ROFIN's custom finning machines are capable of producing fins in incremental sizes and lengths. In addition, each one of our machines is configured for the specific production requirements of the end user. Every piece is machined to exact tolerances. Because we manufacture our own fin stock, we produce the finest quality tubes...every time.

Finned tubing offers several unique advantages. It provides greater heat transfer by increasing the surface area on the exterior of the tube. It also reduces the unit size for adaptability to smaller space. For example: one foot of helical fin tubing is roughly equal to between seven and twelve feet of plain tubing. Available in a wide variety of base tube and fin combinations, ROFIN LLC can form and assemble helical finned tubing to meet the performance requirements of your specific applications.

Rofin can fin any type of tubing, the most common being:

  • Admiralty
  • Aluminum
  • AL6XN
  • Carbon Steel
  • Copper
  • Cupronickel
  • Sea-Cure
  • Stainless Steel

Some of the advantages of our finned tubes include:

  • Smooth, flat fins reduce friction and dirt accumulation
  • Fins are securely, metallurgically bonded to the tube wall
  • No stress concentrations in tube wall thickness
  • Any tube wall may be used for high or low-pressure application
  • Tube ends fin free to your specifications for joining or expanding purposes
  • Exclusive clip used to hold fin in place while ends are brazed or rolled into header
  • High BTU/foot of tube.
  • Capacity to fin tubes up to 490 inches long
