Abstract
An ultrasonic probe apparatus for detecting flaws in a tubular includes a probe housing. The probe housing has an axial axis, a central cavity lying along the axial axis, and a bottom face adapted for placement on the tubular. The bottom face of the probe housing has an opening in the middle. A probe support is disposed within the central cavity and rotatable about the axial axis of the probe housing. An ultrasonic probe is mounted on the probe support and has a scanning face exposed to the opening of the bottom face of the probe housing, and may be coupled to the pipe with a liquid acoustic couplant medium.
