PiPe FiTTiNGS FlaNGeS Galvanised Malleable Fittings MATERIALS Blackheart Malleable Iron castings. WORKING PRESSURES (except flanges) Recommended maximum working pressures are 1379 kPa for water and 1034 kPa for steam, air, gas and oil. DIMENSIONS generally to ASME B16.3 or JIS B2301, depending on manufacturing source. JIS B2301 dimensions are generally considered to be corresponding NOTE: Working pressures may also be limited by relevant values to BS143 and BS1256, although some sizes are not Pressure Piping Codes or Industry regulations. exact equivalents. UNEQUAL SIZES THREADING is BSP pipe thread, to BS.21 When ordering Reducing Sockets, Nipples, Bushes (AS 1722, Part 1). and Elbows, always state largest size first — e.g. 80 x 40 bush. The specification for BS 143 fittings is: Taper External (Series R) Taper Internal (Series RC) When ordering 3- or 4- way fittings, the sizing sequence illustrated below should be adopted.
