2024 aluminum shapes API 650 anchored liquid-storage tanks

Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API 650 anchored liquid-storage tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API 650 anchored liquid-storage tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.

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 anchored 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.

The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API 650 anchored liquid-storage tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.
