PIGPROX TapGuard Intelligent Pig is a specialized ILI tool for oil pipeline anti-theft inspection, targeting illegal taps and unauthorized branch connections that may cause oil loss, safety hazards and operational risks. Using high-resolution electromagnetic eddy current technology, TapGuard
provides complete circumferential and axial inspection to detect hidden tapping features such as localized openings, wallthickness changes, welded attachments, shallow tapping traces, and thin-wall theft points. The tool and software can be customized to pipeline conditions, with equipment sales,
leasing, and inspection services available.
