Evo Series 1.0 UMp

Detection and sizing of pinhole and embedded pinhole defects

Pinhole and embedded pinhole defects are a significant risk factor in integrity management programs. To manage these risks, a solution with higher-resolution inspection of features identifies the true deepest point of a pinhole morphology within a larger area of corrosion with an overall shallower depth.

NDT Global offers high-resolution pinhole and pitting (UMp) metal loss inspection service as standard. The UMp service reliably detects defects and sizes as small as 5 mm (0.2 in) diameter, which represents a two-fold improvement in the minimum sizing threshold, from the previous entry level ultrasonic service of 10 mm (0.4 in).


  • Circumferential resolution 4 mm (0.2 in)
  • Minimal axial resolution 0.75 mm (0.03 in)
  • Metal loss inspection, quantitative wall thickness measurement with pitting resolution
  • Provides the best resolution for pitting detection and sizing
