API 650 carbon steel tank welding symbols

API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API 650 carbon steel tank storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.

Vertical Storage Tanks Security against Damage
The assemblies of relieving devices shall be secured against damage in service, the effects of storms, or mishandling. Access ladders and platforms that meet API 650 carbon steel tank plant safety rules are suggested.
Vacuum-relieving Devices
A vacuum-relieving device, when used, shall be as direct in inflow as possible with no pockets where moisture can collect, and it shall have no piping except a weather hood ahead of the inlet. An adequate vacuum-air inlet shall also be provided.

The head of API 650 carbon steel tank etc. vertical oil tank is the end cover on the top of vertical oil tank. It is used to separate the oil stored in the tank and the medium outside the tank, and also used to bear the pressure on the top of the vertical oil tank. The quality of the head is closely related to the long-term safety of the API 650 carbon steel tank. The head surface can be divided into convex shape, cone shape and flat shape according to its shape. The oil tank head can not be disassembled after welding.
