5052 aluminum shapes API standard 650 flat-bottom steel tanks

When the day light gradually decreases, the temperature of oil in the API standard 650 flat-bottom steel tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API standard 650 flat-bottom steel tanks will also decrease. When the pressure in the API standard 650 flat-bottom steel tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API standard 650 flat-bottom steel tanks through the open vacuum valve, which is the "suction" process of the oil tank.

This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API standard 650 flat-bottom steel tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.

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 standard 650 flat-bottom steel 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.
