Page 3: Purpose
PEC Flaw Detector PE4332 Operation Manual PURPOSE The Pulsed Eddy Current Flaw Detector PE4332 (PEC Flaw Detector PE4332) is designed to detect corrosion under insulation without removal of the latter. The Device is used to inspect such items as: Insulated pipelines including pipelines in operation: Figure 1. - Page 4 PEC Flaw Detector PE4332 Operation Manual LNG tank supports: Figure 4. LNG tanks. Ship hulls with thick paint or epoxy coating: Figure 5. Ship hull. The Device allows testing such items without preliminary surface preparation or insulation removal. The insulation can be represented with any non-conducting coating, such as polyurethane, mineral wool, plastics, paint, or air.

Page 44: Device Operation
DEVICE OPERATION The PEC Flaw Detector PE4332 can operate in two modes. They are the simple mode of thickness measurements and the scan mode. The scan mode is used when it is necessary to test any expanded area of the test item. - Page 45 PEC Flaw Detector PE4332 Operation Manual Figure 43. Diagram for sensor selection, for aluminum casing or for option without casing Figure 44. Diagram for sensor selection, for tin casing. The larger is the thickness range and insulation thickness range, the larger is the sensor.
- Page 46 PEC Flaw Detector PE4332 Operation Manual the larger is the sensor, the larger is the area over which the averaging takes place and, accordingly, the larger is the minimum fault that the device can detect. Therefore, it is advisable to use as small sensor as possible.

Page 50: Scan Mode
Any thickness measurement to be carried out with PE4332 is performed relative to the known thickness in a certain point of the test item. Therefore, prior to the thickness measurements, it is necessary to calibrate the Device for this test item. - Page 51 The example of such grid is shown in Figure 50. Figure 50. Example of self-adhesive grid produced by Oktanta. You can manually draw the grid on the test item using a ruler and a marker, however, we do not recommend this method as it requires a lot of time.
