1. Close Visual Inspection
A close visual inspection of the composite repair and surrounding steel surfaces details evidence of disbonding, delamination or further degradation such as rust staining. If any suspect regions are observed, a bond tester is used to ascertain if the layers of the composite repair are tightly adhered.
2. Ultrasonic Testing Wall Thickness Measurements
Ultrasonic Testing (UT) measures the nominal wall thickness of the piping or vessel adjacent to the composite repair. The ultrasonic measurement technique is an ultrasonic manual rapid scanning technique which provides accurate measurements of the nominal wall thickness. By measuring the nominal wall thickness, a remaining wall thickness can be calculated by subtracting the maximum pit depth.
3. Radiography is Used to Locate Defects
Radiographic imaging is used to identify areas of corrosion under the composite wrap. This information allows the precise targeting of BCT diagnostic imaging.
4. Accurate Pit Depth Measurement with BCT
Insight™ diagnostic imaging accurately gauges and visualizes defects in the steel host pipe of metallic pressure systems under composite wraps. The pit depth is subtracted from the nominal wall thickness for a remaining wall measurement.
