API 650 open-top tanks automatic float-level gauge
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 650 open-top tanks. 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.

}The structure of the API 650 open-top tanks foundation mainly includes the insulating anticorrosion layer on the top surface of the foundation, the tank wall support, the edge retaining structure, the sand cushion, the oil and water barrier, the detection signal tube and other structures. The construction materials and requirements of each basic structure of the storage tank are different. After the structure of the API 650 open-top tanks foundation is built in accordance with the construction requirements, the settlement of the storage tank foundation needs to be observed, and the uneven settlement value of the storage tank foundation should be within the allowable safety range.
