Sigma provides ASNT/CSWIP/PCN Level I, II, & III technicians for Automated UT Corrosion Mapping (AUT) to detect anomalies (flaws) and metal loss (corrosion/erosion) in welds, metal pipe, vessels, and metal floor/wall sheets.

AUT is an NDT/NDE discipline widely used in the oil and gas industries for the in-service detection and characterization of corrosion/erosion in pipes, vessels, and storage tanks. AUT maps metal thickness using ultrasonic waves to identify variations in metal thickness due to corrosion/erosion. The variations can be graphically displayed and stored as a digital image.

Certified technicians are available for call-out or long-term assignments. Sigma provides turnkey AUT inspection and reporting complete with equipment, consumables, vehicles (mileage), and accommodations required to perform Corrosion Mapping.
