ASME & ANSI CODES

ASME & ANSI CODES

ASME & ANSI CODES

(OP)
Hi,

Can anyone please explain me, what is the difference b/w ASME & ANSI codes, where we mostly use these ones, and i have read about ANSI B 31.3 but how would you convert/compare with ASME?

help me asap

thanks

RE: ASME & ANSI CODES

hahoo-

You'll find your answer in the Forward to B31.3. The current version is ASME B31.3, there is no current ANSI B31.3. The B31.3 code is an ASME code accredited by ANSI.

ASME Committee B31 is organized and operates under procedures of The American Society
of Mechanical Engineers which have been accredited by the American National Standards Institute.

RE: ASME & ANSI CODES

ANSI (American National Standards Institute) is simply an accrediting body for Codes and Standards. They have very specific procedures for accreditation and conduct periodic audits.

This question has been asked before so I thought that adding the web site for people to access might be beneficial.

RE: ASME & ANSI CODES

Yes, its amazing the number of people who keep (incorrectly) referring to these codes as "ANSI" codes and standards. Probably among those that still refer to pipe flanges using the former "lb" rating (i.e.150#) instead of the "new" Class rating introduced over 30 years ago in the then ANSI B16.5-1973.
(The Foreword to B16.5 details its development, including the change to the dual designation (ASME/ANSI) in 1988, and then to just ASME in 1996.)

RE: ASME & ANSI CODES

JohnP,
      Right on!!. I'm getting pretty sick of correcting people who still state ANSI B16.5, ANSI B16.9, ANSI B31.3 etc etc. It's due to the fact that these people never actually read the Codes but just refer to them in an "all knowing" way. I've also seen BS EN 10025 quoted as BS EN 10 025 (with a gap between the first two and last three digits) or even BS EN 10.025  . The problem is most people say it's the same ANSI B31.3 is the same as ASME B31.3 until I ask them to show me ANSI B31.3 listed anywhere except on old out-of-date specifications.

You have hit on a pet hate of mine. Good to see there are others out there who like to be correct when quoting standards!!
