What's New

Inline Services

Inline Services has new tracking equipment that can be used to monitor a pig’s location or movement throughout a pipeline. The pig-tracking equipment consists of receivers, geophones and transmitters. Receivers are used to reveal distinctive pulsing patterns of passing pigs. Geophones detect low sounds helping to indicate where the pig is in the pipeline. Transmitters are available in standard or custom types and operate by emitting electromagnetic fields at low frequencies (between 15-30Hz). Using these devices will help to greatly reduce the search area in the event a pig becomes stuck or lost in the line.
