INTEGRITY ASSESSMENT

Identification of external and internal pipe wall anomalies: e.g. general corrosion, SCC, CUI, pipe deformation and mill features. Our customers use Integrity Assessment for pipelines that cannot be inspected using ILI-tools and where the pipeline condition is unknown. In other words, the remote and non-invasive inspection of unpiggable pipelines around the world becomes possible.

ILLUSTRATIVE VISUALIZATION OF ANOMALY DETECTION

AGIT is able to differentiate between punctual anomalies and areas with an increased probability of failure.

1) Inspection of pipelines with OD up to 42” is possible / 2) Larger WT by request / 3) Dependent on the ground condition (smoothness etc.) / 4) Dependent on outer diameter

It’s for a reason that we are amongst Germany’s Top 100 innovators. Because our mission is to overcome these inspection challenges and, together with our clients, continuously improve the safety and reliability of all pipelines.
