Pipeline Inspection Gauge (PIG)

A Pipeline Inspection Gauge (PIG) is a device used in pipelines to inspect, clean, and maintain them. It moves through the pipe, driven by the flow of fluids, and collects information about the pipeline's condition. PIGs can detect issues like corrosion, cracks, or blockages, ensuring the safe and efficient operation of the pipeline. They come in various forms, including those designed specifically for cleaning or detailed inspections, and are crucial for preventing leaks and failures in oil, gas, and other fluid transportation systems.
