to their good resistance to corrosive media such as seawater. The protective oxide layer formed on its surface can effectively resist the erosion of seawater, thereby extending the service life of the equipment.
• Marine platform: In marine platforms, various equipment and pipelines need to withstand the corrosive effects of the marine environment. ASTM B111 C68700 copper nickel tubes are commonly used as fittings for heat exchangers, condensers, and subsea pipelines in offshore platforms due to their excellent corrosion resistance
• Distiller pipeline: During the distillation process, pipelines are required to transport steam and condensate. ASTM B111 C68700 copper nickel tubes are commonly used as fittings for distiller pipelines due to their excellent thermal conductivity and corrosion resistance.
• Other occasions that require corrosion-resistant and high-strength materials: Due to the excellent corrosion resistance and high-strength characteristics of ASTM B111 C68700 copper nickel tubes, they can also be applied to other occasions that require these properties, such as heat exchangers and condenser equipment in industries such as food processing and pharmaceuticals.
