API standard 650 cylindrical liquid-storage tank snow load

Oil tank is often used to store crude oil, diesel oil, gasoline and other oil. The main structure of API standard 650 cylindrical liquid-storage tank is composed of tank top, tank wall, tank bottom and accessories. The API standard 650 cylindrical liquid-storage tank should be inspected after the completion of construction, and the detection methods of different structure positions are different Tank wall inspection: for the newly built oil tank, water filling test shall be conducted to check whether the tank wall is tight, and the appearance inspection shall be conducted for the tank wall plate and weld Tank wall thickness detection: the oil tank wall thickness is mainly detected by ultrasonic wave, with high efficiency

Changes in Tank ShapeIf in any of the foregoing tests there is an excessive rise of the bottom of the tank around the boundary of contact with grade, or off its foundations, or if any of the specified conditions of test loading cause other appreciable changes in the shape of the tank, the design shall be reviewed and means shall be provided in the tank for holding the shape within permissible limits under all conditions of loading,API standard 650 cylindrical liquid-storage tank. Additional TestsThe tests prescribed in API 620 tank 7.18 are believed to be sufficient for most tanks constructed according to these rules; if, in the opinion of the designer, additional tests are needed to investigate the safety of a tank under certain other conditions of loading, as determined from the design computations, these tests shall be made on the tank involved in addition to the tests specified in this standard.

Upon completion of construction, provide Purchaser with copies of Field Erected API standard 650 cylindrical liquid-storage tank Storage Tank Datasheets in accordance with Appendix L of API 650, which reflects the as-built conditions, certifying that the tank conforms with the requirements of this specification.
