Pit Depth Measurement
Definition - What does Pit Depth Measurement mean?
Pit depth measurement is an important prerequisite of corrosion inspectors. In this type of measurement, the pits are measured with extreme accuracy and ease by using a pit depth gauge.
Taking this measurement helps in plotting corrosion profiles in a fast and reliable manner by simply turning the indicator and probe alongside the bridging bar.
Corrosionpedia explains Pit Depth Measurement
One of the most widely used tools to measure the depth and extent of pits brought about by corrosion is a pit gauge. Taking this measurement with the help of an appropriate tool is vital in piping, boilers, vessels, storage tanks, aircraft components as well as structures such as bridges.
Measurement via pit gauge is not as cumbersome as using an ordinary depth gauge, making it a dependable tool for field corrosion inspection. For instance, modern pit depth gauges are now computerized and are capable of mapping the areas of corrosion or mass loss. Yet, even the simplest and latest pit gauge depth tool can deliver precise measurements.
Pit depths should be measured and noted to maintain standard operations by knowing when to initiate repair. For instance, pitting on engine blades necessitates repair when it has reached its maximum depth. In cases of extreme pitting, the blade is no longer qualified for repair. Instead, the engine blade should be scrapped entirely. The same goes for other industrial parts. Thus, timely and accurate measurement helps industries save huge sums of money.
