Air Cooled L Type Finned tube in tube heat exchanger Al 1060 For Air Fin Coolers
Aluminum L-Foot Finned Tubes are typically used in applications where temperatures do not exceed about 450 degrees F, primarily in air-cooled applications. Other examples include large radiators, such as large compressor oil coolers, and other forced-draft or induced-draft air-cooled applications.
Description:
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”.

ASME SA 179 Specification
ASME SA 179 Carbon Steel Seamless Tubes are Low Carbon Steel Tubes with 0.06-0.18 % carbon content with combination of 0.27-0.63 % manganese. These Tubes are also known as mild steel pipes and tubes. ASME SA 179 Tubes are low-cost Tubes easy to form and shape. These pipes are manufactured as per ASME Specification and commercially referred as cs pipes or ms pipes. Low Carbon Steel Pipes are not as hard as hig carbon steel pipes,Though carburizing can increase its surface hardness.
