Acoustic mapping finds defects on tube, pipe ID

摘要

For the past few decades, acoustic microimaging (AMI) tools have proven useful in finding and mapping features in the bond zone between a small-diameter tube or pipe and the large-diameter tube or pipe into which it has been inserted and bonded. The purpose is usually to look for gap-type defects, such as voids, delaminations, and nonbonded areas, between the small tube's ID and the large tube's OD (see Figure 1). This application is a nondestructive method that finds types of structural anomalies, meaning that no cutting or grinding processes are necessary.
