Standard Specification for Carbon Steel Forgings
for Piping Applications
Overview
1.1 This specification covers forged carbon steel
piping components for ambient- and higher-temperature service in pressure
systems. Included are flanges, fittings, valves, and similar parts
ordered either to dimensions specified by the purchaser or to dimensional
standards such as the ANSI and API specifications. Forgings made to
this specification are limited to a maximum weight of 10,000 lb [4540
kg]. Larger forgings may be ordered to other specifications. Tubesheets
and hollow cylindrical forgings for pressure vessel shells are not
included within the limits of this specification. Although this specification
covers some piping components machined from rolled bar and seamless
tubular products, it does not cover raw material produced in these
product forms.
1.2 Supplementary requirements are provided for use
when additional testing or inspection is required. These shall apply
only when specified individually by the purchaser in the order.
1.3 Specification A 266/A 266M covers other steel
forgings and Specifications A 675, A 695, A 696 cover other steel
bars.
1.4 This specification is expressed in both inch-pound
units and SI units. However, unless the order specifies the applicable
"M" specification designation (SI units), the material shall be furnished
to inch-pound units.
1.5 The values stated in either inch-pound units
or SI are to be regarded separately as standard. (A combination of
values from the two systems may result in nonconformance with the
specification.) |
