DIMENSIONS

A pipe flange is a disc, collar or ring that attaches to pipe with the purpose of providing increased support for strength, blocking off a pipeline or implementing the attachment of more items. They are usually welded or screwed to the pipe end and are connected with bolts.

MATERIALS

  • Blackheart Malleable Iron casting.

DIMENSIONS

  • generally to ASME B16.3 or JIS B2301, depending on manufacturing source.
  • JIS B2301 dimensions are generally considered to be corresponding values to BS143 and BS1256, although some sizes are not exact equivalents.

THREADING

  • BSP pipe thread, to BS.21 (AS 1722, Part 1).
  • The specification for BS 143 fittings is:
    • Taper External (Series R) Taper Internal (Series RC)

WORKING PRESSURES (except flanges)

  • Recommended maximum working pressures are 1379 kPa for water and 1034 kPa for steam, air, gas and oil. NOTE: Working pressures may also be limited by relevant Pressure Piping Codes or Industry regulations.
