Non-destructive testing (NDT) is precisely as its name suggests -- testing that's done without destroying or affecting the integrity of analyzed pieces. From the oil and gas industry to manufacturing and fabrication, various sectors utilize NDT and non-destructive examination (NDE).

NDT and NDE can be used to detect and size flaws and irregularities.  Identifying surface and subsurface issues while the equipment is in-service makes NDT an appealing cost effective solution.
