Edge Tension Finned Tubing

Fin Tube Products, Inc. offers edge tension finned tubes in similar or dissimilar metals. Atmospheric brazing allows for the use of different metals for the fins and the tubes. Therefore, enhancing the heat transfer even more and reducing the overall unit weight of the product.

With our years of experience in manufacturing finned tubes, our edge-tension fin tubes are made with quality in mind using excellent methods and techniques to meet your needs and specifications.

What is an Edge Tension Finned Tube?

An Edge Tension Finned Tube is also known as Edge Wound Finned Tube. These are used in air heat exchangers, oil coolers, and steam generators. This design helps reduce tube vibration, increasing the overall system’s lifespan and efficiency.

The edge-tension fin tubes provide greater longevity for your applications due to their unique design. Furthermore, these finned tubes are highly recommended for moderate duty in regular air ambient applications, such as condensers and evaporators in HVAC or industrial applications.

These are fastened around tubes with a specific tension force to ensure the best heat transfer and efficiency. Furthermore, edge tension finned tubes are used to fix the fins and increase heat transfer efficiency in steel fins.

The Advantages of Using Edge Tension Finned Tubes

The edge tubing finned tubes are popular due to their incredible reliability and performance. Here are some of its benefits:

  • Perfect for low-temperature environments: Edge tubes can withstand extreme low temperatures, making them suitable for use in industrial applications that require heat transfer in low-temperature environments.
  • Larger surface area: They provide a larger surface area that helps in efficient heat exchange.
  • Corrosion-resistant: The edge tubing finned tubes are corrosion-resistant, making them an excellent choice for corrosive environments.
  • Low-cost alternative: Edge-tension finned tubes are an ideal alternative option for low to moderate-temperature applications.

Common applications of Edge Tension Finned Tubes

Edge tension finned tubes are used in different industries for various applications. These are some of the typical applications:

  • Air heat exchangers
  • Oil coolers
  • Steam generators
  • Condensers and evaporators in HVAC units

The edge-tension finned tubes have a standard tubing outside diameter of 1/4″ to 3″ and a tubing length of up to 20′ standard with a 40′ flip available. It can withstand a temperature of up to 250°F, which is ideal for moderate-duty applications.
