In the example below, seven such indications were automatically tagged as SCC as they reached the predetermined detection threshold. The operator's detection threshold should always be adjusted based on the minimal size of defects that need to be detected. The default threshold for Spyne is 0.50V, but it can be adjusted to suit the inspection requirements. Each indication is automatically highlighted and marked with a yellow box and label.Īmong the surface-breaking indications are individual cracks, crack colonies, linear indications in the seam welds (DSAW, ERW, AO Smith, etc.), manufacturing defects such as mill scabs or weld splatters.Īll these indications are reported automatically by the software, based on a pre-defined signal threshold. The Spyne scan data is displayed as a 2D C-scan (axial position shown on the horizontal axis, and circumferential position on the vertical axis).
