Title: thermal tubing
Post by: BritClaridge 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?

I was thinking the same  -  copper pipes might work.

Title: Material of Shell and Tubue Heat Exchanger
Post by: rofik_nurhidayat 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
