The QSR1® is GUL’s new quantitative short range (QSR) device, incorporating the latest guided wave technology and hardware. The system is designed to semi automatically scan predefined sections of straight pipelines for corrosion under pipe supports (CUPS). The QSR1® can provide a quantitative measure of the average wall, as well as the remaining wall thickness down to half of the nominal wall thickess. The inspection system is designed to quantitatively inspect pipes for corrosion under pipe supports (CUPS).
