Any pipeline, pressure vessel, or a storage tank requires regular non-destructive testing using an ultrasonic thickness gauge, to inspect for corrosion. One way of doing this inspection, is to use a grid. Using a grid allows you to organize large area inspections, mark and identify areas of concern, and easily create corrosion reports. By redoing …

Surface contamination from soluble salts such as chloride, sulphate, or nitrate ions can cause premature failure of steel and other coating That’s why we measure the concentration of soluble salts. But how clean is clean? That depends on your coating, the standard you are working to, or a combination of the two. The Elcometer 130 …

To  perform this measurement, you would need a whirling hygrometer (sling pyschrometer) such as Elcometer 116. Use it to establish the wet bulb and dry bulb temperature, and then calculate humidity and dewpoint temperature. You can use a conversion tables, such as ones supplied with the Elcometer 116. Alternatively, you can follow this easy procedure …
