Finned Tube

Economically produced fin tube for moderate working temperature up to 150ºC

“L” finned tube relies on maximum surface contact between fin and tube which is ensured by tension forming fin strip helically around the base tube.

A considerable degree of protection is given to the tube by the base of the fin.

We can also fin Nominal bore tube from 3/8” to 1 ¼”.

Double “L” fin is used on applications requiring additional protection to the surface of the base tube.

It is produced similar to “L” fin but has a wider fin base which is overlapped during the winding process.

Maximum operating temperature 175ºC.

We can also fin Nominal bore tube from 3/8” to 1 ¼”.

“KL” finned tube relies on maximum surface contact between fin and tube which is ensured by tension forming fin strip helically around the pre knurled tube offering an improved bond and heat transfer.

A considerable degree of protection is given to the tube by the base of the fin.

We can also fin Nominal bore tube from 3/8” to 1 ¼”.

High conductivity fin tube for high temperature applications up to 450ºC.

“G” fin have a helical groove formed in the tube surface with an uplift of metal each side which, when peened back into the fin, produces a firm mechanical bond.

Tube wall must be a minimum of 1.65mm. Groove depth 0.3mm.

We can also fin Nominal bore tube from 3/8” to 1 ¼”.
