ASME B16.34

Abstract

<strong>General</strong> <br>This Standard applies to new construction and covers pressure&#8211;temperature ratings, dimensions, tolerances, materials, nondestructive examination requirements, testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end and wafer or flangeless valves of steel, nickel-base alloys, and other alloys shown in Table 1. Wafer or flangeless valves, bolted or through-bolt types, that are installed between flanges or against a flange are treated as flanged-end valves. Alternative rules for NPS 2&#189; and smaller valves are given in Mandatory Appendix V.
