L finned tube

“L” 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”.
