Procedure Qual. & Pressure Equipment Directive
Procedure Qual. & Pressure Equipment Directive
(OP)
We receiently received a job to fabricate some pressure vessels in accordance with ASME. We are a vessel code shop and hold procedures and welder quqlifications to ASME Sec IX. However, I am told we will have to requalify our procedures and welders under the "Pressure Equipment Directive" and have this process witnessed by a "Notifiying Body". I have no problem with this but, are their any other requirements different than or additional to ASME Sec. IX that I need to be aware of.
Any insite will be appreciated.

RE: Procedure Qual. & Pressure Equipment Directive
I am sure that if your procedures and qualifications were to code and witnessed by an independant third party then you will not have to re-qualify.
From what I remember the regs were applicable above a certain pressure to ensure that operators have things manufactured properly and then have in place a written scheme of examination for in-service inspection prior to start-up.
Some of the plants that had equipment in place when the regs were introduced (in the early - mid-nineties I think)
had problems meeting the requirements.

If ASME IX is used , I would suggest to add RT , PT , hardness test and macro etch in order to bring it in line with European qualifications ,although some NoBo' s accept just ASME IX as it is.

Indeed, your welding has to be witnessed and approved by a NoBo or recognised third party. Most Notified Bodies will accept ASME IX PQR's and WPQ's.
BUT,
please note that the PED is a legislation and not a code or a standard. This means that all the relevant essential safety requirements of the PED have to be filled in by using a standard, but just using ASME is not sufficient to comply with PED (f.e. performing risk analysis, etc..).
the best way is to consult a Notified Body (there is a list available on the PED website http:\\ped.eurodyn.com). Do not hesitate to do this, because it is quite complex at the beginning and if you do not comply with it you could have problems starting up in Europe.
