Real time radiography (RTR) for corrosion investigation is an excellent screening tool designed to detect Corrosion Under Insulation (CUI). The low-energy Xray source and hand-held detector provide instant imagery of the surface profile of piping under insulation. When corrosion is detected, further investigation can be planned and performed based on the information provided. Due to the speed, small footprint, and the ability to provide focused information, RTR can provide substantial cost savings to our clients by preventing unneeded insulation removal. Small two-man RTR crews can access suspected (CUI) areas of facilities quickly and efficiently, allowing clients plenty of time to develop further prove-up inspection and equipment repair.
