Metal Loss Inspection

Accurately addressing and measuring pipeline metal loss

Detecting, Sizing and Location of Metal Loss

The integrity of your pipeline plays a critical role in the overall success of your business. Metal loss anomalies such as corrosion and gouging can significantly reduce pipe wall thickness. Against this background, measuring key parameters and determining the safe operating pressure are of the utmost importance.

At the beginning of each project, NDT Global identifies your unique requirements to tailor the service accordingly. Moreover, you can be sure of especially high standards of reliability, expertise and responsiveness. For metal loss inspection, we have developed a comprehensive range of proven tools, incorporating technologies such as ultrasound and magnetic flux leakage.

The pipeline’s integrity is influenced by its environment, the transported medium, the type and state of the coating, the effectiveness of the cathodic protection as well as operational parameters. Flaws and anomalies in the pipe wall can grow from the outside, the inside or even from within. They can appear during manufacturing and construction or later during the operational life of the pipeline.

Metal loss, corrosion and gouging are the most severe anomalies, as these can cause a significant reduction in the pipe wall thickness. Therefore, measuring the remaining thickness of the pipe wall and determining the maximum allowable operating pressure (MAOP) of the pipeline is paramount.

Our Ultrasonic Tools

EVO Series UMP

High resolution pinhole and pitting (UMp) metal loss inspection service as standard in all markets globally. Its complete ultrasonic corrosion inspection tool fleet has been updated to UMp.

The UMp service reliably detects defects and sizes as small as 5 mm (0.2 in) which represents a two-fold improvement in the minimum sizing threshold, from the previous entry level ultrasonic service of 10 mm (0.4 in).

Ultrasonic Corrosion Inspection

Detection of corrosion features with a diameter of 5 mm (0.2 in) reaches a probability of detection level (POD) of more than 90%. Classification and depth sizing is provided for all metal loss defects from 5 mm (0.19 in) on wards. High-resolution river bottom profiles enable accurate defect assessments.
