B31.1 what is current addenda

B31.1 what is current addenda

B31.1 what is current addenda

(OP)
Is the B31.1 2004 with 2005 Addenda the most current (mandatory) or is there a 2006 Addenda? I know the 2007 is not due out until early next year.

Thanks.

RE: B31.1 what is current addenda

The 2006 addenda has been issued last December 15, 2006. It is mandatory as of June 15, 2007.

RE: B31.1 what is current addenda

the B31.1 2004
B31.1 is issued under different editions and addendas,
that do not match other sections of the Code,
I would call the ASME to be sure.

RE: B31.1 what is current addenda

If "Boiler External Piping",which is under ASME Section I, see Table A-360 for the appropriate Edition/Addenda of ASME B31.1.
If "NonBoiler External Piping", then utilize the current  edition of B31.1.
As always, check with the Jurisdiction of installation for additional requirements/limitations.

There are three kinds of people in this world; those who can count and those who can't.
