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.
Claims18
A water fit up tool comprising:
- two bars for fitting on opposite sides of a water wall made up of a plurality of tubes welded between adjacent tubes, at least one of said two bars having a curved portion tangentially contacting the tubes and curving in a direction opposite to a curvature of the tubes for contacting two tubes therebetween, and
- a bolt passing through said two bars for moving the two bars closer together for drawing opposed ends of the tubes into vertical and axial alignment for subsequent welding of the opposed ends.
A water wall fit up tool comprising:
- two bars for fitting on opposite sides of a water wall made up of a plurality of tubes welded between adjacent tubes, and
- a bolt passing through said two bars for moving the two bars closer together for drawing opposed ends of the tubes into vertical and axial alignment for subsequent welding of the opposed ends,
- at least one of the two bars including three portions, a first one of the three portions having a first radius, a second one of the three portions having a second radius greater than the first radius and a third one of the three portions interconnecting the first portion and the second portion.
A water wall fit up tool comprising:
- two bars for fitting on opposite sides of a water wall made up of a plurality of tubes welded between adjacent tubes, and
- a bolt passing through said two bars for moving the two bars closer together for drawing opposed ends of the tubes into vertical and axial alignment for subsequent welding of the opposed ends,
- at least one of the two bars including a tether connected to a magnet.
A water wall assembly comprising:
- a plurality of tubes interconnected by welds, opposed ends of the tubes being spaced from the welds interconnecting the tubes, and
- two bars located on opposite sides of the tubes and bridging a gap between the opposed ends of the tubes for moving the opposed ends into vertical and axial alignment, at least one of said two bars having a curved portion tangentially contacting the tubes and curving in a direction opposite to a curvature of the tubes for contacting two tubes therebetween.
