API 650 open top welded storage tanks convective water parameters

API 650 open top welded storage tanks Drain hole: The drain hole is generally installed at the bottom of the oil tank, used to remove sludge when cleaning the oil tank, and usually used to drain the sewage in the tank. API 650 open top welded storage tanks Safety valve: The role of the safety valve is to play a safety role when the breathing valve fails during the operation of the oil tank. Its working pressure is slightly higher than the pressure of the breathing valve, which can prevent the tank from being damaged due to the high positive or negative pressure in the tank. The safety valve is usually installed in the middle of the API 650 open top welded storage tanks top.

Welding of Large Steel Storage Tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API 650 open top welded 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).

When API 650 storage tank is designed, when the design pressure is small F2 kPa, the impact of air pressure on the API 650 open top welded storage tanks tank wall thickness is not considered in the tank wall design.
