Asme Code and Standard part three

ASME / ANSI B16.15 - 1985 (R1994) - Cast Bronze Threaded Fittings
This standard relates mainly to throw Classes 125and 250 bronze threaded pipe fittings. Certain conditions are also associated with a wrought or cast plugs, bushings, couplings, and caps. These standards include:
(A) pressure-temperature ratings;
(B) size and method of designating openings of reducing pipe fittings;
(C) sign;
(D) minimum requirements for casting quality and materials;
(E) dimensions and tolerances in the U.S. customary and metric (SI) units;
(F) threading.

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:
(A) Pressure-temperature ratings;
(B) Abbreviations for end connections;
(C) The size and method of designating openings of fittings;
(D) Marking;
(E) Material;
(F) Dimensions and tolerance, and
(G) Tests.

ASME / ANSI B16.20 - 1998 - Metallic Gaskets for Pipe Flanges-Ring-Joint, Spiral-Would, and Jacketed
This standard covers materials, dimensions, tolerances, and markings for metal ring-joint gaskets, spiral-wound metal gaskets and metal jacketed gaskets and filler material. Gasket is a dimension is suitable for use with flanges described in standard reference point ASME / ANSI B16.5, ASME B16.47, and API-6A. This standard covers spiral-wound metal gaskets and metal jacketed gaskets for use with raised face and flat face flanges. Replaces API-601 or API-601.

ASME / ANSI B16.21 - 1992 - Nonmetallic Flat Gaskets for Pipe Flanges
This Standard for nonmetallic flat gaskets for bolted flanged joints in piping include:
(A) the type and size;
(B) materials;
(C) dimensions and tolerances are allowed.

ASME / ANSI B16.22 - 1995 - Wrought Copper and Copper Alloy Solder Joint Pressure Fittings
Standards set the specifications for wrought copper and wrought copper alloy, solder-joint, seamless fittings, designed for use with seamless copper tube conforming to ASTM B 88 (water and general piping system), B 280 (air conditioning and refrigeration service), and B 819 (medical gas systems), as well as fittings intended to be assembled with soldering materials conforming to ASTM B 32, brazing material in accordance with AWS A5.8, or with tapered pipe thread conforming to ASME B1.20.1. This Standard is allied with ASME B16.18, which covers cast copper alloy pressure fittings. It provides requirements for fitting ends suitable for soldering. These standards include:
(A) pressure temperature ratings;
(B) abbreviations for end connections;
(C) size and method of designating openings of fittings;
(D) mark;
(E) material;
(F) the dimensions and tolerances, and
(G) tests.
