Rapid Long-Range Pipe Screening with GWUT
Guided wave ultrasonic testing (GWUT) is a highly effective NDT and Inspection service for screening corrosion in insulated, buried, or otherwise inaccessible piping. This advanced technique has become a preferred method for inspecting large piping segments due to its efficiency and ability to detect anomalies that can be further evaluated using quantitative NDT methods.
Key Benefits of Guided Wave Ultrasonic Testing (GWUT)
- Screens extensive piping segments for internal and external corrosion in just minutes from a single access point
- Detects anomalies in piping, enabling targeted follow-up inspections to assess severity
- Locates girth welds on insulated piping circuits for further inspection or maintenance
Primary Applications of GWUT
- Insulated piping
- Buried piping
- Pipeline road crossings
Under optimal conditions, GWUT can screen many feet of piping quickly and efficiently, making it an invaluable tool for maintaining pipeline integrity. By providing reliable data on corrosion and other anomalies, guided wave ultrasonic testing supports compliance with ASME Code requirements and enhances the safety and reliability of piping and vessel fabrication facilities.
