Pipeline Corrosion Inspection

Accurately addressing and measuring metal loss

The Problem

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

The Solution

At the onset of each project, we identify your unique requirements and tailor our service accordingly. Moreover, you can be sure of especially high-standards of reliability, expertise and responsiveness.

Our Global Engineering Department has the skills and experience to efficiently manage complex and challenging tasks, including dual and multi-diameter, deep-water and bi-directional inspections. For metal loss inspection, we have developed a comprehensive range of proven robots, incorporating ultrasonic technologies. 

Our Ultrasonic Tools

EVO Series UMP

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).

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.
