In cold flanging one-, two- or three-phase flanging can be used. Multi-phase flanging is
used especially with small pipe dimensions and thin-walled pipes. Selection of the multi-
phase forming process can be done with a flanging mode select switch.
Multi-phase flanging means that the forming cone does not accomplish the forming
motion to the end but returns to the beginning once or twice. This return motion presses
away the fold, which reduces the flow area of the pipe.
14. Press the CYCLE START button
and machine carries out the flanging cycle.
The spindle stops automatically in correct position. If not, rotate it to correct position by
pressing the drum rotation push button
.
(Press the drum rotation push button briefly until drum is positioned to limit.)
If the spindle doesn’t revolve smoothly or if it stops, interrupt the work cycle
immediately by pressing EMERGENCY STOP).
Measure the flange, make necessary corrections and then enter to the setting value
table.
6.6 COLD FLANGING AND FLARING OF THE PIPE

5. Loosen the flanged pipe, inspect its measures and if unsatisfactory, make the necessary
corrections in the set values.
