r stamp? for pressure vessels (canada)

[marmon]

we had a customer ask us if we could do repairs
on s/s elbows.apparantly we dont need a "pressure vessel" ticket to do repairs
but we do need what they call a "R-stamp"what is this and what do you have to do
to get one.

An R-Stamp is actually a metal stamp that is only issued by the National Board of Boiler and Pressure Vessel Inspectors in the US. This stamp signifies that you have a Certificate of Authorization from the National Board to repair boilers and pressure vessels in accordance with the National Board Inspection Code book. In lieu of trying to get wordy with a complete description, I have included their web site below;

nothing that you know of in canada?

No, because the National Board R-Stamp symbol is Trademark protected and cannot be duplicated by any other organization. Also, the National Board Inspection Code is an international standard.

marmon - Where are you, exactly? The provincial inspection authority for boilers & pressure vessels will be able to tell you exactly what you need to have, in order to perform the work.

Call the Technical Standards & Safety Authority, Boilers & Pressure Vessels Safety Division. Their website is

http://www.tssa.org

and it has all of the contact info. If you really do require an "R" stamp for this work I doubt it will be worth the hassle of getting it, unless you're planning to do a LOT of this kind of work, on an on-going basis. It sounds odd - when I think "elbows", I'm thinking pressure pipe welding shop, not necessarily pressure vessels.
