ASTM A53 pipe API 650 carbon steel tank

Under the action of the earthquake, API 650 storage tank is mainly damaged by the phenomenon of the lower part of the API 650 carbon steel tank tank wall. Therefore, the key point of seismic calculation is to prevent the tank wall from buckling under axial pressure.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API 650 carbon steel tank roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.

The preparatory work before the construction of the API 650 carbon steel tank is an important part of the oil tank project. Material purchase preparation before the construction of the API 650 carbon steel tank:
Before API 650 carbon steel tank construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.
