Use a pressure of 16 kilograms; select a blind flange of the appropriate size based on the diameter of your pipe

You can refer to 20592; I checked that for carbon steel flanges of PN16, the maximum allowable operating pressure at 300 degrees is 11 kilograms. The same table can likely be used for blind flanges as well – in other words, if your pipes are not exposed to temperatures over 300 degrees, you can choose PN16 flanges
