Lord Fin Tube-Helical L Finned tube

What are helical L finned tubes?

The helical L fins provide a larger surface area for heat transfer, which increases the efficiency of the heat exchanger. The "L" shape of the fins is designed to provide maximum contact between the fin and the surrounding fluid, which helps to improve the heat transfer rate. The helical pattern of the fins also creates a turbulent flow of the fluid, which further enhances heat transfer.

Helical L finned tubes usages:

Helical L finned tubes are commonly used in air-cooled heat exchangers, such as those used in power plants and chemical processing facilities. They are also used in other applications, such as in oil and gas processing, refrigeration, and HVAC systems. The type of fin material used in the helical L finned tube depends on the specific requirements of the application, such as the operating temperature, the type of fluid being processed, and the environmental conditions.

The L-shaped aluminum fin tube is standard fin for low-temperature application where some degree of tube wall protection is required. The fin is wound mechanically under tension on to the base tube.Helical Sprial L Type Finned Tube

The strip material is according to controlled deformation below tension giving the optimum contact pressure of the foot of the fin onto the bottom tube therefore maximizing the warmth transfer properties.

The foot of the fin significantly enhances the corrosion protection of the bottom tube.

Helical L finned tubes feature:

Maximum operating Temperature  150°c

Atmospheric corrosion Resistance capacity is acceptable

Mechanical resistance  Poor

Fin materials aluminum, copper

Tube materials  Any

Overall, helical L finned tubes are a highly efficient and effective means of heat transfer, providing significant improvements in heat transfer rates compared to standard tubes. They are commonly used in industrial applications where efficient heat transfer is critical for process efficiency and product quality.
