Adopt an ASTM Material for use in ASME 1

[Seeker88]

Hi folks,
Our company is well used to checking through certification of ASTM materials for ASME U Stamp applications. However, my question is as follows;

Our client wishes to utilise ASTM A270 tube for a polished heat exchanger. He could get the material dual certified to ASTM A269 (the mechanicals and chemicals match etc). However, neither material grades of 269 or 270 appear in section IIA of the Code.

What would I need to consider to adopt these materials? It is not a U Stamp application but I still need to ensure I am working to the intent of the code etc.

Thank you in advance for any assistance you may be able to offer.

Typically A269/A270 tubing is also certified to A249 just for this reason.
Neither A270 nor A269 have mandatory tensile properties and mandatory 100% NDT.

This isn't from a US mill is it?
You could try CC, but they will likely tell you to use A249 along with A270.

Just a thought ... Isnt A270 heavily used for BPE applications? Doesn’t BPE work together with other ‘main’ construction codes like B31.3 and VIII-1, and could provide some basis for a CC?

All of the BPE tube that we ever made was dual certified SA249/A270.
