Solid Rings

The solid transducer rings are typically used for standard screening of pipes with a nominal size between 2 and 8 inches in diameter. The rings are attached to the pipe by tightening the two large handles which push the spring loaded transducers onto the pipe to obtain good shear coupling.

Standard rings have 2 rows of transducers to transmit torsional wave modes. Customised rings can be specially produced in other sizes or with 4 rows of transducers to allow for inspection using both longitudinal and torsional guided wave modes.

The solid rings work with all versions of the Wavemaker® and are available in either a LITE version or a High Temperature (HT) version.

Key application areas include:

  • Bare / Painted Pipes
  • Sleeved / Unsleeved Road Crossing Pipes
  • Buried Pipes
