... version of CSA Z662 includes both a depth and a sharpness criteria (i.e. length to depth ratio). For the dents reported by inline inspection (ILI) that exceed either the dent depth or sharpness criteria, a pipe wall curvature strain-based assessment can be completed to determine their acceptability based...
