ABSTRACT:
A heat exchanger (1) has a plurality of fluid flow tubes (5) secured adjacent their ends by tube sheets (6, 7). Cleaning elements (18) are adapted to shuttle back and forth in the tubes and are adapted to be captured by elongated slotted baskets (17). A cleaning element retaining device includes inwardly extending pairs of projections (30, 31) integral with the basket and with the respective pairs being offset longitudinally along the basket axis. A cleaning element can be tiltingly manipulated past the pairs of projections for insertion or removal into or out of the basket without substantial damage to the projections.
