BROWN FINTUBE Hairpin Heat Exchangers - In general, the bundle of a hairpin exchanger is removed by first removing the tubeside bolting, flanges, and split rings. The next step is to remove the shellside bolting, flanges, and split rings. Finally, the return bonnet bolting is removed and the bonnet is placed to the side. The tube element can now be pulled from the back end of the shell by placing a sling around the U-bends. On larger multitubes, a plate is installed around the U-bend for proper sling placement. Assembly is performed by reversing the process and utilizing new gaskets.
