System RPTR

Unique about this testing system is the way to couple the ultrasound into the specimen. Water jet coupling is used, which means that the water path between probe and tube surface is in the order of several centimetres. This method of ultrasonic coupling results in little wear for the probes and the probe guiding devices. Also for a rough tube surface, stable coupling conditions are achieved because the water path can vary more than with gap coupling.
The ultrasonic testing system ECHOGRAPH RPTR is designed for rough environmental conditions and a high throughput. This system is especially suitable for an off-line inspection. It consists of a testing portal and several multi-probe holders. The tubes are typically loaded with a transverse conveyor. Once the tubes are placed in the testing portal, rollers put the tubes into rotation. The number of probe holders is chosen in accordance with the desired throughput and the respective testing task(s). The probe holders are linearly moved along the tube and inspect the tube in the 12 o’clock position. Rotational and translatory movements result in helical test traces.
