What is the recommended surface treatment for an SS 304 flange?

There are various surface treatments available for SS 304 flanges, but the right choice depends on application requirements. It is crucial to make the surface of the flanges free from defects before applying any coating on them. The surface treatments can help improve the corrosion resistance properties and aesthetics of the ASTM A182 gr F304 reducing flanges.

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.
