Abstract
The hydro-blasting anti-withdrawal device support is used for mounting an anti-withdrawal device (AWD) utilized when cleaning heat exchanger tubes in a shell-and-tube heat exchanger where the tube sheet is recessed within the shell. The support includes a shell flange attachment plate, an AWD attachment plate, and a pipe spacing the two plates apart. Each plate is substantially rectangular and has a pipe attachment tab extending therefrom, the pipe attachment tabs extending in opposite directions. In use, the shell flange attachment plate is secured to the shell flange, the anti-withdrawal device is secured to the AWD attachment plate, and the pipe is dimensioned to support the AWD in close proximity to the heat exchanger tube sheet.
