Dear all,

Would please advise me what is the main difference between ASTM material and ASME material. Can ASTM material be used on pressure vessel? Please show me where on Code I can find such regulation. Thank you so much.

Jeff,

Read the Foreword of ASME Section Code Section VIII-1 2010 Edition. ASME material specifications approved for use in each construction Code are listed in the Guidelines for Acceptable ASTM Editions and in the Guidelines for Acceptable Non-ASTM Editions, in Section II, Parts A and B.

Thank you Leem,

I learned, I really appreciate you assisstance.

All the best

Jeff

A further question, if the Material Test Report is only comply to ASTM, i.e. A516 Gr.70, can that material use to construct a ASME PV?

klchoo,

The subject material is A516-70 is listed in the Guidelines for Acceptable ASTM Editions In Section II Part A of ASME Code.

Leem817, thank you for the swift reply.
My concern is will Authorized Inspector rejects the MTR if the equipment has to construct strictly in acc. to ASME BPVC?

klchoo,

In my opinion you will be in compliance with the Code, however if your AI rejected the material in question then I will ask him what is the basis for rejection.


leem817

Typically, the lack of the year of edition of the ASTM spec in the MTR. In which case you quickly call the quality dept at the steelmaker, they give you the most recent year of the spec that they have. Of course, it's newer than the range in the book. Now you have to buy the newest from the allowed range and the one which the material is certified for compliance with (luckilly it doesn't take a lot of time, just a fistful of bucks). Now you have to review them for differencies, and if your AI is extremely stubborn, recertify A516 to A516. This would not be based on ED-1, but on UG-10. Different approach, different piece of paper to be produced (where the heck is the form in your exhibits section of the quality manual?)- can take a lot of time. Hope it's not during a Joint Review and you're not dealing with an Inquisition-like guy...

Suppose the year of ASTM is latest and the latest edition is yet to be adopted by ASME , the plate can not be used. Is this contention true ?

And this is how we get quality product acceptable to Code.

Or may be we can wait till ASME adopts the latest edition and then it becomes acceptable.

True. It cannot be used on basis of ED-1. But it can still be used on basis of UG-10, after proper recertification. To be able to recertify, you physically need both specs to review them for differencies. This things should be done before the material is bought, otherwise you may find yourself in... you know, in trouble
Sure you can wait. But will you client wait?

Dear all,

Do we need to punch any marking for the astm material for asme material..

eg. we buying a105 for the flange. but the vessel using is for asme u stamp. do we need to put sa105 marking onto the flange instead the ready made marking a105??

Thanks in advance..

You are touching a peculiar argument. Flanges per ASME B 16.5 are permitted to be used in Sect. VIII. But B 16.5 specifies ASTM material, so ASTM for B16.5 flanges is perfectly suitable. Read B 16.5:
5 MATERIALS
5.1 General
Materials required for flanges and flanged fittings are
listed in Table 1A with the restriction that plate materials
shall be used only for blind flanges and reducing flanges
without hubs. Recommended bolting materials are
listed in Table 1B (see para. 5.3). Corresponding materials
listed in Section II of the ASME Boiler and Pressure
Vessel Code may be used provided that the requirements
of the ASME specification are identical to or more stringent
than the ASTM specification for the Grade, Class,
or type of material.

Mind the joke about ASME (Always - Sometimes - Maybe - Except)

Hi, this is regarding the use of ASTM material in division 1 vessel.

We are designing a vessel for PED compliance with ASME design code. The end application is pharma-base and hence tubes are mostly used for piping. Thus my problem lies with nozzle tubes. The product requirement is for sanitary tubing as per ASTM A270 which is not listed in Table ED-1 of Section II. The allowable stress value can be calculated as per PED norms (substituting 0.2% proof strength for 1.0%) but the question remains that can we use this material for Section VIII Division 1 vessel and if so is it OK to use the PED stress value in calc. I got some suggestion to look into UG-10 but i couldn’t figure out head or tail of it.

Can anyone please elaborate?

Material for which allowable stress is not in Sect. II/D cannot be used.
Mauro

Yes, it can. It's all about what "used" means, what "cannot" and so on. But believe me, I have used materials and you wouldn't find them in SecIID.
