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.
|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|
|Corrosion detection without insulation removal||Accuracy +/- 10% CUI and 0.2%!! for corrosion monitoring|
|Object wall thickness range from 3 to 35mm||Focused probes (patent US 6,291,992)|
|Object insulation thickness up to 200mm||Cost benefits from the use of one set of equipment for many different locations and applications|
|Object temperature up to 500°C||Computed Control and Stand Alone operation mode|
|Pipe diameter larger than 3”||Robustness: No moving parts|
|Pulsed Eddy-Current Applications:|
|Corrosion Under Insulation - CUI||High temperature applications|
|Concrete fire proofing (spheres/skirts)||Heavy corroded equipment|
|Storage Tanks Annular Plates||Offshore risers and caissons|
|In-service Corrosion Monitoring||D-PEC The well inspection solution|
