ABSTRACT:
The water wall fit up tool will fit a wide range of tube panel sizes such as ⅞ inch through 3¼ inch tube sizes. It uses the adjacent tubes to force the tube panel into alignment. One unit can fit up two tubes yet can be used in conjunction with two or more tools. The water wall membrane keeps the tubes rigid and the portion of the tube panel where the membrane has been removed allows for movement.
