Calculate ASME B16.5 pipe flange rated pressure versus temperature (Table 2 SI values).
Rated pressure can be calculated by material group, or pipe flange class (class 150, 300, 400, 600, 900, 1500 and 2500). The rated pressure values are valid from -26 C, to the maximum data temperature. For temperatures greater than the maximum data temperature, the rated pressure can be calculated using either the constant value or constant slope option (these options should be used carefully - engineering judgment is required). Otherwise the rated pressure should be set to zero, as per the code. For temperatures below -26 C, addditional testing may be required (engineering judgment is required).
Use the Data Plot option to plot the rated pressure versus temperature for the selected material. Use the Data Table option to display the data table in the popup window (Table A-1 or K-1). Use the Result Table option to display a table of rated pressure versus material group or flange class. Change units on the setup page.
