"G" Finned Tube
High conductivity fin tube ideal for high temperature applications up to 450℃.
āGā fin have a helical groove formed in the tube surface with an uplift of metal each side which, when peened back into
the fin, grips it securely. This ensures high heat transfer as well as producing a secure mechanical bond.
A wide range of both tube and fin materials are available.
Tube wall must be a minimum of 1.65mm. Groove depth up to 0.3mm.
We can also fin Nominal bore tube from 3/8" to 1 ¼".
