These are sometimes referred to as atmospheric tanks. 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 size and configuration. atmospheric tank design pressure.
Atmospheric Tank Design Pressure, There isnt an exact internal pressure value for atmospheric tanks rather you your company as Subcontractor your Contractor must establish the internal pressure for your specific tank. Design Pressure Although atmospheric storage tanks are intended to operate at about atmospheric pressure in practice they do have a design. Atmospheric pressure varies depending on your height above or below sea level.

The design of these tanks is governed by API Standard 620. API 650 only covers tanks that support the whole bottom evenly and tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. API 650 Annex M. The design of atmospheric storage tanks in general is governed by API Std 620 Design and construction of large welded low-pressure storage tanks and API Std 650 Welded steel tanks for oil storage. Tanks should be suitable for their operational duty and all reasonably expected forces such as tank contents ground settlement frost wind and snow loadings. If youre below sea level atmospheric pressure will be higher.

In the tank data sheet you can write. Tanks with design pressures above 25 psig but not more than 15 psig are called low-pressure tanks. The compressed air in the tank imparts pressure to water stored in the tank and connected distribution piping. These tanks are used to store liquids for various chemical engineering and other purposes for varying durations. Maybe you should follow the design codes for atmospheric tanks.

A vessel or pressure vessel is defined as a closed container designed to hold gases or liquids at a pressure different from the ambient pressure. As you get higher theres less atmosphere pressing down and so the pressure is lower. And the total shell design external pressure is the greater of Pe excluding wind or W04Pe. This Practice covers storage tanks that have design internal pressures of 172 kPa 25 psig or less see.
