> MSS SP-44 flanges are designated series A flanges in ASME B16.47.
> API 605 has been cancelled. API 605 flanges are designated series B flanges in ASME B16.47. > BS 10, although obsolete, remains in use for light weight economy stainless steel flanges.
> Within specification ANSI B16.5, plate can only be used to provide blind flanges.
> Most small BS 10 flanges are made from bar.
> Castings are not included in this manual.
Materials:Most standard specify the material from which the flanges is produced. The purchaser should specify the exact requirements.
Flange Size:All sizes and grades compatible to standard pipe flanges and wall thicknesses (pressure ratings) are available. The table bellow provides a summary.
Flange Face:There are various face configurations for flanges. Typically: flat face, raised face, tongue and groove, and ring joint.
Face Finish:The finish on the face of a flange is measured as an Arithmetical Average Roughness Height (AARH). The finish is determined by the standard used. For example, ANSI B16.5 specifies face finishes within a range 125AARH - 500AARH (3.2 Ra to 12.5 Ra). Other finishes are available on request, for example 1.6 Ra Max. 1.6/3.2 Ra, 3.2/6.3 Ra or 6.3/12.5 Ra. The range 3.2/6.3 is most common.
