GO Galvanised Malleable Iron Bush Range Scr BSP BS EN 10242

Bushings are hollow plugs with threads on the outside and the inside.  They allow for pipe reductions by threading the bushing into a female thread and then threading the small pipe size into the centre of the bushing.  This versatility works well in troubleshooting complex piping systems.

 DIMENSIONS

MATERIALS

  • Blackheart Malleable Iron castings.

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.

TESTING

  • Fittings shall be subject to an internal hydraulic pressure of 2068 kPa without showing any sign of leakage or abnormality.

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.

UNEQUAL SIZES

  • When ordering Reducing Sockets, Nipples, Bushes and Elbows, always state largest size first — e.g. 80 x 40 bush.  When ordering 3- or 4- way fittings, the sizing sequence illustrated below should be adopted.
