3. Pigging Systems
• Substantially reduce pipe lines
• Virtually eliminates
contamination
• Increases safety of pigging
systems
• Typical Transfer Applications
– Blending to Finished Product
Storage
– FP Storage to filling & loading

5. FMC is using hard PU (92 shore A) flexible lip seals
Others are using soft PU foam ball or sphere

6. Quality of cleanliness
Pressure requested
Passage in Elbows
Acceptance of diameter
variation
Cost of utilization
Is acting as a real swiper. Product
left in a piggable pipe is in the
range of 1 gr / meter.
Is acting as a sponge. Product left
in a piggable pipe is in the range
of 5 to 10 gr / meter.
Thanks to the flexibility of the lips
required pressure is in the range
of 2 to 4 bars max
Because of its design you need to
compress the pig in the line and
need around 6 bars
FMC pig is design to pass through
1.5D elbows
Minimum acceptable radius is 3D
Thanks to the flexibility of the lips
the pig can accept some diameter
variation
Because of its design diameter
variations are not acceptable.
As you only need to change the
cleaning element cost is very low
As you only need to change the
complete pig cost is very high

7. Dedicated Systems
• The use of piggable
distribution valves allows
for
– shortest cleaning time of the
pipe
– the elimination of waste
products or slop resulting in
significant financial savings.
• Same design for launching
station, receiving station,
in line distribution valve
One Function One Item

20. Why use a pigstopper in the launching
station?
• Pigs might be sucked into the line because of the ventury
effect. This will depend on various factor such as:
– Type of pump
– Pressure of transferred fluid
– Viscosity of transferred fluid
– Wear of the pig
– Material of the pig
– Lightening

21. Why use a pigstopper in the distribution
valve?
• We want a mechanical stopper to be sure of the position of
the pig in the line.
– One function, one item.
– Pig velocity can be too high and can damage valve.
• High risk of leakage
– By using a pig stopper, only this one need to be changed

22. Same design for launching station, receiving
station, in line distribution valve
The Valve Compatibility

23. Valve Compatibility
• All components can be dismantle from the main body without
cutting the line

24. Easy Valve Maintenance
• All items can be removed from the body which remain part of
the line

25. The Twin Valve

26. The FMC Twin valve uses
one body for two
products via inlet/outlet
ports.
This compact design
includes the same basic
components as the FMC
