He has now been using the Profiler for nearly six months. The Profiler clearly detected the coke deposit by a change in wall-thickness readings. Groves says that the unit s U-shaped structural positioning arm can be manipulated around pipe fittings, such as bleeders, elbows, supports, and thermowells. And to get higher accuracy, two scans need to be done at 90 apart. Groves verifies that the Profiler can do global inspections on hundreds of meters of insulated or uninsulated piping.
Any areas of concern warrant a crosscheck with a visual inspection and other nondestructive methods.
