ANSI/ASME Y32.2.3-1949 (R1999)
Graphic Symbols for Pipe Fittings, Valves and Piping
This Standard has been developed for use on drawings. Architects, engineers, and contractors, by the use of these symbols on their plans, will have a standard method of indication for pipe fittings, valves piping and allied items. Confusion in the interpretations of requirements can thus be avoided.
