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).

RexoFORM

Quick and easy corrosion mapping for smooth surfaces and limited access areas

Smaller, lighter, and perfect for limited access areas (rope access).
Excellent surface coverage.
Operates without the need for a continuous water supply.
Affordable complement to the HydroFORM.

The RexoFORM is a new innovative wedge for phased array 0º and angle beam inspection with the Rexolite delay line. With its unique design, the RexoFORM can be used on pipes of different diameters with no need for multiple curved wedges. The RexoFORM is also compatible with the A12 and A14 standard probes, making it an affordable solution.

The RexoFORM is the perfect complement to the HydroFORM. In fact, it is simple, small, and easy to use, even when a continuous water supply is not available, and/or in limited access areas. The RexoFORM is also compatible with Olympus scanners such as the Mini-Wheel, the VersaMOUSE, the CHAIN Scanner, and the GLIDER scanner, to name a few.

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.
