ABSTRACT:
A vertical tube heat exchanger having a shell enclosing a bottom tubesheet, a top tubesheet in parallel, spaced-apart relationship to the bottom tubesheet, and a plurality of spaced-apart parallel flow tubes extending between the top tubesheet and bottom tubesheet includes liquid distributor devices inserted into the open top end of the flow tubes. The distributors are fabricated of an elastic material of sufficient resilience to sustain deformation circumferentially of the distributor device to accomodate irregularities in the tube wall at the top end creating a continuous uninterrupted peripheral seal at the interface of the distributor and tube wall at the open top end when inserted in the tube open top end, and to recover the original peripheral size and form of the distributor when the distributor is removed from the tube open top end.
