Thickness and Flaw Inspection Solutions

HydroFORM Scanner

An easy-to-deploy 2-axis encoding phased array (PA) solution, the semiautomated HydroFORM scanner enables fast and reliable wall-thickness mapping and midwall damage detection by acquiring high-resolution data of large surfaces in minimal time. While the standard HydroFORM package comes equipped with the proven phased array linear probe and local immersion system, you can now choose for a dual array probe configuration. Both options allow for a resolution of up to 1 mm × 1mm.

To optimize the productivity of raster scanning, the HydroFORM system is equipped with several efficiency-boosting features:

• Integrated X and Y axis encoders
• Smart indexing button
• Index position and coupling indicators
• Scan speed check
• Efficient bubble management (with I8 linear probe)
• Easy-to-index magnetic wheels (with REX2 DLA probe)
• Braking system

Easily adapting to curvatures 4 in. OD (101 mm) and greater, this PA solution facilitates a wide range of applications including:

• Monitoring wall-thickness reductions due to corrosion, abrasion, and erosion
• Detecting midfall damage, such as hydrogen-induced blistering or manufacturing-induced lamination, and differentiating these anomalies from loss of wall thickness

HydroFORM Polymer System: Corrosion Mapping Beyond Water-Coupled Inspections

The HydroFORM polymer system expands the inspection range of the HydroFORM scanner by replacing the traditional water delay line with a specially engineered polymer delay line. This innovative option enables reliable corrosion mapping in temperature conditions and inspection environments where maintaining a water delay line is difficult, impractical, or impossible.

Built on the proven performance and ease of use of the HydroFORM scanner, the polymer system is available in two specialized formulations optimized for either high-temperature or low-temperature inspections, extending the operating range of HydroFORM from −20 °C to 175 °C (−4 °F to 347 °F).

Innovative Polymer Delay Line Technology

The HydroFORM polymer system combines a high-performance polymer delay line with a protective membrane to deliver reliable ultrasonic performance while overcoming many of the traditional limitations associated with polymer-based delay lines.

While the polymer delay line has been carefully selected to provide optimal acoustic performance, the protective membrane helps ensure consistent coupling and acts as a protective barrier that prevents direct contact between the polymer and the inspection surface. This design eliminates the risk of the polymer sticking to or wearing against the surface during scanning, improving both durability and ease of operation.

Low-Temperature Inspections Down to −20 °C (−4 °F)

Water-based delay lines are also limited in cold environments where freezing prevents reliable operation.

To address this challenge, Evident is using a dedicated low-temperature polymer with optimized acoustic properties designed specifically for cold-service inspections. This configuration allows to perform inspections from −20°C (−4°F) to 50°C (122°F). Effortless High-Resolution

ScanDeck™ Module

The ScanDeck module is like your scanning dashboard, situated directly in your eyeline while you operate the HydroFORM scanner. Using a combined HydroFORM and OmniScan™ X4 solution, you fully benefit from all the functionalities of the ScanDeck module.
