Finned Tube ASME SA249 TP304 Stainless Steel Welded Tube with Extruded Aluminum Fins
Extruded fin tube: The overall surface of the rolled fin is smooth and free from burrs， making it easy clean. It is produced by compressing tubes， aluminum fin is formed from bi-metallic tubes， a base tube and an aluminum muff tube. When used in heating and air-conditioning systems， the fin surface can be easily wetted and cooled with water for effective cooling. In situations involving drying， heating， and other heat exchange processes， the fin surface is treated with anodizing， resulting in a beautiful appearance and providing effective protection against surface corrosion. Aluminum rolling finned tubes are manufactured by rolling aluminum tubes as a whole. These tubes have the advantage of no contact thermal resistance， high strength， resistance to thermal shock and mechanical shock， excellent thermal performance， and a significant increase in heat transfer surface area. It is widely used in steel， petroleum， chemical， machinery， shipbuilding， power station， hospital， and food industries.

Extruded fin tubes offer several advantages compared to other types of finned tubes:
Enhanced Heat Transfer: The primary advantage of extruded fin tubes is their superior heat transfer capabilities. The extrusion process creates a strong bond between the fin and the tube， maximizing the surface area available for heat transfer. This results in improved heat transfer efficiency and better overall performance.
Increased Durability: Extruded fin tubes are known for their durability and resistance to mechanical damage. The fins are firmly attached to the base tube through the extrusion process， making them less prone to bending， warping， or detaching during operation. This durability ensures long-term reliability and reduces the need for frequent maintenance or replacement.
Improved Thermal Efficiency: The efficient heat transfer provided by extruded fin tubes allows for better thermal management in various applications. They can effectively dissipate heat from hot fluids or gases， making them suitable for heat exchangers， air coolers， condensers， and other heat transfer equipment.
Wide Range of Fin Geometries: Extruded fin tubes offer flexibility in terms of fin geometry. The extrusion process allows for the creation of different fin profiles， such as plain， serrated， or low/high fin configurations. This versatility enables customization based on specific heat transfer requirements， ensuring optimal performance in diverse applications.
Cost-Effective Manufacturing: Extruded fin tubes can be manufactured in large quantities using automated processes， resulting in cost savings compared to other finning methods. The extrusion process is relatively efficient and requires fewer materials and labor， making it an economical choice for mass production.
Corrosion Resistance: Depending on the material used， extruded fin tubes can exhibit excellent corrosion resistance. For example， aluminum extruded fin tubes are commonly used in corrosive environments due to their inherent resistance to oxidation and chemical attack. This corrosion resistance extends the lifespan of the fin tubes and reduces the risk of performance degradation over time.
