Causes and corrective measures
Trouble
Groove width is too narrow or
too wide.
The groove zigzags.
The groove is not parallel with
the surface of the pipe end
Groove diameter is different
around the whole circumference
of the pipe
The pipe en flare (bell mouth) is
too large
The pipe slips out of the spindle
during grooving
The pipe slips during operation
and rotation is not smooth
Possible Causes
• The roller set differs from the
pipe size
• The pipe has been cut at an
angle
• The pipe is elliptical.
• Grooving speed is too fast.
• The roller set differs from the
pipe size
• The pipe shift angle is too large
• The pipe support is too high
• The grooving speed is too high
• The pipe shift direction is
opposite to the pipe threading
machine rotating direction.
• The pipe is too straight on the
spindle or the angle of the shift
is too small
• The pipe stand is too low.
• Spindle knurl is clogged or
worn out
• The grooving speed is too high

Corrective measures
• Replace the roller set with one
matching with the pipe size
• Cut the pipe at right angles
• Use a circular pipe
• Grooving at a slightly lower
speed is required
• Replace the roller set with one
matching the pipe size
• Adjust the pipe shift angle to
0.5 degrees
• Adjust the pipe support height
so that the pipe is 2 degrees
lower than the horizontal
position
• Grooving at a slightly lower
speed is required
• Shift the pipe in the correct
direction according to the pipe
threading machine rotating
direction
• Make the shift angle a little
larger
• Adjust the pipe support height
so that the pipe is 2 degrees
lower than the horizontal
position.
• Eliminate spindle knurl
clogging with a wire brush or
the like or replace the spindle
• Grooving at a slightly lower
speed is required
