Tried finding on google but couldn't trace out.

Thanking you

Do you have any info? A Spec? A product form? A Tradename?
I can guess, but that isn't what you want.

The only thing I have found in the ASME Code is in ASME Section II Part B, SB-171 which covers CuZn38Sn1.

I didn't find anything regarding the two others. May be they aren't approve.

Go to Copper.org ans search there. The CDA has all things copper based.

@IdanPV & @0707, thank you so much your replies.

 

[EdStainless]

And it is a European drawing? You may have to go back to an old version of the code for some of these materials.

@EdStainless,

Yes, the drawings were preapred by a fabricator in England and later tube bundle was replaced by a german fabricator.

In my opinion, the nearest equivalent your materials are following this:
- CuZn28Sn3 : ASME SB 111 C4 series (C44300 / C44400 / C44500
- CuZn38SnA1 : ASME SB 111 C2 series (C23000 / C28000)
- CuZnA1 : ASME SB 111 C6 series (C60800 / C61300 / C61400 / C68700
