The problem with sloppy work is that the supply FAR EXCEEDS the demand

It seems to me that for a given service the HX will be physically larger as well, as you may need more pipes (smaller ID for a given OD)) than you would tubes and I doubt you can array them as closely as you can
pipestubes. This, of course, is guesswork on my part.But from a Code standpoint, it is permitted. It is common in waste heat boilers for one example.

What is wrong with tube?
And I should add that many times pipe is not either Eddy Current tested or leak tested, not a good plan for a HX.

Can you give us more details like size/wall thickness of tubes and pipes, tubes ASME spec? Also process data like type of fluid temperatures and pressures wouldn't hurt. It is because people need to see everything in prospective in order to give you correct answer.
By the way, are tubes and pipes are quoted by weight? What is price difference we are talking about?
Thanks,
Curtis

The tube specs in general require 100% ET and then either air-under-water or hydro.
We actually have customers that order tube to a pipe size for HX work. The original was designed for pipe but they want tighter tol and more NDT.
