The following sections of API-650 are addressed by the TANK program.
Type A Tanks Type A tanks are constructed primarily of flat surfaces.The maximum allowable tank design pressure in the vapour space of for this type of system is 0.7 barg; this means cargoes must be carried in a fully refrigerated condition at or near atmospheric pressure (normally below 0.25 barg).Atmospheric Storage Tank Specification (Supplement toFor tanks with internal pressure,the shell design thickness shall include the effects of the internal pressure.184.108.40.206.Unless otherwise specified,the design liquid level for calculating shell thicknesses for non-floating roof tanks shall be to the top of the shell,irrespective of operating liquid levels.See Purchasers .API 650Atmospheric Design Pressure - ast-forumOct 21,2007 self anchored storage tanks maximum design pressure#0183;For a liquid storage tank,the pressure rating is the gas pressure at the top of the tank.Atmospheric means no pressure,as when the tank is freely vented to the atmosphere.Tanks designed for atmosheric pressure (in other words,not designed for pressure) are usually still good for a pressure or 1 to 2 water column or more,depending on
