Carton Information
Specifcations
All standard or “Class 125” Cast Iron Flanged Fittings in sizes listed are
made to ASME and are marked 125 for pipe sizes 12 NPS (300 DN)and
smaller; and have plain faces. Unless otherwise specifed, cast iron fanges
and fttings are drilled and faced in accordance with ASME B 16.1.
Coatings
Flanged fttings are available in both black and galvanized. Consult an
Anvil Representative for available sizes.
Sizes
Size of all fttings scheduled indicates nominal pipe diameter of
ports. Standard reducing elbows carry the same dimensions center-
to-face as regular elbows of largest straight size.
Ordering
To order reducing companion fanges, specify threaded or reduced
size frst, then the outside diameter of fange wanted. For instance,
if a reducing fange is required to connect a 5-inch pipe to an 8-inch
fanged valve or ftting having a 13 1/2-inch O.D. fange, order: 5 x 13 1/2-
inch standard reducing fange.
Dimensions
Bolt holes, for bolts smaller than 1 3/4 inches (44mm) in diameter are
drilled 1/8 inch larger than the bolt diameter; 1 3 /4 inch (44mm) and
larger, bolt holes are 1/4 inch (6mm)larger than bolt diameter. Bolt holes
straddle the center line. Bolt holes are spot faced on order only.
Tolerances
An inspection limit of plus or minus 1/32 inch (1mm) shall be allowed on
all center to contact surface dimensions for sizes up to and including
10 NPS (250 DN); plus or minus 1/16 inch (2mm)on sizes larger than 10
NPS (250 DN). Inspection limit of plus or minus 1/16 inch (2mm)shall
be allowed on all contact surface to contact surface dimensions for
sizes up to and including 10 NPS (250 DN); plus or minus 1/8 inch (3mm)
on sizes larger than 10 NPS (250 DN). The largest opening in the ftting
governs the tolerance to be applied to all openings.
