Welding Fin tube , Serrated Type, ASME SA106 Gr.B Seamless Pipe with CS fin material, Raffinate application
Serrated fin tube is a type of heat exchanger tube that has fins with serrated edges. These serrations create additional surface area for heat transfer, allowing for more efficient heat exchange between the fluid inside the tube and the surrounding medium. The serrated edges help to disrupt the boundary layer of air or gas flowing over the fins, improving heat transfer rates.
Serrated fin tubes are commonly used in applications where high heat transfer efficiency is required, such as in air coolers, boilers, and other industrial heat exchangers. The serrated fins can be made from various materials, such as aluminum, copper, or stainless steel, depending on the specific requirements of the application.
