Dear Experts,
We have one of our fin fan cooler leaking from tube to tubesheet joint. The tube material is Duplex stainless steel.
We would like to carry out re-expansion of the tubes, your advise is needed for %age expansion allowed when these tubes are to be re-expanded. The tubes are in operation since last one year in Sour Water Recovery Unit ( H2S service).
Also if some body can share their experience in case of leakage even after re-expansion how to repair the tube to tube-sheet joint. For information the header is welded constuction.( Ref attached file )
Thanking you,
Vinod
