Low Finned Tubes are a type of finned tube that features a continuous external fin, helically wound on the base tube with a relatively low height. The main features of low finned tubes are as follows:

1. Increased Heat Transfer: The external fins of the low finned tube greatly enhance heat transfer and enable efficient heat exchange between the fluid inside the tube and the surrounding environment.

2. Compact Design: Low finned tubes have a compact design and provide greater heat transfer capabilities than plain tubes, resulting in smaller equipment sizes and a smaller overall footprint.

3. Reduced Material Costs: The use of low finned tubes reduces the amount of material needed to achieve the same level of heat transfer performance, thus potentially reducing manufacturing costs.

4. Corrosion Resistance: Low finned tubes are often made of corrosion resistant materials like copper or stainless steel which extends the life of the tube and lowers maintenance costs.

5. Increased Efficiency: Due to the increased heat transfer from the external fin, the low finned tube can operate at higher efficiency and lower costs than plain tubes.

Low finned tubes are commonly used in applications such as heat exchangers, air conditioning systems, and power generation facilities.
