Erection of API standard 650 petroleum storage tanks

The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API standard 650 petroleum storage tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.

Welding of Large Steel Storage Tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API standard 650 petroleum storage tanks annular bottom plates together.
b)Joints that connect sections of compression rings and sections of shell stiffeners together. Backup bars may be used for these joints with complete penetration and complete fusion detail.
c)Joints around the periphery of a shell insert plate.
d)Joints that connect the shell to the bottom, unless a method of leak checking is used (see Q.8.2.1).

Unqualified welding quality of API standard 650 petroleum storage tanks is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API standard 650 petroleum storage tanks. How to reasonably control the welding process quality of oil storage tanks?
