We have inspected a tube bundle using RFT, and the output was the remaining thickness of each tube, how can I determine the tube remaining thickness below which I would plug the tube? Thanks,

Air coolers are finned tubes, and the article states that the article is only for shell and tube, not other type.

Thanks for reply, But the mentioned article in PCC-2 is for shell and tube heat exchangers. Thanks,

Hello everyone, As we know, in ASME PCC-2, we can find the inspection and repair techniques for shell and tube heat exchangers, where can we find the same for fin fan air cooler, to choose the number of tubes to be inspected, and the repair methods. Thanks,

Hello, Why in ASME b31.3 calculations we use "Allowable stress", while in b31.8 the Specified minimum yield strength SMYS is used? Thanks

I mean: In ASME Sec II Part D, Why in table 1A, the temperature limit is specifically (-30C)?

Why in asme2, table 1A, the temperature limit is specifically -30C? And if i want to use a value of S in a lower temperature, which code to get it from?

If all components of the vessel is accepted, but the flange is severely corroded, how can i evaluate its acceptance?

Hi all We have a pressure vessel with attached nozzle connected to WN flange, the flange is externally corroded tha the thickess of the flange reduced by about 4mm. What is the acceptance criteria of the flange dimensions reduction by corrosion? Regards,
