A516 Gr 70 plates API standard 650 self-anchored tanks

The water dissolved in the oil will be separated out from the oil stored in the API standard 650 self-anchored tanks for a long time, and the acidic water layer will appear at the bottom of the API standard 650 self-anchored tanks for a long time, which will accelerate the corrosion of the API standard 650 self-anchored tanks and cause the wall thinning and even leakage. With the increase of service life, the API standard 650 self-anchored tanks must be inspected and cleaned regularly to check the hidden danger.
