ASME SB111 and ASTM B111 are internationally recognized standards that specify the requirements for seamless copper alloy tubes commonly used in heat exchangers, condensers, and similar applications. The C68700 alloy, also known as Aluminum Brass, is a high-performance copper-zinc alloy with excellent corrosion resistance and mechanical properties.
Key Characteristics of ASTM B111 C68700 Copper Heat Exchanger Tube
Corrosion Resistance:
Exceptional resistance to seawater and brackish water corrosion, making it ideal for marine environments.
High resistance to dezincification and stress corrosion cracking.
Mechanical Properties:
Good tensile strength and hardness to withstand pressure and mechanical stress in demanding applications.
Thermal Conductivity:
Excellent heat transfer capabilities, making it suitable for heat exchangers and condenser systems.
Workability:
Easy to fabricate, bend, and weld, allowing for versatile use in various industries.
Durability:
Resistant to biofouling, ensuring long-term performance in harsh environments.
Chemical Composition (C68700 Aluminum Brass)
Copper (Cu): 76.0% - 79.0%
Zinc (Zn): Balance
Aluminum (Al): 1.8% - 2.5%
Iron (Fe): 0.05% - 0.20%
Arsenic (As): 0.02% - 0.06%
Applications of ASTM B111 C68700 Smooth Copper Tube
Heat exchangers for power plants, petrochemical plants, and marine vessels.
Condenser tubes in thermal and nuclear power plants.
Desalination plants and seawater cooling systems.
Other industrial applications requiring corrosion-resistant tubing.
