1 in (25 mm) RF Flange, 316/316L Stainless Steel, Class 150 | SSFS15031625
Available
This AAP raised face flange is made from 316/316L stainless steel to ANSI Class 150 (manufacturer-stated). It is supplied in 7 sizes from 3/4 in (20 mm) to 6 in (150 mm).
A raised face flange concentrates the bolt load on a smaller gasket area, which increases the pressure the joint can contain. It is common in process plant pipework.
AAP's catalogue gives the dimensions for this stainless range but does not publish a pressure rating, so confirm the allowable pressure for 316/316L at your operating temperature with AIMS before ordering.

Selecting the right option
Check the pipe outside diameter against the flange bore before ordering. Match the standard and table or class to the mating flange and compare the drilling dimensions listed on this page, because flanges made to different standards are not interchangeable. Gaskets and bolting are not part of this listing. If you are not sure what suits, contact AIMS with the standard and size of the mating flange.
