1 in (25 mm) Blind Flange, 316/316L Stainless Steel, Class 150 | SSFB15031625
Available
This AAP blind flange is made from 316/316L stainless steel to ANSI Class 150 (manufacturer-stated). It is supplied in 6 sizes from 1 in (25 mm) to 6 in (150 mm).
A blind flange has no centre bore. It closes off the end of a pipe run, a valve port or a vessel nozzle, and can be unbolted when you need access for inspection, cleaning or pressure testing.
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
Choose the blind flange that matches the standard, table or class and size of the flange it closes. 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.
