EES Piggable Paint Circulation Systems

|
EES Piggable Paint Circulation Systems Primarily
developed for the oil and gas industries, pigging systems were created to clean the piping as well as recover the valuable
material remaining in the pipeline. Over the years, this technology has been transferred to many different manufacturing
processes including food & beverage, pharmaceuticsl and industrial aaplications such as paint.
Regardless
of the industry, the basics of a pigging system are centered on the pig, the pig launcher, piggable valves and a pig receiver.
Maximize Paint Recovery EES
piggable systems enable our customers to recover more than 95% of the existing material inside the pump module and tubing
out ot the spray booths.
Minimize Solvent Usage & Labor System design keeps solvent usage to less than 2 gallons per color change.
Quick disconnects and ease of use features allow cleaning and loading new colors in less than 30 minutes.

Pigs & Piggable Valves
Pigs come in many shapes and sizes depending upon the application. For paint, pigs are typically small polyurethane
foam, bullet-shaped objects. Their outer diameter is slightly larger than the inside diameter of the tubing to be cleaned
in order to provide an good seal against the tubing wall.
Piggable color change valves allow the pigs to pass as close as possible to the color change manifold to mininize any
dead spots between the valve and manifold.
Pig Launchers & Receivers
Pig launchers and receivers are the mechanical means for inserting and removing the pig. Launchers
are equipped with a gas connection that is used for pushing the pig through the tubing network. Receivers provide the
means to recover product and the pig.
Launchers are located after the supply filter while the receiver is installed prior to the backpressure regulator.
In between, the paint tubing is installed in a ring loop configuration to the paint stations.
Depending upon the paint system configuration, piggable color change valves may direct paint straight to the
gun or to a port on a traditional color change valve assembly. It is not uncommon to install piggable valves integrated
with a traditional color changer stack assembly.

Reduce Maintenance & Operational Costs:
Wear and tear on pumping equipment is greatly reduced by eliminating the 24/7 circulation requirements of traditional
piping systems. The piggable systems can be cleaned and emptied at the end of daily production. Plant compressed
air consumption is also lowered by only supplying pumps during production.
Lower Capital Expenditures:
As noted, piggable systems are easy to clean and load new colors. Due to this fact, 4 piggable systems
can provide the same capacity as up to 12 traditional systems.
