Welcome to the forum.
ASME materials are adopted in sec IIA/B, which are generally used in BPV code. B31.3 allowable stresses are listed for ASTM materials. If you select ASTM materials, pl check applicable year of edition&addenda, equivalent ASME listed materials can be found on respective code with year of edition/addenda.
Similarly, others like API (American Petroleum Institute) can be found in API 5L standard. These are similar to ASTM/ASME, but neither is superior to other.
No restrictions to use these materials as long as your designer select them based on their allowable stresses.

Subject: [MW:5271] Process pipe work
Dear All,
I am a young guy having strong desire to learn something in welding.I
would like to clear some of my doubts through this forum.Please don't
curse me or ignore my query if you feel it foolish as I don't have
much experience like my seniors.
Dear all,
I am working in a small process pipe work based on ASME B31.3
code.Here which material code we have to review,ASTM series or ASME
BPV SEC II Part A (Ferrous) Part B (Non ferrous)?As far as I am
concerned both looks same !!! If any dispute comeup which one has the
upperhand(Has the capability to supercedes the other). More over I
couldn't find some of the materials in ASTM and BPV SEC II Part A or
B. But they are listed in ASME SEC IX (Eg. API 5L grades).Is there
any restrictions to use these materials for process pipe work?
Thanks and regards
Limesh
