I would like to share a very good video on how to make a shell and tube heat exchanger. Before, this I never know how a shell and tube heat exchanger was made. I have 2 big shell and tube heat exchangers in my plant and it is very interesting for me to know how it they are created. The video is 2.58 minutes length and it shows a small shell and tube heat exchangers. It is a straight tube heat exchanger (one pass tube-side) and it has 2 baffles. Check it out...
