Sustained-load cracking – why is it necessary to have my 6351-alloy cylinder inspected with an eddy-current device?
- When properly used, eddy-current devices contribute significantly to early detection of hard-to-see sustained-load cracks. However, an eddy-current test is not a replacement for a diligent visual inspection by a properly trained inspector.
- Eddy-current devices are tools to enhance proper visual inspections.
- Eddy-current devices currently approved by Luxfer for use with Luxfer 6351-alloy cylinders are Visual Plus, Visual Plus II, Visual Plus III, and Visual Eddy. However, the only eddy-current device approved by Luxfer for use with cylinders made from Luxfer’s proprietary 6061 alloy is Visual Plus III.
