API Std 650 welded steel oil storage tanks selection guidelines

Ultrasonic testing can find the internal defects of API Std 650 welded steel oil storage tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API Std 650 welded steel oil storage tanks and so on metal oil tanks. The feature of this method is convenient and fast.

Temporary Openings after Hydrostatic Test
When approved by the Purchaser in writing, and only in the case of tanks which when complete have no shell penetrations, it is permitted to restore by welding up to four temporary shell openings after the hydrostatic test in accordance with the provisions of this section. Each temporary opening shall be restored by the insertion of a shell plate that matches the thickness and specification of adjacent shell material, and is welded into place with full fusion butt-welds. The API Std 650 welded steel oil storage tanks insert plate shall be round with diameter no less than 24 in. and no greater than 42 in.

API 650 petroleum storage tank has the advantages of high safety: the API Std 650 welded steel oil storage 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.
