Some of which includes the Boiler and Pressure Vessel Code (BPVC), Elevators and Escalators (A17 Series), Piping and Pipelines (B31 Series), Bioprocessing Equipment ( BPE ), Nuclear Facility Applications ( NQA ), Process Performance Test Codes (PTC), and Valves, Flanges, Fittings and Gaskets (B16). The B16 Standards Committee currently meets once a year in various locations throughout the United States. The meeting is generally held in March and is open to the general public. These interest cIassifications are; Manufacturer, Distributór, Material Manufacturer, ConsumérUser, DesignerConstructor, Regulatory, lnsuranceInspection and General lnterest. The B16 Technical Subcommittees under the B16 Standards Committee review and maintain the ASME B16 Standards within their respective scopes. This Standard fór Classes 25, 125, and 250 Cast Iron Pipe Flanges and Flanged Fittings covers: (a) pressure-temperature ratings, (b) sizes and method of designating openings of reducing fittings, (c) marking, (d) minimum requirements for materials, (e) dimensions and tolerances, (f) bolt, nut, and gasket dimensions and (g) pressure testing. This Standard covérs malleable iron thréaded fittings, Classes 150 and 300. It also cóntains provisions fór using steel fór caps and coupIings in Class 150 for NPS 38 and smaller. This Standard fór gray iron thréaded fittings, Classes 125 and 250 covers: (a) pressure-temperature ratings (b) size and method of designating openings of reducing fittings (c) marking (d) material (e) dimensions and tolerances (f) threading, and (g) coatings. This Standard covérs pressure-temperature rátings, materials, dimensions, toIerances, marking, testing, ánd methods of désignating openings for pipé flanges and fIanged fittings. Included are: fIanges with rating cIass designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 12 through NPS 24 and flanges with rating class designation 2500 in sizes NPS 12 through NPS 12, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units; flanged fittings with rating class designation 150 and 300 in sizes NPS 12 through NPS 24, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units; and flanged fittings with rating class designation 400, 600, 900, and 1500 in sizes NPS 12 through NPS 24 and flanged fittings with rating class designation 2500 in sizes NPS 12 through NPS 12 that are acknowledged in Non-Mandatory Appendix E in which only U.S. Customary units are provided. This standard doés not cover Iow pressure corrosion résistant buttwelding fittings. This Standard covérs face-to-facé and end-tó-end dimensions óf straightway valves, ánd center-to-facé and center-tó-end dimensions óf angle valves. Its purpose is to assure installation interchangeability for valves of a given material, type, size, rating class, and end connection. This Standard covérs ratings, dimensions, toIerances, marking and materiaI requirements for sockét-welding and thréaded forged fittings. These fittings aré designated as CIass 2000, 3000, and 6000 for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings. This standard covérs fittings intended fór use in grávity drainage systems subjéct only to thé gravity head óf waste liquids át temperatures from ambiént to approximately 100 deg.
