Functions

The very high-resolution XTraSonic in-line inspection tool can measure, produce detailed characterization of and locate:

-	Metal loss features in pipeline walls caused by crevice corrosion, metal erosion and other problems.
-	Geometric defects, such as dents and slotting.

The XTraSonic’s very high resolution provides highly accurate data on pipeline condition and makes it possible to technically and financially optimize post-inspection work.

Technical Process

The XTraSonic in-line inspection tool uses ultrasound technology. The specially developed ultrasound probes guarantee accurate measurement.

Thickness is gauged by accurately measuring the time it takes for the ultrasound beam to travel between the internal surface and external wall of the pipeline.

Geometry is determined by accurately measuring the time it takes for the ultrasound beam to travel from the probe to the internal surface of the pipeline.

The signals are processed and recorded by the onboard electronics, while an odometer accurately pinpoints the location of the signals recorded.

Advantages

The XTraSonic in-line inspection tool can be used to prepare an inspection report that meets the international standards of the Pipeline Operators Forum (P.O.F.). The very high resolution of the recorded data can be used to:

-	Measure defect depth and extent accurately.
-	Apply internationally recognized codes for calculating pipeline strength, such as RSTRENG and API 1160.
-	Ensure optimum technical and financial management of pipeline integrity.

The unique technologies used in the design of the XTraSonic in-line inspection tool mean that inspection quality is consistent in a single run across pipelines comprising sections with different diameters, without having to install expensive intermediate terminals.
