SS Tube Heat 1

[bzn]

Could anyone can give me a details in terms of material composition and any supporting doc on:

A 213 TP 347 AND A271-347

It is true that A271-347 already discontinuity and been replaced with A213 TP347?

The answer to your first question is to go to the ASTM web site and review A 213.

http://www.astm.org/DATABASE.CART/withdrawnstandards.html

A 271 was withdrawn in 1999, and replaced with A 213.

Dear metengr.. in terms of P no and nominal composition; itis the same

 

[metengr]

In terms of P-No yes. I don't have the actual A 271 material specification for a side by side comparison with A 213.

Did you have Hx tubes supplied under A 271 originally installed? If so, the A 213 tube material specification can be used in place of A 271 provided the same Grade or an upgraded tube material Grade is used.

The chemistry will be the same. There may be a minor difference, some of the old specs didn't exactly match, but it wouldn't be an issue.
