Abstract
A spacing arrangement for tubes of a reheater or superheater tube section uses a spacer bar that is sufficiently long to span a space across a plurality of tubes in the tube section. The spacer bar has a plurality of holes therein which are spaced apart by a selected spacing corresponding to a desired spacing between the plurality of tubes in the section. A plurality of sleeves is provided with one sleeve on adjacent tubes in the section. A tab is fixed to each sleeve and extends outwardly from the sleeve to which it is fixed so that the tabs of all the sleeves extend outwardly from a common plane containing all the adjacent tubes in the section. The tabs extend into respective holes in the spacer bar and fillet welds fix the tabs to the spacer bar adjacent the holes and at a location spaced from the sleeves.
