CSA G40.21 grade 260WT plates API Std 650 welded aluminum storage tanks

During heavy rain, closely observe the change of the water level in the storage area of the API Std 650 welded aluminum storage tanks. If the water level rises to the dangerous range, drain the water immediately. There are more thunderstorms in heavy rain, and lightning protection devices should be installed in the API Std 650 welded aluminum storage tanks area to avoid lightning accidents. Observe the groundwater level of the API Std 650 welded aluminum storage tanks area at any time, clean and dredge the drainage ditch in time to ensure unobstructed drainage, and prevent the bottom of the API Std 650 welded aluminum storage tanks from leaking and rusting due to untimely drainage.

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 Std 650 welded aluminum storage tanks 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.

One of the most widely used design codes is the API 650 Standard, from the American Petroleum Institute. The main objective of this standards API Std 650 welded aluminum storage tanks is, through the requirements contained in its various sections, to facilitate the purchase and construction of vertical, aboveground, welded fabricated tanks assuring that required safety regulations are met.
