KL Finned tube

“KL” Finned tube.

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

“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”.
