ANSI, ASME, and ASA B16.5 are all standards that specify the dimensions and technical requirements for flanges used in piping systems. Here is a brief overview of each standard:

ANSI B16.5: The American National Standards Institute (ANSI) B16.5 standard covers steel pipe flanges and flanged fittings from NPS 1/2 through NPS 24. It includes requirements for flange facings, bolting, gaskets, and tolerances.

ASME B16.5: The American Society of Mechanical Engineers (ASME) B16.5 standard is identical to ANSI B16.5 and covers the same range of sizes and types of flanges.

ASA B16.5: The American Standards Association (ASA) B16.5 standard is the precursor to ANSI B16.5 and is now obsolete. However, the term “ASA” is still sometimes used colloquially to refer to flanges that comply with ANSI B16.5.

All three standards specify flange dimensions in inches and use the same pressure-temperature ratings for class 150, 300, 600, 900, 1500, and 2500. However, there are some minor differences in the dimensions of the flange faces and bolt circles between the standards. It is important to use the correct standard when selecting flanges for a piping system to ensure proper compatibility and performance.
