Five Key Benefits to Ultrasonic Metal Loss Inspections 

1. The probability of detection (POD)The probability of a feature being detected by an inline inspection (ILI) tool. is greater or equal to 90%: With exceptional detection capabilities, the ultrasonic metal loss inspection solution detects metal loss features that are as small as 5.0 mm (0.2 in.) in diameter. It also reliably detects features that start at a depth of 0.8 mm (0.03 in.).

3. Detection of several anomalies measure within a small surface area: An axial resolution starting at 0.75 mm (0.03 in.) for an ultrasonic metal lossRefers to the reduction in material thickness or cross-sectional area of a pipe due to corrosion, erosion, or other forms of degradation. solution is recorded – this makes it possible to detectTo sense or obtain a measurable indication from a feature. a high number of measurements within a small surface area to ensure that tiny pittingLocalized corrosion of a pipeline's metal surface, resulting in small, localized pits or cavities. and pinholeA small, localized hole or perforation in the wall of a pipeline with surface dimensions smaller than 1t or 10 mm whichever is greater in length and width direc… anomalies are accounted for within recorded data.

4. Direct measurement principal provides accurate depth sizing: The direct measurement principle provides a depth sizing accuracyThe accuracy with which an anomaly dimension or characteristic is reported. of ±0.4 mm (±0.02 in.) within all common wall thickness ranges. The depth sizing accuracy is consistent whether in thin wall pipes or in thick wall pipes and guarantees precise pressure assessment calculations across different pipe sections.

5. Can be combined with other inspections to provide greater insight into anomalies: Nearly 70% of ultrasonic metal lossRefers to the reduction in material thickness or cross-sectional area of a pipe due to corrosion, erosion, or other forms of degradation. reports are combined with two or more inspections for a greater, more detailed analysis report. This leads to a best possible assessment of a pipeline's condition.
