(4)Fin product details 
Product Name Material Dimnsion Manufacture Application
G Fin
(Embeded
Fin)
Fin materials:
Aluminium
Base tube
materias:
Any readily machinable material

A helical groove is formed 
in base tube 
displacing of 
material and fin is 
wound 
into the groove under 
tension
 followed by backfilling 
of the 
displaced material to 
lock the
 fin root into the tube
High-efficiency fin
for high operating 
temperatures

Upper limiting 
temperature:

400°C
L Fin
(Wrapped 
Fin)
Fin materials:
 Aluminium 

Base tube :
Any metallic
 material

Fin foot is preformed into L 
shape and 
applied to base 
tube under 
tension. The 
adjacent fins abut 
one another 
giving a degree of 
base tube
 protection for less 
aggressive 
environments
Standard fin for
low-temperature application
where some degree of tube
wall protection is required
Upper limiting temperature:
120°C
LL Fin
(Over-lapped
 L Fin)
Fin materials: 
Aluminium

Base tube:
Any metallic 
material

Fin foot is preformed into an
 LL shape
(overlapped LL) and 
applied to 
base tube under 
tension.
However, foot is pre-shaped to give overlap of one
 foot onto 
another thereby 
improving 
base tube protection 
and 
thermal contact area
Standard fin for
low-temperature applications
giving increased atmospheric
corrosion protection of the 
base tube
Upper limiting temperature:
180°C
K Fin
(Knurled 
L Fin)
Fin materials:
 Aluminium 

Base tube 
materials:

Any metallic 
material
Standard dimensions 
of applied fin tubes:
Base tube dia. (mm):
25.4, 31.8, 38.1,
 50.5, 50.8

Fin height (mm):
9.5, 12.7, 15.88
Fin pitch:
236 to 433 fins/metre
Fin foot is preformed into an
 L shape 
and applied to base
 tube under 
tension. Knurling
 tools both 
precede and follow
 the laying 
down of the fin foot 
so that the 
fin material is 
locked  into the 
preknurled tube. 
This gives up 
to 50% greater
 thermal contact 
area than 
standard L fin and 
also 
ensures an airtight fin to 
tube
 bond, resulting in greater

tube protection
Standard fin 
for medium-temperature
applications, giving increased
atmospheric corrosion
protection to the outer surface
of the base tube
Upper limiting temperature:
250°C
Extruded 
Fin

(Bi-metallic Fin)
Fin materials:
 Aluminium

Base tube 
materials:

Any metallic 
material
Standard dimensions 
of extruded fin tubes:
Base tube dia. (mm):
25.0, 25.4, 31.8, 38.1
Fin height (mm): 
15.88

Fin pitch:
354, 393, 
433 fins/metre
A carefully
degreased core tube is 
fitted into 
an aluminium 
primary tube. This

assembly is then fed into the
triple-spindle finning head 
of the fin-extruding machine.
Three special multi-disc
packs 
extrude the aluminium
 tube into 
helical high fins 
while reducing 
the inner
diameter to give firm

pressure contact with 
the core tube
High-efficiency fins
for higher temperature
applications giving complete and
permanent atmospheric 
corrosion protection of the base
tube. Using over 40% more
aluminium than the equivalent
applied fin the extended fin is
very robust and resistant to
mechanical damage, allowing
the finned tubes to be cleaned
without damage using either
steam or high-pressure water
Upper limiting temperature:
300°C
