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.
