U Stamp on PED Vessels
U Stamp on PED Vessels
(OP)
For pressure vessels that are CE marked but designed, fabricated, and tested to ASME VIII Div 1, with Notified Body involvement to extent required by PED, is there any reason to have vessels U Stamped as well? I think that where PED conformance is mandated then CE Marking confirms this and U Stamp is superfluous - any comments?

I would be interested to know whether deleting U stamp requirement would actually save me any money though.

We have supplied vessels with U stamps and PED compliance even though the final end user was in Australia!!! It was because half the spec team were American and the other half were French, so we got a cover-it-all specification.
I presume that they had to do some work at their end to get it approved in Australia, but that wasn't my problem.
RE: U Stamp on PED Vessels
I'm having to come to terms with PED requirements for latest project and feel that retaining ASME U stamp is over-specifying (PED is mandatory in this case). On an almost related issue, I was interested in the forum discussion last year on the differing approach by NBs in relation to hydrotest pressure (Code or PED) and am waiting with bated breath to see what develops as we get further down the path.
