API Std 650 closed top welded storage tanks ladders

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 Std 650 closed top welded 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.

The elastic filling and sealing of floating roof API Std 650 closed top welded storage tanks is to fill the elastic and changeable objects in the sealed envelope, and the sealing purpose depends on the compression deformation of the filler. This kind of sealing effect is good, the requirement of the geometry of tank wall is not too high, and the adaptability is strong. However, the elastic filling and sealing has poor wear resistance and is easy to deform and damage in long-term use.

The API Std 650 closed top welded storage tanks outer wall shall be designed for the purging and operating pressure of the space between the inner and outer tank shells and for the loading from the insulation, the pressure of wind forces, and the roof loading.
The outer tank bottom, shell, and roof shall have a minimum nominal thickness of 3/16 in. (7.65 lbf/ft2) and shall conform to the material requirements of Q.2.3.
