Large double pipe heat exchanger - how to connect in series?

  1. Mar 12, 2009 #1
    I have designed a heat exchanger of the double pipe hairpin variety and with 6" and 8" concentric tubes. The overall length is 90m therefore I need to connect nine 5m hairpins (10m total length) together but thinking about the practicality of it is it possible to connect this number in series and how should/could it be arranged. In series do the hairpins (U-tubes) have to be placed one on top of the other?

    Iv looked at the possibility of a parralell stream - as from the literature the general consensus is that in parralell the hairpins are side by side and in series on top of each other.

    Thanks for the advice
