How to determine a class of CS A105 flange to be use?

Determining flange rating is quite easy process, for example suppose you want to use SA105 flange in application which has pressure rating of 550 PSIG and at 600 °F. Now you can refer above table to determine flange rating which is in this case is class 300, since its meet the required requirements which you want.
