NDT – Pulsed – Eddy-Current Inspection

PEC is the cost effective corrosion detection and monitoring solution of TÜV Rheinland.

Assessing condition of pipework and pressure vessels under insulation can be advantageous to plant operators. The PEC system was developed by TÜV Rheinland in partnership with Shell Global Solutions as a technique to the detection of corrosion under insulation (CUI). It is now available at TÜV Rheinland to all markets worldwide.

Compared with conventional eddy-current testing, Pulsed- Eddy-Current inspection does not require direct contact with the object being tested. Measurements can be made through any non-magnetic and electric conductive insulation material including coatings, rockwool, foam glass, wrapping layers, weather-proofing sheetings and even corrosion products.

PEC is further effective in high temperature non-destructive testing (NDT) inspections.

Pulsed Eddy Current (PEC) - Working Principles

Benefits of Our Pulsed Eddy-Current Inspection Services at a Glance
PEC is a non-intrusive electromagnetic technique based on Pulsed Eddy Current
No direct surface contact and preparation is needed
It allows corrosion measurements in low alloyed carbon steel pipes and vessels through their insulations, coatings, paints, concrete fire-proofing, marine growth
No costly and unnecessary insulation removal is needed to perform the examination with a considerable cost saving for the client
PEC Advantages:
Corrosion detection without insulation removalAccuracy +/- 10% CUI and 0.2%!! for corrosion monitoring
Object wall thickness range from 3 to 35mmFocused probes (patent US 6,291,992)
Object insulation thickness up to 200mmCost benefits from the use of one set of equipment for many different locations and applications
Object temperature up to 500°CComputed Control and Stand Alone operation mode
Pipe diameter larger than 3”Robustness: No moving parts
Pulsed Eddy-Current Applications:
Corrosion Under Insulation - CUIHigh temperature applications
Concrete fire proofing (spheres/skirts)Heavy corroded equipment
Storage Tanks Annular PlatesOffshore risers and caissons
In-service Corrosion MonitoringD-PEC The well inspection solution
