ASTM B111 C68700 Copper Seamless Tubes for Condenser, Heat Exchanger Application

ASTM B111 is the standard for seamless copper and copper condenser tubes developed by the American Society for Testing and Materials (ASTM). C68700 is a specific aluminum brass plate number in the ASTM B111 standard, which specifies various technical requirements and performance indicators for this material.

Performance characteristics:

• 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 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 it have good application prospects in equipment such as heat exchangers and condensers that require thermal and electrical conductivity.

Application:

• Condenser and evaporator: ASTM B111 C68700 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 tubes make them an ideal choice.
• Heat exchanger: In the chemical industry, heat exchanger is one of the common equipment. ASTM B111 C68700 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 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 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 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 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 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.
