Abstract

An ultrasonic probe apparatus for detecting flaws in a tubular includes a probe house. The probe house 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 house has an opening in the middle. A probe support is disposed within the central cavity and rotatable about the axial axis of the probe house. 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 house. The scanning face is tiltable relative to a selected plane of the tubular by rotation of the probe support about the axial axis of the probe house.
