Fin Tube Products

Fin Tube Products, Inc. specializes in helical-wound brazed finned tubing. We offer several fin-to-tube attachment methods to cater to a wide range of markets.

Our finned tubing and finned pipe are widely used in heat exchangers, boiler economizers, coolers, and heaters. Due to their excellent heat transfer capabilities, finned tubes are an ideal choice for various applications where thermal efficiency is paramount.

At Fin Tube Products, we maintain complete control over the critical brazing process by performing all brazing in-house. This allows us to avoid the potential delays and quality issues associated with outsourcing. As a result, our customers can enjoy shorter lead times and peace of mind knowing that their finned tubes were made with the utmost precision and attention to detail.

We offer the following finned tubing products:

  • Finbraze® Finned Tubing
  • Cladfin®
  • Mini-Fin
  • Edge Tension Fin Tubes
  • Soldered Fin
  • Stamped/Plate Fin
  • “L” Footed Finned Tubing
  • Coils and Bending

Finbraze® Finned Tubing

The brazed finned tubing from Fin Tube Products, Inc. is the most suitable for higher-temperature applications. The Finbraze® process creates a metallurgical bond between the tube and fin, which results in a stress-free, uniform, and non-porous contact, allowing for thinner tube walls compared to a welded fin-to-tube joint.

The Finbraze® process is done in-house with our Controlled Atmospheric Brazing Furnace. Advantages to the Finbraze® production of finned tubing include increased heat transfer, improved strength and durability, and a more cost-effective process. If you need finned tubing for a higher temperature application, look no further than the brazed finned tubing from Fin Tube Products, Inc.

Cladfin®

Cladfin® is a process that applies a nickel chrome coating to the surface of a tube and fin. This coating diffuses into the surface of the tube and fin, creating a high heat and corrosion-resistant bond.

Cladfin® is an alternative to all stainless steel construction, with the added benefit of an increased heat transfer rate. It is suitable for use in high-temperature, high-pressure environments.

Mini-Fin Tubes

Fin Tube Products, Inc. is a leading miniature custom manufacturing company in developing Mini Fin Tubing. They are available in sizes descending from 1/4″ to a diameter as small as .015″. The fin micro tubes are used in various applications in different industries. With our in-house capabilities, we can meet our customers’ specific requirements and preferences.

The mini fin tube is helically coiled and attached to the tube by a soldered or FINBRAZE® fin. Additionally, we collaborate with engineers to create a prototype design that will go through pilot tests.

Edge Tension Fin Tubes

Edge tension tubes are available in similar or dissimilar metals. They are recommended for low-temperature (up to 250°F) air-cooled heat exchangers and moderate duty in normal ambient air applications.

These edge tension tubes offer numerous advantages: This type of fin-to-tube attachment can be used with common carbon steel black pipe and aluminum tubing and various other metals.

Soldered Fin

Fin Tube Products, Inc. offers a soldered fin-to-tube attachment that decreases the amount of solder used compared to a dip process. This soldering method is available with our mini-fin product line.

The soldered fin tubing is good in temperatures up to 375°F. This method of attachment increases the heat transfer of the finned tube. An entire coat/film of insulating solder is formed over the fin and tube surface when coated in solder. As a result, soldered fin tubing is an effective way to prevent heat loss.

“L” Footed Finned Tubing

L-footed fin tubing is designed to provide uniform fin spacing and prevent separation and movement under cycling conditions within the 450°F range.

The L foot provides a greater surface area for the fin to attach to the tubing, and the shoulder edge helps to interlock the fins. This design helps to improve the heat transfer performance of the tubing and prevent potential damage from cycling.
