ASTM B111 C70600 Copper Nickel Low Finned Tube For Boiler
ASTM B111 is a specification standard established by the American Society for Testing and Materials (ASTM) for seamless copper and copper alloy condenser tubes and ferrule stock. This standard covers various grades of copper and copper alloys， including C12200 (copper)， C44300 (admiralty brass)， C68700 (aluminum brass)， and C70600 (90-10 copper-nickel).
ASTM B111 specifies the dimensions， mechanical properties， and other requirements for these condenser tubes and ferrule stock. It includes information on the chemical composition， tensile strength， yield strength， elongation， and hardness of the materials. The standard also provides guidelines for the manufacturing process， heat treatment， and testing methods to ensure the quality and performance of the products.
This specification is commonly used in the manufacturing of condensers， heat exchangers， and other equipment where corrosion resistance， thermal conductivity， and mechanical strength are important factors. It helps ensure that the copper and copper alloy materials used in these applications meet the necessary standards and can withstand the intended operating conditions.
C70600 Copper Nickel Low Finned Tube is a type of tubing used in boilers. It is made from a copper nickel alloy， specifically C70600， which is known for its excellent corrosion resistance and high thermal conductivity.
The low finned design of this tube provides increased surface area， allowing for better heat transfer efficiency. This is particularly beneficial in boiler applications， where heat transfer is crucial for optimal performance.
The C70600 Copper Nickel Low Finned Tube is commonly used in power plants， refineries， and other industrial settings where boilers are used. It is also suitable for marine applications due to its resistance to seawater corrosion.
