thermal tubing
« on: August 28, 2007, 10:21:46 AM »
Is there a type of tubing where the plastic is thermally conductive?

eg., having the tubing coiled in a hot aqueous solution and getting the heat from the solution transfer to the colder air being pumped through the tubing

Does it have to be plastic?
The only stupid question is a question not asked.

I was thinking the same  -  copper pipes might work.
Tonight I’m going to party like it’s on sale for $19.99!

Material of Shell and Tubue Heat Exchanger
« Reply #3 on: March 25, 2009, 11:15:31 PM »
I have same problem, now I am designing shell and tube heat exchanger for cooling, shell side will service demin water and tube side will service seawater. Material of shell is Carbon Steel ( A36 ), tube is Titanium, BUT since the budget is very limited, My bos ask me to search another alternative material instead of Titanium ( the expensive one ), recently I heard that there was material tube made from PP (Polypropilene). I think for corrosion resistance from seawater PP is good  ( resistant enough)The question are;
1. How about thermal conductivity of PP? is it effective for heat transfer?
2. I read on Book "Process Heat transfer" by Donald Q kern, that in engineering calculation, thermal conductivity of material is ignored because very small impact. Do you agree? Even for Polypropilene?


Thank a lot
