Combination beading tools, 2.0", 2.1/2" and 3.0"OD.
More and more companies are
getting away from the the old way of
beading boiler tubes with pneumatic
hammers. The old process involved
rolling and flaring the ends.
Beading with a pneumatic
hammer which has left many an old
boilermaker deaf for the rest of his
life. then re-rolling the tube to
tighten it up after beading.
Using the Combination Beading Expander could not be more simple. From setting the projection from the sheet according to the gauge (wall thickness) the process is one easy operation. Insert the tool and roll and bead complete with no going back to re-roll.
As you can see from above all the rolls are consistent and uniform. These were 2.1/2" OD tubes and as you are rolling and beading at the same time you need a rolling motor rated for at least 3.0"OD. On the beading tool the beading roller is captured by a retainer plate which in some boilers foul the corresponding tube bead. This can be rectified by chamfering the edge of this plate with no detrimental effect on the operation of the tool.
