ADMIRALTY BRASS SEAMLESS TUBE FOR CONDENSER ASTM B111 / ASME SB111 C44300 / CuZn28Sn1 / CZ111

 

 

Overview:

 

C44300 seamless tube is a type of copper-nickel alloy tube that is highly resistant to corrosion and erosion in seawater environments. It is often used in marine applications, including seawater cooling systems, desalination plants, and submarines.

 

The C44300 alloy consists of 70% copper and 30% nickel, which results in excellent resistance to seawater corrosion, biofouling, and erosion. The alloy also has good strength and ductility, making it suitable for use in high-pressure applications.

 

The seamless tube production process involves drawing a solid copper-nickel billet through a piercing rod to create a hollow tube. This process produces a uniform wall thickness and a smooth internal surface, making the tube suitable for use in high-velocity seawater flow, reducing the risk of internal fouling and erosive wear.

 

The C44300 seamless tube is available in various sizes and thicknesses, and can be customized to meet specific end-user requirements. It is highly resistant to pitting and crevice corrosion and retains its excellent corrosion resistance at high temperatures, making it ideal for use in seawater heat exchangers.

 

C44300 seamless tubes have excellent thermal conductivity and low electrical resistivity, making them suitable for use in heat transfer applications. They are also used in the manufacturing of marine components such as valves, pumps, and seawater intake screens.

Applications:

 

C44300 seamless tubes are commonly used in various marine applications due to their excellent resistance to corrosion and erosion in seawater environments. Some of the common applications of C44300 seamless tubes are:

 

1. Seawater Cooling Systems: These tubes are used in seawater cooling systems for power plants, refineries, and other industrial applications. The tubes' corrosion resistance ensures that the cooling system operates efficiently without the risk of tube failures due to seawater corrosion.

 

2. Desalination Plants: C44300 seamless tubes are used in desalination plants for the production of freshwater from seawater. The tubes' corrosion resistance and good heat transfer properties make them ideal for use in the high-pressure and high-temperature environments of these plants.

 

3. Submarines: These tubes are used in submarines and other underwater vessels due to their excellent resistance to marine fouling and bio-corrosion. This helps to maintain the efficiency and reliability of the vessel's onboard systems, including seawater cooling, hydraulic systems, and heat exchangers.

 

4. Heat Exchangers: C44300 seamless tubes are used in heat exchangers for their high thermal conductivity, good heat transfer properties, and corrosion resistance. They are commonly used in applications such as air conditioning systems, refrigeration systems, and chemical processing plants.

 

5. Valves and Fittings: These tubes are also used for manufacturing valves, pumps, and fittings for use in marine environments due to their excellent corrosion resistance and high-strength properties.
