The American National Standard ANSI B16.5 “Steel Pipe Flanges and Flange Fittings” is a relatively complete, mature, and internationally popular and universal advanced standard. The pressure piping application standard system composed of this standard and other related ANSI, API, ASTM, and MSS is formed on the basis of a large number of experimental studies and has undergone decades of practical testing. Therefore, it is a scientific and advanced standard. Widely accepted by various countries.
