ASTM A269 TP304 Stainless Steel Extruded Finned Tube for Heat Exchanger
Extruded fin tubes Stainless steel extruded finned tubes are specialized thermal components designed to enhance heat transfer efficiency in a variety of industrial applications. They combine the advantages of fins—used to increase surface area for heat exchange—with the durability and corrosion resistance of stainless steel. This ensures longevity and performance even in harsh environments.
