Extruded Fin Tube Stainless Steel ASTM A269 TP304 With Al1060 For Air Cooler
Extruded Fin Tube Stainless Steel ASTM A269 TP304 With Al1060 For Air Cooler
Product Overview
This describes a bimetallic finned tube where a stainless steel core tube is mechanically bonded to an aluminum outer fin. This tube is a key component in an Air Cooled Heat Exchanger (ACHE), where it is used to transfer heat from a fluid flowing inside the tube to the ambient air being blown across the fins.

Advantages of Extruded Fin Tube
-
Excellent Bond Integrity: The fin is integrally bonded to the core tube, resulting in very low contact resistance (the thermal barrier between the fin and tube). This maximizes heat transfer efficiency.
-
Robust and Durable: The fins are very strong and resistant to mechanical damage and fin "loosening," which can happen in other types like L-footed fins.
-
Suitable for High-Temperature Service: The bond remains stable at higher operating temperatures compared to embedded or wound fins.
Applications in Air Cooler
-
Power Plants: For turbine lube oil coolers, closed-loop cooling water systems.
-
Oil & Gas Refineries: Cooling process streams, hydrocarbon liquids, and gases.
-
Chemical & Petrochemical Plants: Condensing vapors and cooling process fluids.
-
HVAC & Compressor Aftercoolers: Cooling air and gases.
-
Food & Beverage Industry: Where hygienic, corrosion-resistant materials are required.
Extruded fin tubes made with TP304 + Al1060 are especially suitable for corrosive or humid environments, such as coastal refineries or open-air installations, where long service life and minimal maintenance are required.
