Does ASME Require That All Vessels Be NB Registered?
Does ASME Require That All Vessels Be NB Registered?
(OP)
While employed previously by an ASME Code shop I came to understand that all ASME Code stamped vessels had a NB number and a copy of the U-1 data report was posted to the NB HQ (along with a registration fee). As a consultant I have encountered on a number of occasions vessels that were Code stamped, but not registered at the NB. Further, I was advised by an experienced and knowledgeable fabricator that the the NB registration is a jurisdictional requirement, not an ASME requirement. I never took the opportunity to verify the correctness of his statement. Considering the number of Code stamped vessels that are not registered with the NB, his statement seems plausible. Was he correct about this? Thanks for your responses.

and specially the registered numbers have to be in ascending sequence starting with the No. 1 ,
The problems thatcan arise for not havuing a registration with the Nt'l Bd are a diferent thing and falls from shipping the vessel into the diferent jurisdictions, whether or not the jurisdiction will accept the vessel with or w/o registration. you donot have it send it back to the mfr.
hope this helps,

Your fabricator is correct, the NB stamping is a requirement of the jurisdictional authority and/or the customer/user. It is not an ASME requirement.
BJaffa is also correct in that there are many benefits to having the equipment registered with the NB, especially when it comes to documentation for future repairs/alterations or when selling the equipment.

ASME is a code of construction(I know you know this).
NB is more or less the enforcement of same.
An ASME stamp states it was constructed to code as the code existed at the time of original construction. The NB stamp says yep, it fersure was because one of our inspectors watched it happen and our field auditors ensure they maintain the ability to do as the ASME code dictates.
So inpractice, the fabricator can claim it was built to ASME and stamp it so, but without the NB stamp, who really knows.
That's why jurisdictions who are serious about pressure vessel safety demand both stamps.
I can place a 'USDA Select' tattoo on my wife's butt, but that don't mean she really is....

The only stamping on a Code vessel is ASME nameplate. The NB stuff kicks in for in-service equipment.

Try this
www.nationalboard.org
Then go to the Site Directory,Look for NB Synopsis of Boiler and PV Laws.

I checked out the NBIC link and found no reference to NB stamping of NEW vessels. After re-reading and re-reading the earlier post about this issue, I believe that the NB reference must be in regards to in-service vessels. And, as we know, the R-stamp is applied for repairs.
spector,
While one should accept the ASME stamp as the manufacturer's comfirmation that the vessel was per Code, I also remain respectfully cautious about the accuracy of that assurance. I believe that the manufacturer really believes that the Code requirements were met. But, we all make mistakes or misinterpretations (especially about the dreaded UW-11(a)(5)(b) joint efficiency issue). The signature of the AI on the data report is also reassuring, but I never forget that the the signature only means "that to be best of my knowledge" the vessel complies with the Code. I am in no way a skeptic about the system as I find that it usually work well, especially for the basic types of vessels. It's the more complicated vessels where I find the problems from the original manufacturer.

There once was an org. by the name of the Uniform Boiler and PV Laws Society. They published a check list for what you wish. They are no more. The NB has taken this over and now has a publication NB-370 NB Synopsis of Boiler and PV Laws,Rules,and Regs. It is $100.
The other method is use the link I sent and contact each jurisdiction.
Nothing is free.

see Synopsis of Boiler and Pressure Vessel Laws, Rules and Regulations
also always check local juristiction when doing new installations. I had several vessels in Seattle that met State requirements for stamping, but not city regulations.
RE: Does ASME Require That All Vessels Be NB Registered?
You make reference to an NB stamp. Could you please clarify which stamp you are talking about and is it applied to a new vessel? To the best of my knowledge, an ASME vessel comes with an ASME stamp only. Yes, a NB AI signs the data report for an ASME vessel. Am I misreading your post? I apologize in advance about my confusion here. Thank you.

Not to be confused with any of the 'R' variety stamps, as repair and registration are two different functions of the national board.
