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.
