By bringing a semiautomated phased array solution into the corrosion inspection market, Olympus has not only introduced a new technology, but also a new world of possibilities. Say goodbye to unsafe and unreliable motorized rastering of small UT probes; phased array probes cover a larger surface, and can be manually traveled at a safe speed. This solution enables inspectors to be more productive and collect higher resolution data.
The HydroFORM™ and RexoFORM™ are designed to offer the best inspection solution for the detection of wall-thickness reductions due to corrosion, abrasion, and erosion. Our solution also detects mid-wall damage such as hydrogen-induced blistering or manufacturing-induced laminations, and easily differentiate these anomalies from loss of wall thickness.
The unique quick adjustment device offered by both scanners allows the wedge/probe assembly to be positioned to any curvature greater than 4 in. OD (101 mm).
HydroFORM
High-performance corrosion mapping for rough and uneven surfaces
- Easy gate synchronization with the front wall for OD and ID corrosion monitoring.
- Wedge reflection is eliminated.
- Coupling is optimized.
- Provides excellent near-surface resolution.
HydroFORM utilizes an ingenious water-column concept that eliminates the need for a wedge, thus providing the benefits of a phased array immersion-tank inspection. This concept, which uses a low-flow water supply and consumable gaskets, offers excellent surface conformance and optimized coupling conditions, even on rough surfaces.
By exploiting gate synchronization with the interface echo available in the OmniScan® software, the HydroFORM provides optimum near-surface resolution, precision measurements, and an enormous improvement in flaw characterization over conventional UT.
