Scanning Systems

GUL’s proprietary QSR® Scanning Technology is specifically designed to quantitatively measure the remaining wall thickness profiles of corroded areas under pipe supports – not easily accessible or hidden from direct access.  We offer two different scanning devices for this purpose

  • QSR1® scans pipelines in the axial direction using circumferential guided waves;
  • Axial QSR® scans pipelines circumferentially using axial guided waves.

The devices complement each other by scanning and measuring defective areas in circumferential and axial directions.

QSR1 scanning to size corrosion at a pipe support

Quantitative measurements that are accurate and reliable

The QSR system utilises GUL’s patented quantitative short range technology for corrosion sizing applications.

The defect measurement capabilities of the QSR1® and Axial QSR® are complimentary. For simple supports where defects are typically extended axially and access to the top of the pipe is unrestricted the QSR1® provides a well proven method of measurement where both transmission through and reflection from areas of wall loss are used to provide reliable and accurate wall measurements.

Axial QSR® is able to provide wall measurement from areas QSR1® is unable to access for reasons such as pipe diameter and constraints to access. Our sales experts will be happy to advise you for the specifics of your application.
