M-Skip Probe and Wedge Kit

M-Skip Ultrasonic transmit-receive probes and wedges for use either side of obstructions.

Multi-Skip or M-Skip probes and wedges offer an ultrasonic solution for corrosion detection of typically difficult to access areas of pipelines; around obstructions such as pipe supports, clamps and saddles.

M-Skip is an ultrasonic ‘transmit-receive’ method that locates probes and wedges either side of an obstruction. Ultrasound is transmitted through the wall of a pipeline or inspection surface, beneath the ex-ternal obstruction and is received on the far side. The ultrasonic waves ‘skip’ between the internal and external surfaces and the arrival times of the signals are used to calculate wall thickness. Corrosion is detected through loss of signal amplitude, reduced signal arrival times and changes to signal shape.
