API standard 650 liquid storage tanks shell reinforcing plates
API 650 petroleum storage tank specifications and standards are documents verified by the customer (owner) under different operating conditions; however, API standard 650 liquid storage tanks it must be verified whether these API 650 petroleum storage tank documents are suitable for use and whether they comply with applicable design specifications and/or specifications.
The tank shall be filled with water to the design liquid level unless height is limited as noted in API 620 standard Q.8.1. After the tank is filled with water and before the pneumatic pressure is applied, anchorage, if provided, shall be tightened against the hold-down brackets. All welds in the API standard 650 liquid storage tanks shell, including the corner weld between the shell and the bottom, shall be visually checked for tightness.
Requirements for prefabrication of the top of large vertical API standard 650 liquid storage tanks: The prefabrication of the tank top shall be prefabricated in blocks according to the drawings. Pay attention to the spacing of the welds after installation when setting out the material. Reinforcing ribs should be formed and inspected with an arc-shaped template. When a single top plate needs to be spliced, butt joints should be used. The forming of a single top plate should be welded between the reinforcing ribs and the top plate on the mould. After forming, check with an arc-shaped sample plate, and the gap should not be greater than 10 mm.
