HT Inflatable Rings

High Temperature (HT) Inflatable Rings and modules have EFC performance with the added capability of testing pipes operating at up to 350°C, provided that the ring is removed from the pipe within 15 minutes of being applied.

In order to carry out the guided wave inspection, only a 50-cm (20-inch) wide strip of insulation needs to be removed. No couplant is required.
