Tube expansion procedure
Tube expansion procedure
(OP)
We manufactured a removable u bend heat exchanger. For the expansion of the tube. We received a last minute info from our client that the tube weld joint cant be expanded. Which means the expansion starts few mm from the face of the tubesheet, and the first few mm(4~5mm approx) of the tube are unexpanded. Nobody in our organisation had ever heard such thing. Usually we just expand the whole length of the tubesheet thickness. I check the TEMA requirement and found no such thing. Did anybody here know any reference to relevant codes indicating this kind of requirement???
