    Together with Lyft 1.3, the new patent-pending PEC-GS probe allows for in-service inspection of insulated structures protected with galvanized steel weather jackets, such as those found in refineries in many countries. The solution combines all the existing features from previous versions, such as the compensated wall thickness (CWT) tool, noise immunity, SmartPULSE™, and more.

    Designed to overcome the adverse effects known to galvanized steel cladding, the patent-pending probe ensures:

    • Improved signal penetration
    • Excellent detection capabilities and sizing accuracy
    • Enhanced signal-to-noise ratio (SNR)

    This webinar, hosted by Andreanne Potvin, product manager, and Vincent Demers-Carpentier, R&D engineer, covers the following:

    • Pulsed eddy current (PEC) working principles

    PEC Reinvented—CUI Programs Redefined

    Corrosion under insulation (CUI) is possibly the greatest unresolved asset integrity problem in the industry. Current methods for measuring wall thickness over insulation (liftoff) without removing it all have severe limitations. Now, Eddyfi introduces Lyft — a high-performance reinvented pulsed eddy current (PEC) solution. This patent-pending system features a portable, state-of-the-art instrument, real-time C-scan imaging, fast data acquisition (up to 15 readings per second) with grid-mapping and dynamic scanning modes, and flexibility with long cables and an extension pole. The Lyft standard probes can also scan through thick metal and insulation, as well as aluminum, stainless steel, and, unique to Lyft, galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs. Got Lyft?

    Lyft is offered in two models: the powerful GD model capable of dynamic and grid mapping, and a lighter G model offering conventional grid mapping only.

    Automated Software for Reliable and Repeatable Results 

    The Lyft software is packed with automation and advanced algorithms that remove operator-specific dependence, thanks to the power of the SmartPULSE technology. It automatically optimizes pulser and receiver parameters (gain, duration, time gates, filters, etc.). SmartPULSE also optimizes wall thickness (WT) measurements, which ensures optimum performance and repeatability, while limiting the need for advanced knowledge of pulsed eddy current. The multi-touch, user-friendly software also includes several innovative features, including real-time C-scan imaging (grid-mapping and dynamic modes), complete wall thickness measurements (ID and OD corrosion), as well as complete inspection management and reporting capabilities.

    Unique to Lyft—Wall Thickness Measurement Tool for Smaller Flaws

    Under sizing is a well-known phenomenon for PEC where defects smaller than the probe’s averaging area appear shallower than they really are. The Lyft’s compensated wall thickness (CWT) tool mitigates this phenomenon by quantifying the minimum wall thickness of a specific region in a C-scan. The CWT tool’s specialized algorithms isolate a defect’s contribution to the A-scan signal to more precisely compute its minimum wall thickness.

    Desktop Analysis Software

    Lyft Pro enables advanced Lyft data analysis and features the same graphical user interface than the Lyft software, making it easy to learn and benefiting from larger data layouts. This translates into Lyft instruments out in the field acquiring data while analysts work hard to extract value from acquired data. Lyft Pro makes it easier to plan inspections for several Lyft instruments. The software also has features to generate richer reports and tools to bridge calibration parameters between scan zones. Available for free to subscribing Lyft software and service plan users. Download Lyft Pro here.

    SurfacePro 3D is an advanced visualization and reporting software designed to automatically create components and overlay stitched C-scan data. Use it to Import Lyft reports, create 3D components, and stitch color maps automatically. Easily import, export, create, and edit report templates. Compile and merge inspection data with associated images, inspection parameters, and defect tables for fast and compelling reporting. Download SurfacePro here.

    Optimized Performance for Wall Thickness and Liftoff

    The Lyft solution includes three standard probes of different sizes for the right balance between wall thickness and liftoff. The probe family allows enough flexibility to support metal up to 102 mm (4 in) thick, insulation up to 305 mm (12 in) thick (fiber glass, plastic wrap, concrete, or other non-ferrous materials), as well as stainless steel, aluminum, and, unique to Lyft, galvanized steel weather jackets.  It is possible to scan through thicker pipe walls and insulation—inquire for details. The probes can also inspect hard-to-reach areas of various geometries, as well as scan walls and pipes as small as 25 mm (1 in) in diameter.

    Standard probes have a keypad for easy remote operation and can be equipped with a universal clip-on encoder enabling dynamic scans. Accessories include an extension pole (up to 4.6 m / 15 ft), extension cables (15 m and 30 m / 50 ft and 100 ft) for rope access, clip-on ergonomic handles and stabilizer, as well as probe shoes to operate on surfaces as hot as 120°C (248°F) and to attenuate vibrations in galvanized steel weather jackets.

    Application-Specific Probes

    The tank floor probe enables the in-service inspection of storage tank annular rings. With its 4.8 mm (0.2 in) thick, super-thin titanium blade, the probe can slide up to 400 mm (16 in) under tank floor edges, assessing the remaining wall thickness of this critical region exposed to corrosion. The embedded remote controls and status LEDs are also perfect for one-person operation.

    The splash zone probe can tackle offshore applications, thanks to its rugged design, watertightness to 15 m (49 ft) in grid-mapping mode, and 25 m (82 ft) heavy-duty cable. The splash zone probe is flexible enough to support metal up to 76 mm (3 in) thick and insulation or marine growth up to 203 mm (8 in) thick.

    The patent-pending galvanized steel cladding probe (PEC-GS) is specifically designed to improve detection capabilities and sizing accuracy by reducing the footprint dimensions to normal. The design neutralizes the interference from the jacket, improving signal penetration, and prevents vibration for an unsurpassed signal-to-noise ratio.

    Underwater probes can tackle deeper offshore applications. They are watertight down to 100 m (330 ft) and, through the long extension cable, are used with Lyft in grid-mapping mode. The embedded status LEDs ensure better control and synchronisation with the topside team. The probes can be used on metal as thick as 100 mm (4 in), as well as insulation and marine growth as thick as 300 mm (12 in).

    The Best of PEC in a Portable Instrument

    The Lyft instrument is sealed and designed for IP65. Its magnesium alloy casing is tough, water and dust resistant, and cools without any external air exchange. The adjustable stand, the top handle, and four corner anchor points make it practical for on-site inspections. The embedded and portable Windows® PC offers standard connect-anywhere capabilities and advanced productivity tools that optimize field testing. The premium-quality 26.4 cm (10.4 in) LED display is optically bonded, non-reflective, comes with 3 mm (1/8 in) strengthened glass, and is designed for gloved hands, under any lighting conditions. The system also comes with two, hot-swappable batteries for extended battery operation.

    Global NDT Equipment New Product Innovation Award Recipient

    For its dedication to creating a power-packed product that solves one of the major challenges across industries, testing for corrosion under insulation, Frost & Sullivan presented Eddyfi with the 2016 Global Nondestructive Testing Equipment New Product Innovation Award. “Eddyfi has done away with the dependence on operators by packing Lyft with its SmartPULSE technology, wherein the system automatically iterates to find the best parameters for the inspection configuration,” said Frost & Sullivan Principal Lead Nikhil Jain. “Using an autoset feature, the probe can find the optimal configuration for measurements and repeatability, adjusting the pulse frequency, gains, and other parameters.”
