Non ASME materials
Non ASME materials
(OP)
Friends,
I'm designing a D-Type Water tube boiler Acc. to ASME sect I ,Ed.2004.
For lifting lugs,external attachments etc. I want to use St37-2 DIN material.
Our AI say material must be ASME material.But St37-2 is not ASME material and since these parts are non pressure parts(please someone can clarify me what is the pressure and non pressure part? Are attachment plates pressure part?)I think, material of these attachments are not inspectors' scope but weld of these ASME and non-ASME material and its WPS and PQR's are his scope.
For strips(fins) to be used on panels(boiler pipe walls)also in this scope he says.Are strips and their materials are ASME scope or not?
I'm a little bit confused about it ,is there anyone can help me?

RE: Non ASME materials
I would obtain either a Certificate of Conformance or Material Test Report for non-ASME material for the AI to review because you need this to qualify the WPS.
RE: Non ASME materials
Materials will have EN10204(2004ed.) 3.1 certificates. Acc to your reply it must not be ASME material.Am I misunderstanding?
RE: Non ASME materials
Change the must to may in the sentence above. Now, you understand.

SA36 is an ASME Material, can it be used for Lift Lugs?,
Can it it be used as metal backing on welds for pressure parts?
in a Sec I Fired or unfired?

Reply; yes
Question 2;
Reply; No. If you review PW-5.1 of Section I, Part UW, it states that materials used in welded construction shall conform to one of the material specifications in Section II with allowable stress values. Well, SA 36 does have allowable stress values but you must read further that Section I limits the use of SA-36 to bar stock and for use as stays - See Section II, Part D notes G15, G18.

deanc regardless, if the Code does not allow it! you can not use it.
MTR's are CMTR's and they are suppose to be by the Mill or the AI will beat you.
Any idea of acceptable materials.
By the way: All the Shops use SA36 for lift-lugs because of the "structural" quality; what can you say about that,
also attachments on boilers are SA36 (external non pressure parts or internal non-pressure parts)

VIII-1 accepts SA36 FOR construction,, we are talking Sec I here, which prohibits it.

Thanks for pointing that out to me. See PG-55.2.
What I was getting at was perhaps one wishes to install sheet metal baffles,say A-1011,has them cut and formed at AL's SheetMetal. Many times this stuff arrives with paperwork from a supply house only. You should take the extra effort and get MTRs from the mill. They do not have to be CMTRs,or signed for that matter.
