Pulsed Eddy Current (PEC)

Pulsed Eddy Current (PEC)


Automated Software for Reliable and Repeatable Results 

The Lyft software is packed with automation and advanced algorithms that remove operator-specific dependence, thanks to the power of the SmartPULSE™ technology. It automatically optimizes pulser and receiver parameters (gain, duration, time gates, filters, etc.). SmartPULSE also optimizes wall thickness (WT) measurements, which ensures optimum performance and repeatability, while limiting the need for advanced knowledge of pulsed eddy current. The multi-touch, user-friendly software also includes several innovative features, including real-time C-scan imaging (grid-mapping and dynamic modes), complete wall thickness measurements (ID and OD corrosion), as well as complete inspection management and reporting capabilities.


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 Inspection Technologies’ 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.
