Abstract
A heat exchanger having end head elements has a plurality of fluid flow tubes secured adjacent their ends by tube sheet elements. Cleaning devices are adapted to shuttle back and forth in the tubes and are adapted to be captured by basket elements. A basket retaining plate is disposed outwardly of and parallel to a tube sheet element. A longitudinally compressible device is disposed between the retaining plate and at least one of the elements to compensate for misalignment of a tube sheet relative to the heat exchanger housing.
