Ultrasonic system for oblique multi-angle testing UNICORN Automation supplies rotary heads for ultrasonic inspection of seamless or welded hot finished tubes using the contact shoe method of testing. These test systems generally inspect for longitudinal and transverse orientated defects and occasionally can be equipped for discrete oblique angles. Oblique multi-angle testing is being requested more regularly by both tube manufacturers and pipe users. To address this move towards multi-oblique angle testing, Unicorn has developed a test system known as ‘Pi-Scan’.

This ultrasonic test system is intended for the detection of imperfections orientated at any angle to the major axis of tubular products. The comprehensive inspection is accomplished by rotating, at very high speed, a cluster of transducers in a contact shoe mating with the tube surface. An all angle shear wave inspection will enable manufacturers and third parties to offer customers a more comprehensively tested product.

Full tube length inspections can be carried out either by spiralling the tube past a fixed station or traversing the spinning device along a fixed rotating tube. In addition to full-length pipe inspection, the system can be used for applications such as pipe end testing, bar testing or plate inspection. Pi-Scan can be supplied as a new system or
