Pipeline operators have long identified pinhole and especially embedded pinhole defects as a significant risk factor in their integrity management programs. NDT Global, a leading supplier of ultrasonic pipeline inspection and pipeline integrity management services, announced that it is now offering a high resolution pinhole and pitting (UMp) metal loss inspection service to help operators mitigate such risks.
The UMp service reliably detects defects and sizes as small as 5 mm (0.2 inch) which represents a two-fold improvement in the minimum sizing threshold, from the previous entry level ultrasonic service of 10 mm (0.4 inch), and it will be a standard offering in all of NDT's global markets.
While many inline inspection (ILI) providers still offer corrosion inspections these are without the resolution required to detect and size pinhole defects, with some ultrasonic services only reliably detecting features greater than 10 mm (0.4 inch) and sizing features greater than 20 mm (0.8 inch). 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.
