PT Demonstration - reg

Dear Friends,

When performing Liquid Penetrant Examination demonstration, is it required to establish the maximum drying time after Surface Preparation (precleaning before penetrant application)?

If I fixed minimum drying time required after Surface preparation as 1 minute, is it required to repeat a demo for maximum drying time after surface preparation?

Yes you have to establish Minimum & Maximum drying time , Eg You wish to demonstrate Minimum one minute to Maximum 10 minute , Demonstrate one Minute drying time & 10 Minute drying time , It will cover 1 minute to 10 minutes drying time.

Lyft™: Pulsed Eddy Current Reinvented

PEC Reinvented—CUI Programs Redefined Corrosion under insulation (CUI) is possibly the greatest u
nresolved asset integrity problem in the industry. Current methods for measuring wall thickness with liftoff, without removing insulation, all have severe limitations. Eddyfi introduces Lyft — a reinvented, high-performance pulsed eddy current (PEC) solution. The patent- pending system features a state-of-the-art portable instrument, real- time C-scan imaging, fast data acquisition with grid-mapping and dynamic scanning modes, and flexibility with long cables. It 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. Got Lyft?
