Pig signal indicators and pipeline tracking equipment are essential to the success of your pigging activities. Being aware of the location of your pipeline pig and being able to easily access it in the event that it becomes stuck can help reduce downtime and alleviate frustration.
What are Pig Signal Indicators?
Pig signal indicators are also known as pig detectors, pig signallers, or pig passage indicators. These tracking devices are installed onto pig launchers or receivers, and used to confirm the launch or arrival of a pipeline pig. Additionally, pig signal indicators can be installed at different points along the pipeline to provide feedback as the pig moves along the line.
Installers typically use a welded fitting or nipple to install the pig detector, containing a trigger mechanism into the pipeline. When the pig moves past the indicator, a signal is activated.
Pig signal detectors can also provide information in the event that the pig is lost or stuck. The fact that the detector is installed at the end of a section of pipeline, makes it easy to detect the location of the pig.
