Design of under-bottom connections for API 650 welded storage tanks
Welded steel API 650 welded storage tanks storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API 650 welded storage tanks all adopt on-site production and installation of storage tanks.
Prefabricating API 650 welded storage tanks components before construction can improve construction efficiency, save time and cost, and is currently a common method for the construction of large vertical storage tanks. The main prefabricated components of a large vertical API 650 welded storage tanks include the tank body, the storage tank wall, the top of the storage tank, the bottom of the storage tank, and the accessories of the storage tank. The prefabrication of the components should follow a reasonable workflow, and carry out appropriate heat treatment and testing, so as to improve manufacturing accuracy.
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 welded storage tanks 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.
