ISONIC EXPERT A-RING software application was created for the detection, imaging, and evaluation of the pitting
corrosion damages in the fillet weld area up to 100 mm (4 inch) inside the above ground storage tanks. This in-service inspection is performed from outside of the tank with use of PA probe situated on the
external lip of the annular ring plate and doesn’t require emptying of the tank so it may be performed at any moment when necessary
Distinguishing and sizing of the following imperfections is provided:
Scattered corrosion at the product side in the critical zone, tank shell and fillet weld areas of the annular ring
Scattered corrosion at the soil side in the critical zone, tank shell and fillet weld, protrusion areas of the annular ring
Compact damages (pitting, etc) at the product side in the critical zone, tank shell and fillet weld areas of the annular ring
Compact damages (pitting, etc) at the soil side in the critical zone, tank shell and fillet weld, protrusion areas of the annular ring

The True-To-Geometrycoverage and imaging allows easy distinguishing between the defects in the annular ring plates and in the fillet welds, which may the allowable incomplete penetration;
the damages situated on the upper and bottom surface of the plate are surely distinguished as well
The movies below illustrate the inspection of the critical zone of the annular ring plate (the fillet weld area continued to up to 100 mm / 4 inch inside the tank) with
use of ISONIC 3510 instrument utilizing either manual or automated scanning
The movie below illustrates the instrument screen (ISONIC 2010) whilst performing scanning of the sample of the annular ring plate with the fillet weld including:
A-Scan Calibration (Calibration of the PA Pulser Receiver)
Entering the Fillet Weld / Annular Ring Plate Geometry and Beam Tracing
Coupling Monitor Calibration
Cross-Sectional View Inspection
Scanning Along the Shell with C-Scan Capturing
Postrpocessing including 3D-Viewing
The video below illustrates the data analysis and interpretation for the record made for a segment of annular ring with real defects
