How Gas and Oil Pipeline Girth Welds Are Ultrasonically Tested

Pipelines transport huge volumes of gas and oil. Pipes are girth-welded on-site, typically using automated welding systems. For construction of pipelines, welds are the “weak spot” as this is where defects tend to occur. This video from CRC-Evans Pipeline International shows how pipe girth welds are nondestructively tested by automated ultrasonic test methods.
