Foreign materials ASME certification?

Foreign materials ASME certification?

Foreign materials ASME certification?

(OP)
Under what conditions can foreign materials be used as ASME materials? Is there a procedure to certify European steels as ASME materials?  

RE: Foreign materials ASME certification?

What section of the code are you using? If this is for a section VIII pressure vessel, then UG-10 is probably what you're looking for. If this is for piping, I think it's easier; if this is for nuclear vessels, then it's harder.

RE: Foreign materials ASME certification?

easier? it is not. If the material spec is not listed or it has been approved by a code-case, then you will need a code-case approved. UG10 does not cover
materials to other specification or forein materials.
 

RE: Foreign materials ASME certification?

GenB - I don't think the OP is so much looking to use an unapproved material, as he is looking to certify/dual-cert a foreign material as one presently listed under ASME.


rauval - Can you please clarify whether you're looking to use an unlisted base material, or whether you're looking to have a "foreign" material certified as one of the listed grades?

GenB,
I am looking to use a foreign material, unlisted in the ASME code, but listed in the German PV code, for the fabrication of an ASME pressure vessel.

RE: Foreign materials ASME certification?

You need to get the foreign material adopted by ASME per Section II Appendix 5, or get it dual-certified to an ASME specification per UG-10. See page 4 of this ASME newsletter:
http://files.asme.org/asmeorg/Codes/CertifAccred/Accreditation/1030.pdf

In response to GenB, I must confess that I am not very familiar with piping codes. However, I noted that ASME B31.1, paragraph 123.1.2(A) permits unlisted materials as long as they are made to a published specification, not necessarily ASME. So that sounds easier to me. That code also allows non-metallic piping, which is never allowed under Section VIII.

 

"My tube socks were designed and fabricated in accordance with the intent of the code. They're just not stamped."

trottiey,
thank you for clarifying the adoption process for me. This is exactly what I needed.
