Australian Twisted Steel P/L can convert standard tube
and pipe into Corrugated Heat Exchanger tubes. Our Heat Exchanger
Twisty® products range from 3/8 (9.53mm) tube up
to 4 pipe (114.3mm) over a length of 6.000m.
Depending upon flow rates, viscosities and heat transfer rates
of the fluids, Corrugated Heat Exchanger tubes have far greater
heat transfer coefficients over plain, smooth tubes, and even
though frictional losses within the Corrugated tubes are somewhat
higher, the overall efficiency of the tube is generally much better
than that of standard unprocessed tubes. Some studies suggest
that this figure can be as high as 60% Because of this increase
in efficiencies, heat exchangers that use this type of product
can usually be made using less material, giving rise to a more
compact unit. The on going advantages of using Corrugated heat
exchanger tubes is that of lower energy requirements, thus saving
money and the environment. Lower Carbon footprint emissions cannot
be ignored when there is a possibility of a future Carbon tax.
Heat Exchanger Twisty® material can be supplied
with the helical pattern stopping short of the ends. The plain
ends can be used for the fitment of bends, tees, elbows or for
swaging into the end plates if desired. The material can be used
in either of the two ways shown graphically below:
Heat Exchanger Twisty®
range comes in both Left and Right hands. So the inner
tubes can either be the same or opposite hand to that
of the outer tube. Turbulence is the main factor in a
heat exchanger for the thermal transfer to take place.
as In-line mixers. These mixers rely on 2 processes.
1). Turbulent flow to mix.
2). Striations to shear.
2 different styles of material is available in many different
sizes. A hole in Holey Y Twisty® allows
bolting segments together. The mixer can then be taken apart
for cleaning if necessary. Otherwise,
Y Twisty® can be used for the manufacture
of traditional, welded segments. Both styles of segments are
available in both Left and Right hand twists. Having three
edges provides more Striations per segment resulting in quicker,
more efficient mixing
