API 650 flat-bottom tanks operating at elevated temperatures

API 650 flat-bottom tanks Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.

API 650 petroleum storage tank has the advantages of high safety: the API 650 flat-bottom tanksinner floating plate floats on the liquid surface, so that the liquid phase has no evaporation space, which can reduce the evaporation loss by 85% to 90%. At the same time, the API 650 petroleum storage tank blocks the air and liquid storage through the floating disk, which reduces air pollution and reduces the degree of fire risk.

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