The Short Range Guided Wave Ultrasonic Test (SRGUT) was designed to test the annular plate of above ground storage tanks (AST’s) while the tank remains in service.

The technique is based on the concept of pulsing guided laminar waves into the base material from the chime area. The waves propagate up to three feet into the annular plate. When corrosion, pitting, erosion are present the ultrasonic waves mode convert and are received by the same transducer.

The technique is also being used to test for corrosion under pipe supports, corrosion at soil air interfaces, and similar difficult to access locations.

• high probability of detection.
• The waves propagate up to three feet into the annular plate.
• for screening corrosion, erosion and pitting.
• used for screening of locations under support in pipelines.

The technique produce A-scan, C-scan for scanned area showing defected areas color coded.

• Tank Floor Annular Plate Testing
• Testing Concrete Coated Interfaces
• Testing Under Pipe Supports
• Tank Dyke Piping Interfaces
• Scan Under Vessel Supports
