SENTINEL Pipeline Girth Weld Scanner (GW-4)

The SENTINEL GW-4 is an automated digital X-ray scanner for inspecting pipeline or vessel weldments during new construction with live result on desktop.

Using the latest CMOS X-ray imaging technology, the GW-4 scanner can complete a 3 inch wide, high resolution scan of a 24 inch pipeline in one to two minutes depending on pipe wall thickness. On larger pipe, two or three scanners are run simultaneously.
