2008, our customers have created over a thousand jobs in
paint finishing, opened new facilities, expanded existing
ones, and brought millions in production back to the USA.
Improved paint finishing operations have added greater
than $300 million to their businesses. The average
NAPaint project ROI is less than 5 months. Annual
benefit can exceed tens of millions.
PAINT SUPPLY AND DISTRIBUTION SYSTEMS
paint systems incorporate a means of forcing a foam plug (the pig)
through a piping network to recover maximum residual paint.
All system hardware including piping, valves, and fittings must
facilitate this. In addition, there must be a means of
inserting the pig into the system, propelling the pig, and
removing it. Although specialized products such a pig
launchers and catchers are available, they are not necessary for
efficient system design and operation.
recovery of residual paint in the supply and distribution system
for later use holds potentially substantial economic and
environmental benefit. The extent of this potential depends
upon the internal volume of the network, the cost of paint and
disposal, and the frequency which the system must be purged.
The main run of a piggable piping system is installed in a single
loop with the same ID throughout. Paint temperature and
pressure at each drop is more consistent and repeatable than
American Paint Application piggable systems are, by a large
margin, the most efficient available. Complete color change
times are less than 5 minutes and require minimal labor.
After the paint is reclaimed, our purging process minimizes both
time and material to flush and evacuate the system. Loading
paint is fast and easy. This level of efficiency not only
decreases the cost of operations, the speed and flexibility allow
for fewer paint supply and distribution systems needed to support
the production paint process.
components of piggable systems must pass a pig. In most
cases, this requires a new paint supply and distribution
system. In the paint kitchen, inserting and removing the pig
can be a little messy. This method does not reclaim residual
material inside pumps, filters, surge suppressors and other
necessary system components through which the pig cannot pass.
of tubing requires the use of sanitary or compression fittings that will pass a
pig. All fittings must align with the tubing and
orbital welds, if used, must be inspected and reamed for burrs. 90 degree and other bends must be gradual. During
fabrication and installation, care must be taken not to
deform or collapse the internal cross-sectional geometry of the
style color stacks must be used.
Flexible Color Paint Supply and Distribution
North American Paint Application Company is the world leader in
the design of efficient paint supply and distribution systems
requiring the flexibility for multiple colors. Although piggable
systems offer superior performance, existing systems can achieve
good performance and benefit from cost effective alternative methods for reclaiming residual
pipe networks may not need replaced. Neither foam plugs or
other foreign material is forced into the pipe network. And
because residual paint can be largely reclaimed from the pump,
from the filters, and from all system components, less paint
may be wasted.
process utilizes compressed air to push paint from the
system. Because little manual intervention is required, the
whole process of reclaiming the paint, purging the lines, and
loading the next color can be largely automated.
Paint Supply System Flushing and Loading
of the primary purposes of piggable or flexible color systems is
to allow for the supply of multiple colors or materials that share
share the same pipe network. Thorough and efficient flushing
of these systems is very important to prevent cross color
contamination, minimize operational costs, and maintain high
achieve this, all components of the system should have streamlined
internal geometries, free from cavities, crevices and other areas
where paint can accumulate and solidify, or is otherwise not
cleanable. This includes pumps, filtration, surge suppression,
and regulation. Unnecessary restrictions must be eliminated.
these networks can have substantial size and length, straight
solvent purging can require both significant amounts of material
and time, and still be ineffective. The mechanism by which we purge these lines
does not utilize straight solvent purging. We utilize a
turbulent mix of air and solvent for fast and powerful scrubbing
action. It is the
most efficient and cost effective method of purging available and uses a fraction of
the material in a fraction of the time when compared to straight
solvent purging. It requires minimal labor and can be
paint efficiently can have a significant impact on material usage
and quality. First, the system should be designed with
minimum internal volume. This minimizes the amount of paint
required for loading. Second, after purging is complete all
residual purging solvents should be removed from the system.
This allows paint to be loaded without without waste and without
special color systems for efficient flushing and loading is an
extremely important factor in achieving the highest level of
performance from your paint application system.
the correct color must be loaded to the applicator in a timely
manner. If you have existing paint supply systems,
existing color and purge stacks, and existing 1K, 2K, or 3K flow
control equipment, integrating piggable systems to obtain the
color flexibility and performance you require can be difficult
with unexpected results. At one major truck manufacturer
visited recently, poor system design and integration reduced total
paintshop throughput by 10-15%.
