API Std 650 carbon and low-alloy steel tanks purchaser
API 650 petroleum storage tank has the advantages of high safety: the API Std 650 carbon and low-alloy steel 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 API Std 650 carbon and low-alloy steel tanks must go through strict inspection before putting into use. Inspection of plate groove of API Std 650 carbon and low-alloy steel tanks, vertical oil tank: After finishing the groove processing of oil tank plate, it is necessary to conduct dye penetrant inspection on the groove. This process is mainly aimed at the hard damage of groove in the machining process and the defects of the plate itself. If any defect is found, it shall be processed again until the defect disappears.
The increased uplift described in API Standard 620 tank Appendix Q is intended to apply to the size of the ringwall and foundation but not the anchorage. For tanks with an internal design pressure of 1 lbf/in.2 gauge and over, the uplift, if any, shall be calculated under the combined conditions of 1.25 times the internal design condition plus the design wind load on the API Std 650 carbon and low-alloy steel tanks shell and roof.
