ASME SB111 C71500 Copper Nickel Alloy Seamless Condenser Systems Tubes

Material C71500, also known as Copper-Nickel 70/30, is an alloy that consists of 70% copper and 30% nickel, with small amounts of other elements such as iron and manganese. This alloy is widely used in the form of tubes due to its excellent combination of properties, which include corrosion resistance, medium high strength, and thermal conductivity,it has good creep resistance at high temperatures.

YuHong Group, one of the leading suppliers in China, copper alloy seamless pipes and tubes with high quality to our customers and we have sold these tubes in more than 80 countries up to now and have many experiences in exporting.

ASTM B111 / ASME SB111

This specification establishes requirements for seamless tube and ferrule stock of copper and various copper alloys up to 3 1/8 in. (80 mm), inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers.

Advantages

1. Corrosion Resistance: C71500 tubes are highly resistant to corrosion, particularly in marine environments.Because they can withstand the corrosive effects of saltwater without significant degradation,they are often used in seawater applications.

2. Biofouling Resistance: The alloy has natural antimicrobial properties, which make it less susceptible to biofouling (the accumulation of aquatic organisms on surfaces).

3. Thermal Conductivity: Copper-nickel alloys have good thermal conductivity, making them suitable for heat exchanger applications where efficient heat transfer is required.

4. Strength and Durability: C71500 tubes have good mechanical strength and are durable, which makes them suitable for use in harsh environments and under high-pressure conditions.

5. Erosion Resistance: C71500 tubes are resistant to erosion, which is important in applications where there is a high flow rate of fluids.

6. Weldability: The alloy is relatively easy to weld, which facilitates fabrication and repair processes.

Applications

1. Marine Industry: Can be extensively used in the marine industry for piping systems, heat exchangers, and condensers in seawater desalination plants.

2. Heat Exchangers: Due to their excellent thermal conductivity and corrosion resistance, they are used in various types of heat exchangers, including those in power generation, chemical processing, and HVAC systems.

3. Oil and Gas Industry: Can be used in offshore oil and gas platforms for fire water systems, heat exchangers, and other applications where corrosion resistance is critical.

4. Desalination Plants: The corrosion resistance of C71500 makes it ideal for use in the construction of desalination plants, where the tubes are exposed to a highly corrosive environment.

5. Industrial Cooling Systems: Can be used in industrial cooling systems where they are in direct contact with corrosive fluids.

6. Shipbuilding: Can be used in shipbuilding for piping systems, particularly those that carry seawater.

7. Chemical Processing: Can be used in chemical processing plants where they are exposed to corrosive chemicals.

8. Air Conditioning and Refrigeration: Can be used in air conditioning and refrigeration systems, especially in environments where there is a risk of corrosion.
