LYFT

Eddyfi Lyft® – Flexible, Fast, and Reliable Corrosion Under Insulation (CUI) Integrity Management Solution.

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 galvanized steel weather jackets. Who else but Eddyfi to reinvent an eddy current technique and redefine CUI programs.

Benefits

• Inspect through thick insulation and fireproofing
• Save on insulation removal costs
• Real-time imaging for instant results
• Unrivalled productivity with PECA
• Easy setup with SmartPULSE™ calibration
• Highest confidence with Tau-scan™ and PermTool™ advanced analysis tools

Applications

• Corrosion Under Insulation (CUI) and Fireproofing (CUF)
• Insulated pipes and vessels
• Through aluminum, stainless steel, and galvanized steel weather jackets
• Safe, in-service scab corrosion assessment, no need to remove the scale
• In-service inspection of storage tank annular plates
• Underwater and splash zone structures
• Ship deck inspections through tiles and coatings

Optimized Performance for Wall Thickness and Liftoff

The Lyft solution includes several sizes of plug-and-play probes for the right balance between wall thickness and liftoff.

The PECA high-productivity probe is capable of a single-pass coverage of 457 mm (18 in) in grid or high-resolution encoded dynamic mode. It supports metal thickness 6–25 mm (0.25–1.0 in), insulation 0–102 mm (0–4 in), and stainless steel and aluminum weather jackets. CUI assessment has never been this fast, improving overall inspection productivity as much as 10 times.

The single-element PEC probe family supports metal thicknesses up to 100 mm (4 in), insulation as thick as 300 mm (12 in), and stainless steel/aluminium/galvanized steel weather jackets. They complement the array probes in limited-access, small-pipe, and thick-component inspections.

Application-Specific Probes

The patent-pending high-resolution PECA probe is designed specifically for the inspection of scabs and corrosion blisters. Using an array of dual sensors capable of spatial triangulation, the probe enables the detection of the smallest possible defects with PEC technology. It supports metal thickness 3–19 mm (0.12–0.75 in), insulation 0–50 mm (0–2 in) and a single-pass coverage of 75 mm (3 in) in dynamic or grid mode.

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 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.

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.
