ASME B16.34 Valves Flanged Threaded and Welding End

ASME B16.34 Valves Flanged Threaded and Welding End

This ASME B16.34 Valves Flanged Threaded and Welding End applies to new construction and covers pressure, 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 1/2 and smaller valves are given in Mandatory Appendix V. keyword: ASME B16.34 Valves Flanged, asme b16.34 annex b, asme b16.34 pressure rating, asme b16.34 standard.
