You can use material from almost any code
If you can convince your notified body (NB)that the material fulfil the essential safety requirements (ESR) of Annex 1.The NB makes a PMA.
For the rest of fabrication the notified bodies don't have the same acceptance over Europe. It...
Has any one has succes with particular material appraisal, PMA, acc to PED. I'm mostly intrested in US materials as A-105, A-106 grB A-234 WPB etc.
Please share your experiance

Hi
what kind of welding errors is it? what does the x-ray reports say?
You must know what kind of errors there are in the weld to prevent the same happens again.
for example lack of fusion could be a result of low energy etc.

We only use SW in servicesystems i.e. water, steam, air and nitrogen.
But have problems with bad welding! Be sure that there are at least three layers of weld and absolutely no undercuts.

I need to collect some experience around intervals and methods for inspections of coldboxes (perlite insulated cryogenic equipment) Risk analysis and maybe RBI to avoid open and emptying the boxes.
Any sources of information will help.
Thank You for information
I've just started a project where we will change to kammprofile on aprox 100 exhangers on an ethyleneplant.
Many of them quite old so we have to check and adjust all sealing surfaces
I have had success with gaskets type kammprofile and hydraulic tension of bolt. With hydraulic tension of bolt you get the same tension on all, or at least 50% of, the bolt at the same time.
