For a pipe, enter the outside diameter. Axial scanning (probe moving along the pipe axis) keeps the flat-plate geometry in the scan plane; circumferential scanning follows the curvature, so the incident angle at the surface differs from the flat-plate value. The axial correction option chooses where the correction is applied: at the wedge base, at the intersection point, or not at all.
A wedge with a curved bottom face matches the pipe radius so the probe sits on the surface without a gap.
