The High Definition (HD) solid ring has been developed to utilise the high-frequency range available with the Wavemaker® G4 (with MF Option) and G4mini for applications where higher sensitivity and resolution are required on small diameter pipes. Such applications typically include interface penetrations, supports and localised pitting.

GUL Rings: HD Solid
GUL Transducer Ring: HD Solid
Available Models:
HD
Spring-loaded transducer ring for inspection of pipes with up to 6” diameter at a high frequency range. Key application areas include:
- Bare / Painted Pipes
- Sleeved / Unsleeved Road Crossing Pipes
- Buried Pipes
- Pipes with large numbers of welded supports
- Concrete Anchor Supports
- Inspections for Localised Pitting
