NOTES:
Imperfections in the flange facing finish shall not exceed the dimensions shown in the table above. Adjacent imperfections shall be
separated by a distance of at least four times the maximum radial projection. A radial projection shall be measured by the
difference between an outer radius and an inner radius encompassing the imperfection where the radii are struck from the
centerline of the bore. Imperfections less than half the depth of the serrations shall not be considered cause for rejection.
Protrusions above the serrations are not permitted.

Slip-On and Threaded Reducing Flanges
NOTES:
1) The hub dimensions shall be at least as large as those of the standard flanges of the size to which the reduction is being made, except
Slip-On and Threaded flanges reducing to a size smaller than those of column 2 may be made from blind flanges. See Example 2.
2) Class 150 threaded flanges do not have a counter-bore. Class 300 and higher pressure flanges will have depth of counter-bore of 0.25
in. for NPS 2 and smaller tapping and 0.38 in. for NPS 2 ½ and larger. The diameter of the counter-bore is the same as that given in the
tables of threaded flanges for the corresponding tapping.
3) Minimum length of effective threads shall be at least equal to dimension T of the corresponding pressure class threaded flange as
shown in tables but does not necessarily extend from the face of the flange.
4) For welding neck flanges, the hub dimensions shall be the same as those of the standard flange of the size to which the reduction is
being made.
5) Reducing socket welding flanges, up to and including NPS 3, are also covered by B16.5.
EXAMPLES:
1) The size designation is NPS 6 x 2 ½ - Class 300 reducing threaded flange. This flange has the following dimensions:
NPS 2 ½ = taper pipe thread tapping (ASME B1.20.1)
12.5 in. = outside diameter of regular NPS 6 Class 300 threaded flange
1.44 in. = thickness of regular NPS 6 Class 300 threaded flange
7.0 in. = diameter of hub for regular NPS 5 Class 300 threaded flange
0.62 in. = height of hub for regular NPS 5 Class 300 threaded flange
Other dimensions are the same as for regular NPS 6 Class 300 threaded flange
2) The size designation is NPS 6 x 2 - Class 300 reducing threaded flange. Use regular NPS 6 Class 300 blind flange tapped with NPS 2
taper pipe thread (ASME B1.20.1)
STAMPING
Stamping is located on the outside diameter of the flange.

NOTES:
1) Flanges not covered by ASME B16.5 should not have the B16.5 stamping. Ex: socket welding
flanges over 3 in.
2) Bore Size should be stamped only on welding neck and socket welding flanges.
3) Bore Size should be stamped as follows:
STD = standard bore
XH = extra heavy bore
XXH = double extra heavy bore
S80 = schedule 80 (all numbered schedules are stamped with the schedule number preceded by an S)
