Pulsed Eddy Current (PEC)
Before pulsed eddy current (PEC), checking for corrosion under insulation (CUI) required removal of insulation which is cost prohibitive and time-consuming. Additionally, conventional NDT methods were limited to single points of inspection, unlike PEC.
Now, we have pulsed eddy current (the Lyft) by Eddyfi. This advanced NDT technique utilizes the principle of electromagnetic induction (which is not unlike conventional eddy current testing). Distortions in the eddy current indicate a flaw in the material, and pulsed eddy current can detect these flaws through insulation (unlike conventional eddy current testing). PEC does this by measuring the electromagnetic response to several frequencies simultaneously; which ultimately allows the technician to gather information from a range of depths (hence the use of PEC to detect corrosion under insulation).
Our utilization of pulsed eddy current (the Lyft) by Eddyfi certainly provides an advantage to alternative testing techniques and situation involving corrosion under insulation (CUI). The Lyft, which is Eddyfi’s pulsed eddy current flagship model, can detect erosion and corrosion through 6 inches of insulation at temperatures ranging from -240°F to 930°F. Furthermore, calibration of the system only requires around 30-45 seconds, which drastically reduces downtime. Now, the technology is impressive, but why should you choose us to handle it for you? Our focus for our technicians and the technology we implement is on training. We continually train technicians and match newcomers with seasoned eddy current veterans that have been in the field for 30+ years. This way, you can rest assured that the results you are receiving are accurate, and the work is done efficiently and promptly.
