Pathfinder
Pigs:
The history of
magnetic
pigging technology dates back to 1970 when
Ernest Casey, working on
British Gas Pipelines, developed and
patented a process for monitoring
and locating lost/obstructed pigs. Since
that time there has been major
advances in electronics, magnetic and
communications technologies.
StarTrak has taken every advantage of these
new and exciting
developments.

StarTrak’s
“Pathfinder”
modular magnetic pigs are designed to
saturate the wall of the pipeline
through which they are traveling. Pig size
range from 3” to 48”, which
cover most aspects of operational pipeline
systems. In order to achieve
the required field strength necessary to
provide detection of pigs that
may be obstructed, specially designed
magnetic modules are inserted
into pole plates thus causing the magnetic
flux to be guided to the
wall of the pipe. System patented by Ernest
& Ian D Casey.
All
pigs are
constructed to
provide the strength necessary for varying
operating conditions for oil
& gas pipeline system, on and off shore.
Pigs are detectable to a
depth of 15 meters, 10 meters for 4”-6”
pigs.
All
“Pathfinder”
pigs utilize
a high grade of urethane cup or disc also
urethane spacers that save on
maintenance and in addition provide a shock
absorbing effect. Pigs are
equipped with optional by-pass facilities
and may also be utilized with
brushes or blades.
In
addition
to the
unique magnetic detectability features,
“Pathfinder”
pigs
also collect magnetic debris during their
operations.
