ASTM A269 TP304 Extruded Fin Tube For Heat Exchanger
ASTM A269 TP304 Extruded Fin Tube For Heat Exchanger
Product Description
The ASTM A269 TP304 Extruded Fin Tube is a high-efficiency heat transfer component made from austenitic stainless steel. The TP304 grade offers excellent corrosion resistance and mechanical properties, while the extruded fin design significantly enhances heat transfer surface area for demanding applications. The integrally formed extruded fin design creates a strong bond with the tube material, maximizing heat transfer efficiency. This construction provides high resistance to oxidation and thermal stress, making it ideal for high-temperature environments.
