HT solid rings are milled from aluminium and can be used on pipes up to 350°C (660°F) if the correct procedures are followed.

Solid 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.

HT solid rings work with all versions of the Wavemaker®.

Key application areas include:

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