Rapidly screen miles of piping from a single location to quickly identify areas of metal loss. The QSR 1 is an entry-level Guided Wave Testing (GWT) System, providing a fast screening method for inspecting long lengths of piping for corrosion. It uses low-frequency acoustic energy to check hundreds of feet of pipe from a single test location. The QSR 1 is valued for its portability and ease of use, making it an ideal tool for quickly prioritizing sections requiring detailed follow-up NDT in petrochemical plants and refineries. Supplier: Guided Ultrasonics Ltd. (GUL)
A portable and user-friendly Guided Wave Testing (GWT) system designed for rapid, long-range screening of pipework for corrosion. It sends guided ultrasonic waves down the pipe to detect corrosion and material loss up to hundreds of meters from a single test location. The system provides the solution of quick, 100% coverage screening for anomaly location on pipelines, drastically reducing inspection time and focusing detailed NDT efforts.
A system for Guided Wave Testing (GWT), used for long-range screening of pipelines and piping for corrosion and defects. Its main function is to identify areas of significant wall thickness loss for follow-up inspection.
| Principle | Long-Range Guided Wave Testing (GWT) |
| Application | Pipe screening for corrosion and erosion (typically 2 inch to 24 inch diameter) |
| Screening Range | Up to 100 m from a single location (bi-directionally), depends on pipe condition. |
| Frequency Range | Typically 10 kHz to 100 kHz (selectable for optimizing propagation) |
| Transducer Type | Magnetostrictive or Piezoelectric collar transducers (interchangeable for pipe sizes) |
| Data Analysis | Integrated software for A-scan display, distance amplitude correction (DAC), and focusing. |
| Portability | Field-portable unit (typically 5 kg to 10 kg for electronics) with AC/DC power options. |

GWT uses low-frequency ultrasonic waves to travel long distances (tens to hundreds of meters) along a pipeline to rapidly screen for large areas of corrosion or wall loss.
QSR likely stands for Quick Scan Ring or similar, indicating a system that uses an array of transducers clamped around the pipe to launch and receive the guided waves.
