  A helical groove is formed 
in base tube 
displacing of

of the 
displaced material to 
lock the

  Fin foot is preformed into L

applied to base 
tube under 
tension. The 
adjacent fins abut

Fin pitch:

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 
ensures an airtight fin to 
 bond, resulting in greater

tube protection
Standard fin 
for medium-temperature
applications, giving increased
atmospheric corrosion

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
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
