PI-Scan ultrasonic testing for multi orientated imperfections (oblique angle)

PI-Scan

An Ultrasonic testing system for the detection of imperfections oriented at any angle to the major axes of tubular products. The standard Unicorn Rotary Probes are generally used to detect longitudinal and transversely oriented imperfections. Some tube/pipe users however are concerned about the possible incidence of imperfections lying at intermediate orientations to the longitudinal and transverse directions which would not normally be detectable with the standard inspection methods. .
Unicorn have developed the Pi-Scan system specifically to satisfy this requirement. The comprehensive inspection is accomplished by rotating (at very high speed) a cluster of transducers in a contact shoe mating on the tube surface. Full length inspection can be carried out either by spiralling the tube past a fixed inspection station or traversing the spinning device along a fixed rotating tube



Reasonable inspection times (6 minutes per pipe) can be achieved by using multiples of the spinning inspection head on the same site.
