ASTM A213 T12 Alloy Steel Tube With Stainless Steel 304 Fins， High Frequency Welded Finned Tube
Fin tubes are the main components of heat exchangers. They are tubes where fins have been added on the outside to increase the contact area with the outside fluid to exchange heat and between the fluid inside the tube and the fluid outside the tube.
High Frequency Resistance Welding:
Continuous helical fins are attached to the base tube by high frequency electric resistance welding to give an efficient and thermally reliable bond. Fins can be either solid or serrated. The weld produced in this process is a true forge， which is comprised of a fusion between two portions of parent metal without the introduction of a filler material. The weld is simply produced by heating the interfaces to be joined to a plastic state and adding pressure.
Features Of High Frequency Welded Finned Tubes:
1. Enhanced heat transfer: High frequency welded finned tubes have a larger surface area compared to plain tubes， allowing for improved heat transfer efficiency. This is particularly beneficial in applications where efficient heat transfer is crucial.
2. Increased durability: The welding process used to attach the fins to the tube creates a strong bond， resulting in a more durable and long-lasting product. This makes high frequency welded finned tubes ideal for applications that require a high level of reliability.
3. Customizable design: High frequency welded finned tubes can be customized to meet specific requirements， such as varying fin heights and thicknesses. This allows for greater flexibility in design and enables the tubes to be tailored to the specific needs of the application.
4. Cost-effective: Despite the initial investment in high frequency welded finned tubes being higher than plain tubes， their enhanced heat transfer efficiency can lead to cost savings in the long run. The improved performance of these tubes can result in reduced energy consumption and lower maintenance costs.
5. Versatile applications: High frequency welded finned tubes can be used in a wide range of industries and applications， including HVAC systems， power plants， chemical processing， and oil refineries. Their versatility makes them a popular choice for many different heat transfer applications.
