Phased Array Ultrasonics (PAUT)Amine Service Cracking in Heat-Affected Zone
This image from Phased Array Ultrasonic Testing (PAUT) showcases the detection of amine service cracking in the heat-affected zone (HAZ) adjacent to a weld. Unlike common weld cracks, these are specifically due to the corrosive effects of amine solutions in the HAZ. The PAUT image reveals linear indications characteristic of stress corrosion cracking that occurs in environments involving amine-based chemicals. This type of cracking is particularly concerning because it can compromise the integrity of the structure in areas not typically subjected to the same scrutiny as welds themselves. This finding highlights the importance of inspecting the HAZ in amine service environments for early detection and prevention of such defects.
