This specification2 covers forged carbon steel piping components for ambient- and highertemperature service in pressure systems. Included are flanges, fittings, valves, and similar parts to specified dimensions or to dimensional standards such as those ANSI and API specifications that are referenced in Section 2. Forgings made to this specification are limited to a maximum weight of 10 000 Ib (4540 kg). Tubesheets and hollow cylindrical forgings for pressure vessel shells are not included within the scope of this specification. Although this specification covers some piping components machined from rolled bar and seamless tubular products, (see 4.4) it does not cover raw material produced in these product forms.

Supplementary requirements are provided for use when additional testing or inspection is desired. These shall apply only when specified individually by the purchaser in the order.

Specifications covering other steel forgings are listed in 2.1 and 2.2.

The values stated in inch-pound units are to be regarded as the standard.

NO!E I.-The dimensionless designator NPS (nommal pipe size) has been substituted in this standard for such traditional terms as "nominal diameter," "size" and "nominal size."
