Principal Benefits of Guided Waves • 100% coverage throughout the thickness of the structure.
• Inspection over long distances from a single probe position.
• Ability to inspect hidden and inaccessible regions of structures and structures under water, coatings, insulations, and concrete.
• Cost effectiveness because of inspection simplicity and speed.
Common Uses • Pipe inspection and monitoring
• Plate inspection and monitoring
• Delamination detection
