What is the maximum pressure in an atmospheric storage tank?

The maximum pressure for vapor or gas space of an atmospheric storage tank is 2.5 psi, and for a low pressure storage tank is 15 psi. If the pressure is more than 15 psi, the liquid cannot be stored in in the storage tank and it is necessary to be stored in a pressure vessel.See all results for this What is an atmospheric tank used for?Atmospheric tanks are used for the storage of liquids at ambient temperature and also for the storage of refrigerated liquids, as described below. Meherwan P. Boyce, in Gas Turbine Engineering Handbook (Fourth Edition), 2012See all results for this What is the construction code for an atmospheric storage tank?The construction code for the atmospheric storage tank is API STD 650, and for a low pressure storage tank is API STD 620. These cover the minimum requirements for design, materials, fabrication, inspection and testing.See all results for this Why can't I design a pressure tank for a storage tank?Inherently safer design with respect to equipment pressure and vacuum ratings is also generally not feasible for storage tanks, as it would require a pressure vessel, which would increase the cost of fabrication.See all results for this question
