Relief Devices

FluidFlow allows you to model two types of relief devices, relief valves, and bursting discs. Users have the option of defining the size of the valve or disc or alternatively, allowing the software to automatically size the components for you based on the system operating conditions. Users can choose from the sizing methodology applied in API (American Petroleum Institute) RP520 Part 1 and ISO 4126-1.

The table below shows the application of different relief device components available in the FluidFlow database:

The table below shows the required data input and the output for the relief device components. Note that the results table varies depending upon the fluid phase state and the visible properties selected by the user.
