A662 Gr C plates API Std 650 storage tanks

The calculated thickness of the above-mentioned wall panels required by the hydrostatic pressure is also It API Std 650 storage tanks should be increased by the same ratio, unless special analysis is performed to determine the seismic overturning moment and the corresponding stress at the bottom of the wall of each layer of API 650 tank.

Hydrostatic Test
The API Std 650 storage tanks product shall be vented to the atmosphere when it is filled with or emptied of water. During water filling, the elevations of at least four equidistant points at the bottom of the tank shell and on top of the ringwall or slab shall be checked. Differential settlement, or uniform settlement of substantial magnitude, requires an immediate stop to water filling. Any further filling with water will depend on an evaluation of the measured settlement.

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