Cast Iron Flanged Fittings
Class 250 (Extra Heavy)
Specifcations
All Extra Heavy or “Class 250” Cast Iron Flanged Fittings in sizes
listed are made to ASME B16.1, and are marked “250”. All Class
250 Cast Iron Flange Fittings are faced and drilled to ASME B 16.1,
unless otherwise specifed.
Anvil Fittings’ sizes 1" NPS to 10" NPS
(25 to 250 DN)
shown in
this section are included in the “List of Inspected Fire Protec-
tion Equipment and Materials” issued by the Underwriters’ Lab-
oratories, Inc.
Coatings
Flanged fttings are available in both black and galvanized.
Consult an Anvil Representative for available sizes.
Sizes
To avoid delay in shipment, where other than sizes given are
ordered, we carry in stock reducing fanges, the use of which,
in connection with straight or reducing fttings carried in stock,
enable us to fll orders promptly for reducing sizes where
specifcations will permit reduction made in this manner. The
reducing fanges furnished are the same thickness as the regular
companion fange of the corresponding outside diameter and
will be drilled to the template corresponding to the outside
diameter unless otherwise ordered. For fttings reduced in this
manner, please specify “reduce by fanges if necessary.”
To order reducing companion fanges, specify threaded or re-
duced size frst and follow with outside diameter. For instance, if
a reducing fange is required to connect a 4-inch
(100 DN)
pipe to
a 6-inch
(150 DN)
valve or ftting having a 12
