WebIn addition, a paint thickness measuring instrument can be used to inspect the application and wear of corrosion-resistant protective coatings on metals (e.g., hot-dipped galvanized zinc on steel beams). Thus, a handheld coating or layer thickness meter is a valuable tool used by building, bridge, oil tanker, gas pipeline and petrochemical ... WebTip #1: Choose Quality NDT Equipment. In order to detect thinning early on and prevent more dangerous complications from arising, analysts need precise instruments designed specifically to measure conductive coating thickness. Older or substandard instruments may cost less to acquire upfront than higher-quality alternatives.

Steel corrodes when an electrolyte connects anodes and cathodes on a steel surface. The formation of the corrosion cell causes a flaky iron oxide known as rust. To avoid rust, something must prevent the formation of the corrosion cell. Two common methods for preventing corrosion on steel are: 1. Cathodic … See more The size, shape, and number of pieces to be tested will dictate the appropriate test method. Specified test methods are categorized as either destructive or non-destructive. There are four ways to measure the … See more Precautions: 1. Follow gage manufacturer's instructions 2. Verify gage accuracy regularly using reference standards 3. Ensure that the test surface is free from dirt, grease, oxide, and corrosion products 4. … See more Magnetic coating thickness gages report measurement values in units of linear distance, not coating weight. However, the gage reading can easily be converted to an expression of coating weight. The preceding chart is … See more Duplex coating systems use a combination of two corrosion protection systems—typically paint or powder coating over galvanized steel (hot-dip, electro or zinc spray … See more WebNails and other fasteners are coated to protect them against rust; the thickness of the zinc layer corresponds directly to how long they can resist corrosion...
