CSA G40.21 grade 300W plates API 650 unanchored flat-bottom tank
The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API 650 unanchored flat-bottom tank External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.
Surface Inspection of low-pressure storage tank Component PartsBefore assembly, unless already so certified by shop inspectors, all sidewall plates or sections and roof and bottom plates shall be inspected for thickness, freedom from injurious defects, and soundness of any welded joints.Check of Dimensions of API 650 unanchored flat-bottom tank Component PartsAll formed plates and curved sections shall be checked for conformance with the planned dimensions and cross section. For unusual repairs the inspector should keep a record of measurements taken at sufficient intervals to constitute a satisfactory record.Check of Chemical and Physical Property DataThe inspector shall check the material being assembled by the lists of the plates from the mill, their heat numbers, chemical analyses, and mechanical properties as given on mill reports and shall see that copies are available to be attached to the Manufacturer’s report.
Compared with the external floating roof API 650 unanchored flat-bottom tank, the internal floating roof API 650 unanchored flat-bottom tank has the advantages of protecting the floating roof from wind and rain and ensuring the quality of liquid storage under the floating roof. At the same time, because the inner floating plate is in the tank, there is no rain and snow load, so the central drainage pipe and escalator and other accessories on the floating plate can be omitted. In addition, under the same sealing conditions, the internal floating roof tank can further reduce the evaporation loss compared with the external floating roof tank.
