How To Make A Shell and Tube Heat Exhchanger

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...

For 2-4 pass heat exchanger what is the correct formula for calculating Ft factor (LMTD correction factor) ? I tried using the formula given in D. Q. Kern but I am not getting correct answer there seems to be some error in the formula.

Pls advise

Manohar,

I'm on my weekend break. Allow me some time to check on this matter. I'll get back to you asap.

Very interesting! I always like to know how things are made. The tubes are welded to the baffles. I wonder how they make heat exchangers that can be completely disassembled for cleaning off scale and then reassembled again.

I think they just clean using a high pressure jet pump water to clear the scale in the tube. In some cases they add a drill in front of the water jet.

Analytical Solutions Sdn Bhd Malaysia actually sells a tremendous cleaner ( descaler) for cooling towers and boilers. Its revolutionary . For cooling Towers it will make subcontractors redundant. and for boilers the cleaning is great as it does not corrode the metal surface like how many chemicals do.
