API standard 650 ground supported liquid storage tanks pontoon openings

API 650 petroleum storage tank pipeline stress and product pressure, tank pressure, uniform or non-uniform temperature difference between the tank wall and the tank bottom, which cause the radial displacement and longitudinal rotation of the API standard 650 ground supported liquid storage tanks tank wall at the opening to affect the oil tank wall The impact is obvious. Therefore, the design must ensure that the load applied by the external pipeline on the opening of the tank wall is within the safety limit. If the stress of the API standard 650 ground supported liquid storage tanks connecting piping is not handled properly, the wall of the API 650 petroleum storage tank may deform or even rupture, causing a major accident.

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