Water-cooled pipes (16, 18) of the type utilized to support steel workpieces in reheat furnaces and the like are insulated by preformed, rigid refractory members (30). Threaded studs (40) are welded to opposing surfaces of the pipe (16, 18) or the web (20) between a pair of pipes. The pipe(s) are then covered by a ceramic fiber blanket (44). A pair of the refractory members, each of which contains an aperture (46) through which one of the studs is received, is positioned so as to cover the pipe(s) and blanket. Nuts (50) are fastened to the studs to hold the refractory members in place. The refractory members are sized and positioned so that gaps exist between them so as to allow for thermal expansion. These gaps may be filled with blanket insulation or heatresistant plastic. The remaining portions of the apertures are also filled with heat-resistant plastic. |
