Description
A wedge for installations that cannot be cooled down. It withstands 260°C, so a pipeline, vessel or boiler is inspected while running, with no shutdown and no waiting for it to cool. The contact time per placement comes from the procedure — the wedge takes the heat rather than holding it off indefinitely.
Features
- Rated to 260°C
- 55° refraction, shear wave
- Water feed and scanner yoke mounting points
- DP28 housing, 64 × 44 × 34 mm
