Dear Sirs,

Project: Coal fired power plant ASME B31.1 CODE

We received a pipe material 1 inch dia with a material of A335 P91.
This material had been welded.
During operational, 2 years after, one pipe burst out.
We send for testing to check the chemical composition. Please see attached docs.

I checked on ASME Section II Part A and it was very far from the chemical requirements of A335 P91.

My query is that, what kind of pipe material base on the result of test report.

Your reply to this query will be highly appreciated.


Regards,

Mac
