ASME to PED 8

[dcasto]

as usual I always get the tough problems, well at least in my area.

A collegue has a cliant in Ireland that is interested in buying a new surplus packaged gas treater in the US and ship it to Ireland.

The packaged unit has pressure vesels and piping. The original U1A's and MTR's are available. welder test reports and all inspections and hydrotest are included.

Is there a company, consultant, process, red taper cutter, bribe (ok not really ethics is still a priority), but a legitimate process that would transfer the ASME code vessels and piping to PED?

First of all I would check in which category of the PED directive your item is.
The following link offers a free tool, that identifies the category on the basis of some data.

You may or may not need the aid of a notified body to comply with PED prescriptions, and this depends on the category your item is.

Please remember PED is not a design code.

Maybe Lloyds or Det Norske Veritas.

You can also ask the customer what no(tified)bo(dy) they contact for these issues.

You might want to look at thread404-265072, which is asking much the same question.

The way I've read the responses there is that PED is more akin to the American "Code of Federal Regulations" in that it sets down legal requirements.

While you might be able to use an ASME designed vessel to meet the requirements in both cases, just saying that something is designed to ASME doesn't ring all the bells and blow all the whistles.

I haven't heard of any legitimate process to transfer the ASME code vessels and piping to PED. Ask your Irish client for nodified body in Ireland. I think that is the easiest way although Lloyds and Norske Veritas are both a good advice. A notified body will also help you to find the correct category for your vessel (they get paid for that).

There are nice pubs in Ireland, David
You've got a nice trip ahead,
I'm jealous.

micalbrch,
Just for clarity - it's the manufacturer that catagorises his equipment - not the NoBo(he does not get paid for that). The NoBo just ensures that the pressure equipment complies with the PED (if it's in NoBo territory)

 

[europipe]

It's easy to determine the category.

DSB123: The NoBo does not have to help, but a good NoBo will. I did not write that NoBo must catagorise the equiment. I wrote that they will help. That was perhaps misunderstandable. Sorry for that.

 

[dcasto]

thank you all very much for your help.

dcasto,

Royal & Sun Alliance or TUV are the favoured NoBo's in Ireland if you need them.

For any category above SEP (Sound Eng Practice), the chances of getting something built to ASME approved to PED after the fact are slim... The welders need to be approved to PED procedures, the mfr's quality system needs to be approved by the NoBo, the materials have to be accepted under PMA (Particular Material Appraisals) which have more stringent requirements than ASME, etc.

MrBTU,

Quite hard for a pressure vessel to be under article 3, paragraph 3.

 

[abbver98]

I want to put some clarifications for equipment coming from outside EU. I'm in the same situation. I import some coils built according to ASME and as I know my notified body very well I told to for final examination (equipement Cat II, module A1). Unfortunately the mtrl certificate and some welding quality issue make the examination very hard. We tried to make mechanical tests to have 3.2 certificate but after investigation the supplier of components founded to be ISO9000 to PED. For the quality of welding I repair and retest. In final you should involve the notified body from the begining. Now I'm ordering pressure vessels from US and I ask the notified body the approval of document at each stage (stress analysis, material certificates, traceability transfer procedure, PQR, WPS, ASME inspector involvement, NDT operator qualification, hydrotest procedure , PMA...). So I recommend to involve the notified body from the begining. Some are EN standard oriented and they swere only on EN standard so they don't accept pqr according to ASME IX without additionnal tests. Other are more flexible and tried to find solution to meet the PED requirements.
Good luck.

 

[MrBTU]

Ione,
We've built and shipped many pressure vessels under article 3, para 3.

Depending on what PED categories the vessels are in, the original manufacturer would need to provide the CE marking and declarations of conformity (to the PED).

The best chance of success is if the inspector involved in the original manufacture and testing was also a Notified Body. I don't think the NoBos in Ireland would want to take this on. I tend to agree with MrBTU - the chances of achieving PED compliance after the fact are slim indeed.

If you managed to find a way down the certification trail, then the vessels would still likely require rehydrotest, as PED requires 1.43 x Max Allowable Pressure as a minimum. That would be the easy part though.

Cheers,
John

Mr. Btu,

I didn’t say it is impossible and if you usually do, I believe you. Anyway speaking of non-dangerous gas (group 2), it requires Ps*V<50 to be under article 3, para 3 (table 2). Just to make an example a vessel with a max. allowable pressure Ps of 1 barg must have a volume V < 50 litres.

 

[DSB123]

JohnGP,
You say that a the PED requires a hydrotest of 1.43x Max Allowable pressure as a minimum. The plant being to ASME would have required 1.5 x MAWP so testing is covered (i.e. 1.5(i.e. ASME) > 1.43(PED))

 

[JohnGP]

DSB123,
My apologies, I assumed the vessels were built more recently under ASME VIII requirements that insisted on 1.3 x MAOP. If they are much older, then I would guess that getting PED certification would be slimmer than slim.

Cheers,
John
