Finned Tube ， SS304 Stainless Steel Tube With Aluminum Extruded Fins
Extruded fin tubes are commonly used in heat exchangers and other applications that require efficient heat transfer. They consist of a base tube made of a high-performance material， such as stainless steel or copper， with integral fins that are extruded from the tube itself. The extrusion process involves forcing the base tube through a die to create fins along its outer surface. This creates a strong bond between the fins and the tube， ensuring excellent heat transfer efficiency. The fins increase the surface area of the tube， allowing for enhanced heat dissipation or heat absorption， depending on the application.

Why use aluminum fins?
According to the heat exchange application and operation， there are various materials.
The common ones are Aluminum， Alloy， Copper， Brass， Nickel， Titanium， Stainless Steel， Carbon Steel， etc， among which the aluminum and alloy are mostly used.
The basic performance for fin tube heat exchange should be with good solder ability and form ability， higher mechanical strength， good corrosion resistance and thermal conductivity. In spite of these， aluminum and alloy are also featured in extension and higher tensile strength increases under lower temperature. Around all world， especially for low temperature and compact heat exchange， they are widely applied.
The feature of Aluminum
1. Low Density
By alloying and heat treatment， it can reach the structural of construction steel. Suitable for various transportation， especially for small vehicle， reducing weight and consumption.
2. Good Corrosion Resistance
When under harsh conditions， the materials oxide from aluminum is non-toxic. With aluminum heat exchange， no worries that air or liquid inside will be destructed by oxide after long time.
3. Good Thermal Conductivity
Especially suitable for radiating fin， heat transfer evaporator and condenser.
4. High Yielding and resistance to die cutting.
It is easy for processing and forming.
Application of Extruded finned tubes application:
- Operating temperatures less than 300°C;
- Offshore or other remote applications;
- Heat pipes;
- Dry air coolers for air， gas or oil;
- Air to air heat exchangers for HVAC applications;
- Air dehumidification in air treatment plants
- Eenergy recovery in air exhaust system.
