DRY-COUPLED PERMANENTLY INSTALLED ULTRASONIC SENSOR LINEAR ARRAY

摘要

This invention relates to permanent, ultrasonic, flexible, dry-coupled, linear arrays for the inspection of pipelines, process equipment: and the like. The permanent, ultrasonic, flexible, dry-coupled, linear arrays detect and/or measure corrosion wali loss, stress corrosion cracking, and/or interna! initiated pipeline cracking. The apparatus for ultrasonically testing materials includes a linear array of ultrasonic sensors, and a flexible, acoustically transmissive, dry-coupling surrounding at least a portion of each of the ultrasonic sensors.
