PED Question: Claiming Sound Engineering Practice 2

[Vidaman]

We manufacture a couple of small cast aluminum pressure tanks that we are looking to sell in Europe. Both tanks fall under the Sound Engineering Practice article of the PED. The tanks are so old that we have no design or qual test documentation, only drawings and QA inspection test results.

Without having to wade through all of EN13445 or ASME VIII-1, what is the most expedient route to creating a technical file for these tanks showing SEP? I have been unable to find anyone that can say "For your tank, you need to calculate this and test to spec XYZ". The thought of looking through 712 pages of the EN13445 design spec alone is making me nauseous.

Thanks in advance,

-Mike

As far as we are concerned our notified body (Lloyd's Register) has advised us that for SEP items you do not need a technical file and you don't have to put a CE mark on them.

Vidaman,
What Lloyds Register should have told you is that for SEP Equipment you are NOT ALLOWED to put a CE mark on them rather than "you don't have to".

maxh and DSB123,

First, thanks for the input. Second, do you know of anyone (i.e. consultant) that can help determine if these tanks comply with EN13445? Right now we have no calculations or test data and feel it would be prudent to confirm that we meet the requirements of EN13445 prior to selling these tanks in Europe, even if a technical file is unneccessary.

Thanks again,

-Mike

Contact COADE who offer their CodeCalc and PVElite software. I believe they are contamplating include EN13445 in their software.

Raydel,
Whessoe Technical Computing are not just contemplating including BS EN13445 into their PVE5 software but are busy doing it NOW. It should be incorporated later this year. PVE5 will then cover PD5500, ASME VIII and EN13445.

RE: EN13445, CODEWARE: THE HOME OF COMPRESS, AND OTHER SOFTRWARE VENDER IS INCLUDING THE EN13445 FOR THE NEXT RELEASE.

Fawkes,

I'm basically doing what you've outlined in your message. We are drafting our own test specification that will address all the key design points of the vessel using ASME and EN requirements as a framework where applicable.

We are using the Hazard Assessment to guide development of both the qualification and continuous conformance test spec. The Cat. I and SEP tanks will be treated equally in this regard. We have also consulted with a Notified Body for their guidance.

You have confirmed for me that I am on the right track. Many thanks!
