Pigtek - Acoustic Geophone Pig Tracking Equipment

SHARE
Pigtek Acoustic Geophone Pig Tracking Equipment is designed for monitoring pigs as they traverse pipelines. The system uses sensors to detect vibrations caused by the pig encountering internal features such as weld beads and valves. These low energy pulses are amplified and converted into an audio signal that can be heard through headphones or loudspeakers. Sensor placement can be above ground or directly on exposed pipework, with a cable connecting the sensor to the monitoring unit. Volume and sensitivity can be adjusted to suit operating conditions, and under optimal conditions, the equipment can detect pigs up to 10 km away. Powered by four PP3 batteries, this portable system enables operators to monitor pig movement and estimate velocity based on the timing between weld encounters. The Acoustic Geophone Pig Tracking Equipment complements other tracking systems such as Above Ground Magnetic Pig Tracking Equipment and Electronic Pig Monitoring Equipment. Accurate pig tracking is crucial for pipeline operations including cleaning, inspecting, and clearance, ensuring reliable and safe pipeline management.

Pigtek Acoustic Geophone Pig Tracking Equipment enables pig tracking personnel to listen to a pig as it traverses a pipeline. The system operates by the pig tracking sensor detecting the vibration

generated by the pig as it traverses internal weld beads and other pipeline fittings such as valves, tees etc. These low energy pulses on the pipewall are then amplified and the signal is processed through the control unit to produce an audio output via headphones. The pulses are generated when the cups or discs of a pig encounter internal weld beads between the pipes and fittings.

The pig tracking sensor is placed either in the ground above the pipeline or directly onto exposed pipework. The sensor is connected by cable to the monitoring unit and the audio output can then be heard through headphones or a loudspeaker. Volume and sensitivity controls are easily adjusted to suit the pig tracking operation. In good conditions it is possible to hear a pig using the Pigtek Acoustic Geophone Pig Tracking Equipment at a distance of up to 10 km from the sensor. The equipment is powered by 4 x PP3 batteries.

This equipment will allow the operator to assess whether the pig is moving steadily through the pipeline and by timing between welds the operator can establish the approximate velocity of the pig.

The Pigtek Acoustic Geophone Pig Tracking Equipment is a fully portable system and is an ideal complement to our Above Ground Magnetic Pig Tracking Equipment and Electronic Pig Monitoring Equipment.

Pipeline pig tracking is a valuable aid, if not a critical component of many pigging operations. However, the correct preparation, selection and use of tracking equipment together with the correct pig design, is integral to the overall success.
