6.2 Wedge Pipe Diameter Ranges
The FlexoFORM scanner’s wedges have predefined curvatures according to the
Nominal Pipe Size (NPS) standard. Although it is recommended to use a wedge that
matches the exact diameter of the inspected pipe, each wedge has a narrow range of
pipe diameters on which it can be used. Table 7 on page 59 provides the range of
coverage for each standard wedge diameter.
