The ASME - American Society of Mechanical Engineers - ASME/ANSI B16 Standards covers pipes and fittings in cast iron, cast bronze, wrought copper and steel.

ASME/ANSI B16.5 - Pipe Flanges & Flanged Fittings

The ASME B16.5 - 1996 Pipe Flanges and Flange Fittings standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings.
The standard includes flanges with rating class designations 150, 300, 400, 600, 900, 1500, and 2500 in sizes NPS 1/2 through NPS 24, with requirements given in both metric and U.S. units. The Standard is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forges, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flanged gaskets, and flanged joints.

ASME/ANSI B16.10 - 2000 - FACE-TO-FACE AND END-TO-END DIMENSIONS OF VALVES

This Standard covers face-to-face and end-to-end dimensions of straightway valves, and center-to-face and center-to-end dimensions of angle valves. Its purpose is to assure installation interchangeability for valves of a given material, type size, rating class, and end connection.

ASME/ANSI B16.18 - 1984 (R1994) - CAST COPPER ALLOY SOLDER JOINT PRESSURE FITTINGS

This Standard for cast copper alloy solder joint pressure fittings designed for use with copper water tube, establishes requirements for:

1. Pressure-temperature ratings
2. Abbreviations for end connections
3. Sizes and method designating opening of fittings
4. Marking
5. Material
6. Dimensions and tolerances
7. Tests

ASME/ANSI B16.33 - 1990 - MANUALLY OPERATED METALLIC GAS VALVES FOR USE IN GAS PIPING SYSTEMS UP TO 124 PSIG

Generally this Standard covers requirements for manually operated metallic valves sizes NPS 1.2 through NPS 2, for outdoor installation as gas shut-off valves at the end of the gas service line and before the gas regulator and meter where the designated gauge pressure of the gas piping system does not exceed 125 psi (8.6 bar). The Standard applies to valves operated in a temperature environment between 0.20°F and 150°F (0.29°C and 66°C). Design this Standard set forth the minimum capabilities, characteristics, and properties, which a valve at the time of manufacture must possess, in order to be considered suitable for use in gas piping systems.

ASME/ANSI B16.34 - 1996 - FLANGED, THREADED, AND WELDED-END

This Standard applies to new valve construction and cover pressure-temperature ratings, dimensions, tolerances, materials, non-destructive examination requirements, testing, and marking for cast, forged, and fabricated flanged, threaded, and welding end, and wafer or flangeless valves of steel, nickel-based 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 shall be treated as flanged-end valve.

Maximum allowable working pressure (psig) and temperature ratings for steel pipe flanges and flanged fittings according to the American National Standard ANSI B16.5 - 1988.
