Use of EN material certificate on a designed ASME+PED boiler 1

[lgracio]

If a boiler is designed, manufactured and tested in accordance with ASME section I plus the PED, I am authorized to use a EN material with a material test report only properly certificated to the standard specification EN10222?

According ASME-I (PG-7.2 and PG-9.1) edition 2015, the SA/EN10222-2 have been adopted by ASME section II - Part A.

This case is for a pipe with the material specified by designer of SA-182-F22 CL3 (PMA - ASME+PED) but the material I want to apply on manufacturing is 11CrMo9-10 that is handled by a CMTR certificated according to EN 10222-2 only.

Any problem not having dual certification EN and ASME?

If the vessel is not stamped per ASME I, I see no real problem. If it is to be stamped, check with your AI first then check with your AIA.

The simple and short problem; no problems with dual certification (or even triple or quadriple or ...). You may use the EN 102222 material under ASME I only if the specific grade for EN 10222 which you need, is listed under ASME II-D. EN 10222 does fall under ASME II part D, but is grade dependent. I assume you mean EN 10222-2 1.7380. This equals 2.25Cr–1Mo. It's listed under II-D and thus allowed under Sec I. You thus dont even need A182-F22-Cl.3.

On the other hand. If your boiler falls under stamping jurisdiction, you need to check with your AI as weldstan mentioned. Especially for countries like USA, CA, etc.
However, as you mention PED, I assume the jurisdiction here is the European law, rather than US or Canadian (or whatever). As such, the Essential Safety Requirements need to be fullfilled. In that case, the approach is different. Now you need to show compliance with a directive rather than a design code. In such cases it's easiest to use harmonized standards like EN 12952 or EN 12953, as they have presumption of conformity with the PED.

Many thanks to you both weldstan and XL83NL.

You both are having the same interpretations as I did, I just want to make sure I'm doing right interpretation.

The boiler is not requiring ASME stamp, but in other side is requiring CE Marking (ASME+PED) at the site construction/commissioning.
In fact the material specification I got from project design has a PMA of SA182F22CL3 requiring Pressure Equipment Directive2014/68/EU compliance, and I've made the analysis of specific CMTR (EN10222-2, X11CrMo9-10) that is in accordance with PED annex I requirements.
I'm not sure if the material certificate must acknowledge the SA/EN10222 as per ASME section I, in fact is only saying EN 10222-2.

The forged round bar X11CrMo9-10 is used to replace a small pipe of 200mm, 2 1/2" SCH 160 specified as SA182F22 CL3. Need to machine forged bar to have pipe in the end for a small branch connection and butt weld to another pipe.

Conclusion: ASME Stamp is not required, than since ASME-I, PG-9.1 the SA/EN10222 is adopted to the ASME II-D, then the material CMTR with EN10222-2 can be applied to the PMA from design specification.

Hi
i am not familiar with Sec 1, but since i have found the basic rule for designing a pressure vessel or a boiler the same, UG-10 in Sec8 Dev1 may be useful as a guidance.

Hi Alireza Moein, thanks for guidance.
I see like in Section I PG-9, you can find the same on Section VIII div 1 UG-4. As per the same assumption, since material is adopted by ASME II-D it can be used for such limitations and restrictions as described. Check the ASME II-D table 1A, if material SA/EN10222-2 is included then is acceptable.

Thanks.
