Advantages of finned tube

Provide 8 to 12 times the heat transfer area of bare tubes.
     More efficient than bare tubes.

Provide smaller exchangers due to increased Heat Transfer area.
     Often provide a more economical selection.
     Fins can be "Cut & Twist" to increase shell side fluid turbulence and improve heat transfer.

  Applied Fin Tube

Applied Fin Tube is made with strip wrapped under tension around the base of the tube. Fins are welded to the base tube at the strip ends.

According to the wing shape and structure, finned tube can be divided into the following categories:

• Square finned tube
• Spiral finned tube
• Longitudinal Finned Tube
• Helical Serrated Finned Tubes
• Inner finned tube

Carbon steel fins are available on carbon, stainless steel, or copper tube. Please call for a specific size if not listed
