What is a Finned Tube Support Collar?

A finned tube support collar, also known as a fin tube clamp, round spacer box, or isolation ring, is a device used to secure finned tubes within heat exchangers and other applications. These collars are essential in maintaining the position and stability of finned tubes, which are utilized to enhance heat transfer in various industries, such as HVAC systems, power plants, and oil refineries.

What is a Finned Tube Support Collar Used For?

The primary purpose of a finned tube support collar is to hold finned tubes securely in place within heat exchangers or similar applications. By preventing movement and vibration during operation, these collars help ensure optimal heat transfer efficiency and reduce the risk of damage to the tubes.

The finned tube support collar can prevent damage to the fins when the finned tubes are assembled as supplied, and can also be used as a support when installing finned tubes on air cooled heat exchangers.

Fin tube collars can be used in high vibration and long tube length applications. Fin tube collars also reduce fin wear which can lead to tube failure.

The design of fin tube support collars can vary depending on the specific application and the type of fin tube used. Some collars may have adjustable features to accommodate different tube sizes or allow for easy installation and removal.

Main Materials of Finned Tube Support Collars

Typically, a finned tube support sleeve consists of a metal collar or clamp that surrounds the finned portion of the tube and holds it securely.

The collar is usually made from a corrosion resistant material to ensure durability and compatibility with operating conditions. Common materials include:

  • Aluminum - Lightweight and corrosion resistant
  • Galvanized Steel - Durable and cost-effective
  • Stainless Steel - Excellent corrosion resistance
  • Silicone Rubber - Flexible and vibration resistant

Finned tube collars offered include cast zinc, silicone, metal band and packed fin. We can also provide mid section (no fins) for customer supplied supports.
