Helically Wound Finned
Tubes
G Fin
(Embedded Fin) The G fin strip is wound into
a machined groove and securely locked into
place by back filling with base tube
material. This ensures that maximum heat
transfer is maintained at high tube metal
temperatures. Maximum operating temperature
for this fin type is 450°C.
Fin material: Aluminum or copper
Tube materials: Carbon steel, Cr.-Mo.
steel, stainless steel.
L Fins
L Fin strip material is subjected to
controlled deformation under tension giving
the optimum contact pressure of the foot of
the fin onto the base tube thus maximizing
the heat transfer properties. The foot of
the fin considerably enhances the corrosion
protection of the base tube. Maximum
operating temperature for this fin type is
150°C.
Fin material: Aluminum or copper.
Tube materials: Carbon steel, Cr.-Mo.
steel, stainless steel
Crimped Fins
This fin type (crimped fin) is a non taper
fin wrapped under tension around the base
tube. The finning process results in a crimp
forming at the foot of the fin. Fin is then
welded to the base tube at the strip ends.
Maximum operating temperature for this fin
type is 250°C.
Fin material: Carbon/stainless steel
or copper.
Tube materials: Carbon/stainless
steel.
