Code Accreditation for Mills
Code Accreditation for Mills
(OP)
I am trying to find an ASME publication describing the process by which a material manufacturer is granted and retains approval to manufacture and apply the required marking to product forms such plate, tubing, pipe, flanges, bolting, etc.
My company is involved in a paperwork snarl of epic proportion in attempting to certify some of our little piece-of-crap, but ASME stamped, air coolers to a shipboard standard. The agency involved classifies these coolers in such a way that design review is not required, but materials to approved specs from approved manufaturers are required.
These coolers normally are built from stock ASME materials. We are trying to be granted a deviation by proving that the ASME accreditition process is equivalent to the process used by the involved agency, and together with MTR's to persuade involved agency to accept these materials.
We cannot of course just purchase from the approved manufacturers unless the material in question is certifed to ASME as well as the ship standards, which I doubt it.
Anybody know of which publication applies?
Regards,
Mike

Perhaps a particular Code Section or publication/paper giving guidance as to the use of alternative materials acceptable to ASME? Perhaps like the following link: http://files.asme.org/asmeorg/codes/9383.pdf

The surveyor involved has a different opinion.
Stanweld, I had sort of thought that mills must have something similair to a C of A to produce materials to ASME specs, but maybe this is not so? Are they "self insured" so to speak?
Thanks to all,

What, in the ASME world, might correspond to a DNV "Works Certificate"?
Defined as: Works Certificate (W)
A document signed by the manufacturer stating:
- conformity with rule requirements
- that tests are carried out on the certified product itself
- that tests are made on samples taken from the certified
product itself
- that tests are witnessed and signed by a qualified department
of the manufacturers.
Per DNV, this is apparently not satisfied by the MTR's.
Thanks again,
Mike

Nothing at the moment within the scope of Section I or Section VIII.

I am able to review and comment on ASME BPVC letter ballots and I have seen nothing on the horizon for this activity.
RE: Code Accreditation for Mills
So, I open a mill and make plate and forgings, say. I represent them as meeting ASME specs and mark them as such. Is there any independent oversight of my activities aside from test reports, or is it entirely on me?

For ASME B&PV Code material or even ASTM material being certified, as such, it is all based on honesty/integrity of the Supplier, and the Purchaser must source check and/or audit/police or have someone audit/police their own product at the mill. Sorry, but true. Purchaser beware!

Relating to my original problem, by obtaining and reading yet another DNV spec, I think I can see a way forward. A couple of days of "lawyer" work, and we'll see.
Thanks to all for the input.

with supporting docs. ASTM/ ASME/ISO, etc.
ASME Sect II defines all the materials mfg requirements,
includes ASTM materials. A mfr who certifies shall have authorizations to even use the names ASTM AND ASME
when materials are stamped/stencil.
There are cheaters of course who put glue to cover flange pinholes...
RE: Code Accreditation for Mills
What is your basis for this statement? Who authorizes?
Thanks,
Mike
