Pressure vessels are closed containers designed to hold fluids at pressures substantially different from the ambient pressure. These vessels are ubiquitous in refineries. Due to the critical nature of their function, pressure vessels must undergo regular and rigorous safety testing. Find out more at www.eddyfi.com

Keeping Pressure Vessels Safe with the Sharck™ Probe
- 1. Keeping Pressure Vessels Safe with the Sharck Probe Application Note
- 2. The Challenge Refinery pressure vessels are subjected to the harshest conditions around • Carbon steel welds are critical components prone to several cracking mechanisms in different zones (toe, cap, HAZ) In this application welds are often controlled with wet magnetic particle testing (MT). • This type of magnetic particle testing uses particles suspended in a water or oil solution. The particles can also be fluorescent to take advantage of the eye’s sensitivity to color. 2 © Eddyfi NDT Inc. 2009–2016
- 3. The Challenge Wet MT is: • Messy • Requires surface preparation • Requires post-inspection cleaning • Requires repainting or recoating weld, • Time consuming • Unable to measure defect depth • Unable to archive data Any surface-breaking defects in pressure vessel carbon steel welds are target defects. 3 © Eddyfi NDT Inc. 2009–2016
- 4. The Solution The patent-pending Sharck™ probe was designed specifically for this type of application. • Spring-loaded fingers designed to adapt to geometry of weld crown • Enables scanning cap, toe, and HAZ in single pass • Built-in encoder to precisely position defects along welds 4 © Eddyfi NDT Inc. 2009–2016
- 5. The Solution Unlike wet MT, the tangential ECA (TECA™) technology incorporated into Sharck probe can: • Size length and depth of cracks • Without surface preparation • Designed to monitor (as opposed to cancelling it out) and compensate for liftoff Sharck is also designed to • Scan at speeds up to 200 mm/s (8 in/s) • Record inspection data • Display data as intuitive 2D/3D C-scans 5 © Eddyfi NDT Inc. 2009–2016
- 6. The Solution 6 © Eddyfi NDT Inc. 2009–2016 Under actual conditions, Sharck detected and measured cracking in cap and toe of abrasive-blasted welds 12.7 mm (½ in) thick. • Cracks presence confirmed with wet MT • Sharck probe also detected transverse cracks Longitudinal crack approx. 6 mm (0.25 in) deep, 78 mm (3 in) long Transverse crack
- 7. The Benefits Solution has following benefits: • Productivity gains — No need for surface preparation or post-inspection cleaning. • Increased PoD — Detect previously undiscovered defects and size them. • Better reliability — Single-pass scanning with intuitive C-scan imaging. • Accountability — Full data archives to keep track of defect evolution. 7 © Eddyfi NDT Inc. 2009–2016
