QSR® System

The QSR® System is a guided wave inspection platform designed for scanning in‑service assets at locations hidden from direct access.

It generates a remaining wall thickness profile of the scanned section, supporting integrity decisions based on measured condition in areas where other technologies provide only qualitative assessment.

EMAT (Electro‑Magnetic Acoustic Transducer) based sensors are used to induce guided waves in the asset without direct contact, enabling smooth movement without risk of damage and accurate measurements over rough surfaces, while minimising surface preparation.

To address different access constraints and geometries, two scanning approaches are available: Circumferential and Axial propagation.

System components

  • QSR® ePOD: common electronics unit for all configurations, controlling acquisition and data transfer;;
  • Sensors: specially designed EMAT based sensors that generate and receive guided waves, with distinct sensor designs for circumferential or axial propagation;
  • Frames: position and maintain the sensors on the pipe, adapting to diameter and inspection geometry;
  • Motors: enable controlled, repeatable scanning steps for accurate profile acquisition;
  • WaveProQSR: software for system control, structured data presentation, and reporting.

System settings can be adjusted to suit different applications, balancing coverage, resolution, and inspection speed.

Circumferential Configuration

Guided waves propagate around the pipe circumference, while the system advances in controlled axial steps. Measurements are captured at each position and combined to form a thickness profile along the scanned pipe length.

Best suited for:

  • Unwelded simple supports
  • Unwelded saddle supports
  • Scab patches

Scanning is performed using dedicated Sensor Carts designed for circumferential propagation. The primary system is the QSR1®, a self‑contained scanner built for efficient inspection of exposed pipe sections.

Axial Configuration

Guided waves propagate along the pipe axis while the system moves around the pipe circumference, measuring the area ahead of the sensor at each step. The results are combined to build a thickness profile along the circumference of the scanned section.

Best suited for:

  • Clamped supports
  • Earth/Wall penetrations
  • Embedded sections
  • Vertical pipes

Scanning is performed using a low‑profile Axial Sensor and a Traction Unit. The primary system is the QSR® Axial, designed for inspection from the side of the feature, where access is limited to a lateral approach.
