API Std 650 self anchored flatbottom tanks local deviations
API 650 petroleum storage tank has the advantages of high safety: the API Std 650 self anchored flatbottom 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.
Standard Hydrostatic and Pneumatic TestsAfter erection is completed and stress relieving, radiographic examinations, or other similar operations, as may be required, are performed, each tank shall satisfactorily pass a series of hydrostatic and pneumatic tests as prescribed in 7.18.2 through 7.18.6. Whenever a solution film is specified in this section to be applied to welding, linseed oil or another equivalent material for disclosing air leakage may be substituted. In freezing weather, linseed oil or a similarly suitable material shall be used.The attachment welding around all openings and their reinforcements in the walls of the API 620 tank shall be examined by the magnetic-particle method both inside and outside the tank API Std 650 self anchored flatbottom tanks. When the underside of a tank bottom rests directly on the tank grade (and is not accessible after erection), such examination of welding on the underside of the bottom and subsequent air testing may be omitted.
The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the API Std 650 self anchored flatbottom tanks steel materials can be shipped immediately after passing the quality inspection.
