Fin-fan assembly
Power Fin Technologies has introduced
a fin-fan ‘matrix’ system. The company
claims its new fin-fan matrix construction
is the fastest production machine in the
world.
The product consists of multiple fins
(‘modules’) placed in packs and swaged
onto multiple tube nests 25-50 tubes
wide x 12m long, whilst maintaining
perfect fin spacing, ending up with
a ‘cellular’ damage proof fin-fan unit.
Available ‘add-ons’ include fin spacing,
choice of any fin or tube materials
(titanium, all stainless grades, carbon
steel, non-ferrous), as well as any
tube wall from 0.4mm upwards and fin
thickness of 0.1 to 0.4mm.
Manufacturing time, it is claimed, is
more than halved due to the matrix
application. The 0.4mm thick aluminium
fin is guaranteed to withstand movement
of maintenance personnel across the
surface during outages or damage from
pressure cleaning, and subsequent
rows can be reduced to 0.3mm fins.
Various fin enhancements for optimum
design ensure longevity in the field.
Field trials will be carried out in the New
Year. Engineering director Andrew Price,
designer of the servo assisted hydraulic
machine, commented, “We have
engineered out the soft spirally wound
tubes, the ‘buckle’ clips, and replaced
them with a simple but tough ‘fortress
of stability’ with matching performance
even following high pressure cleaning.”

Anti-corrosion for welded steel tubing
Markin Tubing has over 50 years’
experience of manufacturing low-carbon,
small-diameter, welded steel tube with
technically advanced coating systems,
including durable, formable and versatile
Galfan
®
coated steel tube. Widely used
by industries in North America, Canada,
Europe and Asia, Galfan coated steel
tubing (consisting of a zinc/aluminium
alloy) is used as an alternative to PVF,
PVDF and nylon coatings, as well as
other substrates such as stainless steel,
copper and aluminium. Applied in-line
to the outside surface of steel tubing,
Markin’s Galfan coated steel tubing is
then layered with an aluminium rich
epoxy paint topcoat to enhance the
advanced protective properties.
