How does the size of an SS 304 SORF flange affect its pressure rating?

Generally, as the size of SS 304 SORF flange increases, its pressure rating decreases for a given pressure class. UNS S30400 Larger flanges come with larger seating surfaces of the gaskets and require thicker flange walls for maintaining the pressure rating. It also helps to distribute the load effectively.
