The L-shaped fins increase the surface area of the tube, which improves the heat transfer efficiency of the tube. Copper alloy L type finned tubes are typically used in applications where high heat transfer rates are required, such as in air-cooled heat exchangers, process heaters, and other industrial heat exchangers.
Copper alloy is a popular material for finned tubes because of its excellent thermal conductivity and corrosion resistance. Copper alloy L type finned tubes can be manufactured in a variety of sizes and configurations to meet the specific requirements of the application. The number, size, and spacing of the fins can be adjusted to optimize the heat transfer efficiency and pressure drop characteristics of the tube.
The finned tube is used in heat exchangers to increase the surface area available for heat transfer. The fins are typically made of aluminum or copper and are attached to the outer surface of the tube by a process called finning. The L type fin design provides a larger surface area for heat transfer compared to other fin designs.
ASTM B111 is a specification for copper and copper-alloy seamless condenser tubes and ferrule stock. It covers a range of alloys, including C12200, which is used in the manufacturing of the L type finned tube. The specification outlines the requirements for the chemical composition, mechanical properties, dimensions, and tolerances of the tubes.
The copper alloy ASTM B111 C12200 L type finned tube is a heat exchanger tube made of a high-purity copper alloy with a specific fin design that provides an increased surface area for heat transfer. This tube meets the requirements outlined in the ASTM B111 specification.
