Cutting concrete pipe
The procedure is dependent on the
outer diameter of the pipe, the maximum
possible cutting depth of the abrasive
wheel (A), and the possibility of rolling
the pipe during the cutting process.
Secure pipe against pinching,
N
vibrations, slipping and rolling away.
Note weight, tension and direction
N
of fall of the part to be severed.
Determine and mark direction of cut.
N
Determine sequence of cuts.
N
22
Outer diameter of pipe is smaller than
the maximum cutting depth
Make one cut from the top to the
N
bottom
Outer diameter of pipe is greater than
the maximum cutting depth
Plan first, then cut. Several cuts are
needed – correct sequence is important.
If the pipe is in-ground or otherwise
cannot be rolled:
To reduce the risk of pinching and
N
kickback, always start at the bottom,
use the front and upper part of the
abrasive wheel for cutting.
Use the front and upper part of the
N
abrasive wheel for cutting the
opposite lower side. Make sure that
the cut at the bottom is complete.
Next, make a first lateral cut on the
N
top half of the pipe, connecting with
the kerf from the bottom half.
A second lateral cut is then made in
N
the marked area. To keep the pipe
from pinching during this cut, never
cut into the area of the final cut.
