AAP describes plate flanges as mainly used for light duty, lower pressure or non-critical applications. They are cut and machined from plate steel.
AAP lists AS4087 PN16 (manufacturer-stated) at an allowable operating pressure of 1,600 kPa, a maximum operating pressure of 1,920 kPa and an allowable site test pressure of 2,000 kPa.

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.
