ABSTRACT:
A support apparatus for tubes in a U-bend portion of a tube bundle. The support apparatus includes a U-tube ring positioned around the tubes in the U-bend portion and having first and second tube separation elements extending therefrom through first and second lanes between the tubes, respectively. The first tube separation elements are preferably characterized by flat plates or strips defining a plurality of holes therethrough, and the second tube separation elements are preferably characterized by rods or bars extending through aligned sets of holes in the plates or strips. A support bar extends between opposite end portions of the ring, and the plate have notches therein for engaging corresponding notches in the support bar and ring. The ring and support bar are slidably attachable to a mounting bracket on a tube support used to support a first and second pass of longitudinal tubes in the tube bundle. A method is disclosed for fabricating the U-bend tube support.
