Ultrasonic In-Line Inspection is using an ultrasonic echo signal to measure the pipe wall thickness, detecting any variations from the nominal values.
In intelligent pigging applications, these high-frequency radial signals are emitted by UT transducers perpendicularly to a pipe wall. These signals produce two significant echoes – from the inner surface and the outer surface of a pipe wall. We detect the anomalies through the registered difference between periods of receiving the echo signals from a healthy pipe (nominal values) and pipe wall with metal loss or any inhomogeneity.
PIPECARE ultrasonic metal loss inspection tools work based on the direct measurement principle to ensure quantitative wall thickness measurements, superior detection, and sizing of metal loss anomalies, laminations, and inclusions.
