Fin Type Selection
L, LL, KL, G, extruded and welded fin designs for different temperature duties.
Fin tubes for heat exchangers, air coolers, condensers, boilers and process equipment where higher surface area improves thermal performance.
Product RangeFin tubes increase external surface area and improve heat transfer between tube-side fluid and air or gas flow. They are commonly used in air cooled heat exchangers, economizers, dryers, boilers, condensers and process heating or cooling equipment.
Metnick Alloys supports L, LL, KL, G, extruded, welded and embedded fin tube requirements in carbon steel, stainless steel, nickel alloy, titanium, duplex and copper alloy combinations. Tubes can be supplied straight, U-bent, cut to length or prepared for tube sheet assembly.
