We required that the stub tubes be replaced, and that the tubes be heat treated after welding works (PWHT). Then it will be checked by Phase Array UT, MT, and PT. Make repairs based on the result.
The contractor only required for the supply of new tubes.
We planned to implement the replacement...
Hi,
I would like to inquire if when are we gonna apply hardness test for boiler pressure parts. We will replace final superheater stub tubes (SA213-TP347H).
Good day.
