API 650 flexible liquid storage tanks requirement

The effect of air pressure on the API 650 flexible liquid storage tanks tank walls of the API 650 tank must be considered when the design pressure is greater than 2 kPa.The fixed point method can be used to design the tank wall of atmospheric or micro internal pressure API 650 flexible liquid storage tanks storage tank.

The cleanliness of the API 650 flexible liquid storage tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API 650 flexible liquid storage tanks clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API 650 flexible liquid storage tanks is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.

Welding of API 620 Steel Storage Tank Primary Components
The following primary components shall be joined with double butt-welds that have complete penetration and complete fusion except as noted:
Longitudinal and circumferential shell joints and joints that connect the annular bottom plates together. When approved by API 650 flexible liquid storage tanks Purchaser, these may be welded from a single side provided temporary non-fusible backing is used with complete penetration and complete fusion. Both sides of the joint shall be 100% visually examined as specified in 7.15.5.
