: Tony, you are going to have to provide a great deal more information to even wager a guess. What type of HRSG, what is the accessiblity to the failed tube, what is the failure mode, what type of repair... etc.
OK.
I'm thinking of a large utility size HRSG, triple pressure with reheat. If module location makes a difference, I would be interested in how the price varied by section. As far as accessibility, one that is deep in the bundle where multiple tubes would have to be cut. The failure would be at the tube header weld from stress corrosion cracking. As far as I know the only repair they would do in this instance is tube replacement, if tube plugging or some other repair type is an option I would like to learn ballpark figures on those as well.
Even within the above parameters I'm sure there are still a lot of factors in the pricing and large variance. I'm just looking for a rough estimate, or even better, a range of possible figures.
Thanks for the response.
