Note :
  • 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.

Note :
  • MSS SP-44 flanges are designated series A flanges in ASME B16.47. It also covers flanges in the range NPS 12 to 24, these being equivalent to ASME /ANSI B16.5 flanges in the same range (except for the addition of NPS 22 in MSS SP-44).
  • API 605 has been cancelled. API 605 flanges are designated series B flanges in ASME B16.47. Ranges quoted are based on ASME B16.47 series B.
