Pulsed Eddy Current (PEC)

Pulsed Eddy Current (PEC)


Corrosion under insulation (CUI), corrosion under fireproofing (CUF) and their related complications are some of the costliest problems in the oil and gas industry. Corrosion demands an effective and efficient solution. This can be found in the Eddyfi's new Pulsed Eddy Current (PEC) using the LYFT system. Some of the benefits are as follows:

  • Increased inspection-time efficiency

  • Optimizes wall thickness and locates both OD and ID wall loss, without the need for costly insulation removal

  • PEC probes can scan up to 15 readings per second, based on insulation thickness and can scan through thick metal

  • System offers real-time C-scan imaging for quick anomaly overview reference and a user-friendly interface, which removes operator-specific dependence with SmartPULSE™ technology

    • SmartPULSE™ optimizes WT measurements, ensuring enhanced performance and repeatability without requiring advanced knowledge of the technology.

    • PEC is built for durability, weighing only 14 pounds, and cools itself without external air exchange.

    • PEC utilizing the LYFT system locates and identifies integrity issues and creating a corrosion map within a given footprint of refining and petrochemical insulated equipment without removing insulation.

This system is even more effective when used in accordance with Atlas Inspections’ own inspection criteria, in which each process system’s variables are taken into consideration when applying an inspection plan for CUI. The PEC technique coupled with Atlas Inspection’s approach to developing precise, equipment variable driven inspection plans, has changed the mindset of how CUI and CUF is managed and inspected while supplying each plant manager and their staff valuable data for what was previously an extremely tough phenomenon to control and predict.
