HD Inflatable Rings

The HD inflatable ring has been developed for the same applications as the HD solid ring where higher sensitivity and resolution are required, and pipe sizes are larger than 6 inches.

When mounted with HD transducers, the use of this type of ring requires the Wavemaker® G4mini or the Wavemaker® G4 with the medium frequency option (LF+MF option).

HD

2-row fixed space transducer modules with four transducers per module to inspect at a high frequency range. Key application areas include:

• Bare / Painted Pipes
• Sleeved or Unsleeved Road Crossing Pipes
• Pipes with many welded supports
• Concrete Anchor Supports
• Inspections for Localised Pitting

Adjustable

The 2-row adjustable transducer modules with four transducer spacings described in the EFC Inflatable Rings page can also be mounted in the HD Inflatable Rings to cover a wider range of applications:, for example:

• Buried Pipes
• Pipes with general corrosion
