Why is accurate coating thickness measurement important?

In petrochemical plants, the importance of this measurement in monitoring the extent of corrosion and detecting potential problems in storage tanks and piping cannot be overemphasized. A thin coating is applied to the parts and components of these facilities to protect the core material from the external elements. Physical wear and potential corrosion reactions can compromise the integrity of these tank and piping assets.

In automotive manufacturing, the application of paint or gloss should be full and uniform to produce outstanding results. Changes in a car's paint job are often indicative of larger problems in the production and quality control of car manufacturing. It's also a way for auto dealers and insurance claims investigators to first learn if the car in question has a built-in problem.

In other words, the importance of accurate knowledge of coating thickness for quality and safety cannot be overemphasized. Even if the coating is only a few nanometers thick (whether for aesthetics or protective function), knowing whether the thickness complies with standards and specifications is a major aspect of ensuring quality and safety (as well as reliability and longevity of a component or part). assets). Whether used in automotive, aircraft, chemical, petrochemical or even medical and scientific fields, coating thickness measurement has always been a critical part of the inspection process.

For this purpose, the measuring principles are usually magnetic induction and eddy current. Non-destructive measurements can be performed on conductive substrates such as aluminum and copper. There are a variety of instruments used in manufacturing, metal processing, offshore installations and asset inspection to get the job done.
