Pressure Equipment Directive
Pressure Equipment Directive
(OP)
Hey Everyone:
I had a question regarding vessel construction in Europe and the various construction codes.
Does Spain recognize ASME to be in compliance with their Pressure vessel requirements?
Sorry if that seems vague, but I am curious if I construct a vessel to ASME Div. 1 Standards if it will be accepted for use in Spain?
Thanks!

If you isntead designed/constructed the vessel to PD5500 instead, would you bypass these additional hurdles? Also, what is the equivalent to an ASME stamp? Is that the CE thing I have read about?
RE: Pressure Equipment Directive
However, there are certain rules that are considered "Harmonized", so, if you use them as your design code the compliance with PED is considered as fully done.
EN 13445 is an harmonized code.

Alsdo: You should be aware that each country in the EU has implemented the directive into their own laws. There is deviations in almost every country - and these deviations should be observed.
With regards to construction: The "Easiest" methode today should be to construct according to the harmonised stadard e.g. EN 13445 or EN 13480 (that would be methode 2). Methode 1 would be after e.g. ASME or PD5500.Methode one requires a verification that al major safte issues has been considered.
Heres a short list of comon hrmonised standards:
• EN 12953, Shell Boilers
• EN 12952, Water Tube Boilers
• EN13480, Industrial Piping and Pipelines.
• EN13445, Unfired Pressure Vessels
Best regards
The CE mark is added to show that the vessel is in compliance with code. The manufactor can add this himself - but it has legal consequences to do so!

With regards to PD5500: It appears not to be easier than following ASME

The comment was made that all laws must compy with the European Pressure Vessel Directive. What exactly is the directive? Is it a design document or just a "code" that says your vessel will meet the following standards....
What is the difference between PD5500 and EN 13455? I have not seen the complete 13455 document yet but looking at PD5500 it is pretty thurough for fusion welded pressure vessels.

Look here for some explanations: www.bindt.org/downloads/PED20.doc
Or enter 97/23/EG at Google. You will get many results.
Are you from US? There are some US vessel manufacturers who have approval acc. to pressure vessel directive. So, I assume there are authorities in the US for approval.

You make have your day in he court - but who would like to be the test case?
Check with the Spanish implementation!
PED is a "directive" or a "regulation" not a code/standard. Thats EU slang for someting that eacj country should then make into a (set of) law(s) mimiking the words in the directive (since the directive has no legal meaning in each member country).
PED covers all pressure containing equipment (with some exceptions) with a MAWP higher than 0.5 barg. The exections are pipelines, house heating, pumps, compressors, internal combustion engines and turbines, pneumatic/hydraulic actuatiors and engine air intake and exhaust systems (including muflers).
The CE marking places full responsibility on the maker of the items covers by PED (this resposibility cannot be transferred to e.g. a verifying body).
In each country there will be a "National authority (in Denmark its "Arbejdstilsynet" - they do NOT verify equipment or installations. Then there can be a number of "Notified bodies" (NoBo) each identified by a four digit no - these companies will make a verification. The involment of the NoBo depends on wich modules that are relevant for your project.
As it has been said: Take a look at PED yourself - you will see that
-PED will not tell you how to construct the vessel
-PED will give some mandatory technical safety measures
-PED does make requirements for QA systems to be in place
-PED also has requirements for modifications and repairs of systems build before PED

The annexes (especially I and II) are also interesting. Look at annex II for how to categorise your equipment/installlation and how to select QA module.

I have been able to locate a reference in guideline 6/12 - but thats not a stricly positive one.

We might not find an agreement but beleive me: A pressure vessel which is manufactured in Spain acc. to the Pressure Vessel Directive 97/23/EG must not be rejected by a Danish or French customer unless additional (!), specific application rules were not considered. The purpose of harmonized standards within the European Community is to avoid that this happens. You are right that each country has to turn a directive into national law but the national law must not disagree with the European directive. I'm European and we supply pressure vessels as a part of our equipment.
Right, CE marking is something the vessel manufacturer does. The manufacturer puts the CE mark on the vessel and issues a Declaration of Conformity with all legal consequences. From a certain size and pressure on a notified body must check the calculations before manufacturing and the manufactured vessel itself. This notified body issues certificates which must be supplied with the vessel. These certificates are mandatory to take the vessel into operation (this step must be approved again) and for the periodical examination of the vessel.
The problem for jgibbs22 is to find the corresponding category his vessel is subjected to.
Legally ASME is not recognised as an approved code of construction under PED. That's for sure. And an ASME stamped vessel must not be market in the European Community without CE marking. Whether or not an additional approval by a notified body is nececessary depends upon the size and the pressure of the vessel.
