Axial QSR®

Axial QSR® is the extension of the QSR1® concept to cover those cases when we need to scan the pipe from a different direction than QSR1®. The Axial QSR® scanner is a low-profile device to fit snugly into tight spaces near pipe supports and in pipe racks, and moves circumferentially around the pipe.
Axial QSR® also uses EMAT technology to send and receive short-range guided waves and uses patented wide frequency and wavelength technology.

How does it work?

At each of the scanned circumferential position, the Axial QSR® transmitter sensor generates shear horizontal (SH) guided waves, which propagates in the pipe axial direction, and is received by the receiver sensor. The two main measurement results include the average wall thicknesses directly under the sensor, and the minimum remaining wall thicknesses within 5- 50 cm in front of the sensor, denoted by A and D1 respectively. The Axial QSR® data collection and scan configurations, including the total circumferential scan length, is controlled using the WaveProQSRTM software installed on a Windows computer.
