How to calculate flange rating as per ASME B16.5 with example II flange rating kaise nikalen 🔥🔥

So, how to select the proper flange rating?
Find the rating table that applies to your flange scrolling below (this depends on the material of the flange, as flanges with different material grades have different pressure ratings)
Determine the max working temperature in your piping system (i.e. select one line in the table)
Select a rating based on the maximum pressure you expect at that temperature level (i.e. select one column in that line)
Voilà, you have the required rating!
To help you do this easily, find below the ASME B16.34 pressure rating charts for the most common flange materials (carbon, alloy, stainless).
