Flange
ASME B16.5 Standard pipes Flanges up to and including 24 inches nominal
ASME B16.47 Standard pipes Flanges above 24 inches

The gasket type and bolt type are generally specified by the standard(s); however, sometimes the standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details (see ASME Code Section VIII Division 1 - Appendix 2). These flanges are recognized by ASME pipes Codes such as ASME B31.1 Power, and ASME B31.3 Process Piping.
Materials for flanges are usually under ASMEdesignation: SA-105 (Specification for Carbon Steel Forgings for Piping Applications) , SA-266 (Specification for Carbon Steel Forgings for Pressure Vessel Components) or SA-182 (Specification for Forged or Rolled Alloy-Steel pipes Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service).
