Description

ANSI B16.5 CLASS 150 FLANGE WELDING NECK SCH40 STEEL PIPE A105 CARBON STEEL AND SS304 STAINLESS STEEL FORGED FLANGE

ASME/ANSI B16.5 provides

  • weld neck
  • slip-on
  • socket weld
  • threaded
  • lap joint
  • blind

flange dimensions for pipes ranging 1/2" to 24" - in classes ranging 150 to 2500. Note that the ratings are in steps with terminology like ASME class xxx or API xxxx.

In general you need to specify the schedule (thickness) of the connected pipe when it is being butt welded to the flange. Socket welded and threaded connections is unaffected by wall thickness and should only require the OD.
