We are hearing about global warming and how
this problem that it seems we are creating is going to affect
all our lives both now and in the future. We are all being
asked to help cut down our use of power consumption so that
in turn we decrease the demands that we are making on the
power stations that generate our electricity.
One way that will most definitely HELP
reduce our contribution to global warming will be to look
at ways that we can practically reduce the amount of power
that we consume on a daily basis in our plants is by utilising
the benefits that THISTLEBOND EFFICIENCY COATINGS
can provide.

| HOW Thistlebond Polymers
CAN dramatically IMPROVE your PUMP and SYSTEM performance!
and in doing so REDUCE YOUR OVERHEAD costs and INCREASE YOUR
PLANT PROFITABILITY!! |
 |
The passage of liquids through
pumps and associated pipework can be severely affected by
the nature of the surface involved.
In 1846 Poisevilkle and a few years later, Darcy first developed
equations which recognised changes in liquid flow. These equations
were later refined by Reynolds who conceived "direct"
or "streamlined flow" and "turbulent flow".
Reynolds work was further developed by later scientists who
refined the concept of flow leading to the Reynolds Number,
and the recognition of the adverse effect of SURFACE ROUGHNESS
on fluid flow. |
|
|
Surface roughness can be caused by a number
of factors including CORROSION, IMPINGEMENT, CAVITATION
and ENTRAINMENT. Furthermore, even an apparently
smooth metal surface can be shown to be relatively uneven
under a microscope.
Whatever the cause of surface roughness however, the elimination
of this problem can be achieved by using specially formulated
Thistlebond polymer coatings.
|
Thistlebond have been at the
forefront of liquid flow coatings development for over 30
years. The company pioneered the development of epoxy coatings
for use on both oil and gas pipelines. Thistlebond have become
world leaders in the use of such coatings on:
Pumps | Valves | and Pipelines
within the Industrial Manufacturing and Service Industry Sectors.
More recently, the company has carried out extensive research
into FLOW COATINGS for Pumps and Pipework
handling aggressive fluid mixtures. This research has led
to the introduction of a new and advanced polymer based coating
which combines a high degree of corrosion and chemical resistance
with outstanding abrasion resistance and enhanced flow characteristics.

This product has been introduced under the
brand name of THISTLEBOND TR210 SUPER LOW FRICTION
EFFICIENCY COATING, and has already achieved spectacular
success as a high performance coating for use on:
Pumps | Valves | Impellers | Pipework
where a protective coating with LOW FRICTION SURFACE offers
significant advantages over conventional systems.
A two-coat system of THISTLEBOND TR210 affords
a high degree of protection to steel surfaces, furthermore
by combing a new generation of LOW FRICTION POLYMERS,
the system providing a smooth low friction surface which improves
flow rates and makes a SIGNIFICANT contribution towards ENERGY
SAVINGS (REDUCED KILOWATT HOURS).

Independent tests**
show that in two separate experiments a pump efficiency improvement
of 8% would be achieved when comparing a coated pump against
an equivalent uncoated pump.
From an identical power input of 166 k-watt, a coated pump,
had an efficiency of 85% against 77% for uncoated pump. This
level of improvement can be translated into considerable energy
savings for the same volume of liquid pumped.

| Is the efficiency
of the pump important? Most certainly YES!! |
Pumps are selected in general from pump manufactures
pump performance curves.
Required Flow | Required Head / Pressure | Pipe Sizing | Restrictions
in System | Specific Gravity | Temperature | Liquid
With all the above information the pump is the selected that
suits the industry and part of the selection process is based
upon the BEP (Best Efficiency Point). This
is the point on the Pump Curve where the pump operates best.
Whilst pump companies allow pump operating if the pump operates
OFF the recommended BEP (50% to left | 25%
to right) to maintain MAXIMUM EFFICIENCY and therefore MINIMUM
k-watt power consumption (minimum financial cost) the pump
need to remain as close as possible to the initial design
and surface tolerances.
|
|
IF these change (or for instance
PIPE work that feeds the pump becomes corroded - changes ID
size through restrictions caused by pumped product STICKING
against the pipe internal diameter) then the pump becomes
inefficient and in doing so COSTS MORE TO OPERATE.
IN CONCLUSION IF YOUR COMPANY CAN SAVE ? K-WATT HOURS BY USING
SUPER LOW FRICTION EFFICIENCY COATING THEN THIS CAN BE TRANSLATED
IN MONETARY TERMS TO £ (check with your account HOW
Much he is paying for a k-watt hour)
