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.)
