3.7 Cutting concrete pipe
A
The procedure is dependent on the outer diame‐
ter of the pipe and the maximum possible cutting
depth of the abrasive wheel (A).
► Secure pipe against vibrations, slipping and
rolling away
► Note weight, tension and direction of fall of the
part to be severed
► Determine and mark direction of cut
► Determine sequence of cuts
Outer diameter is smaller than the maximum cut‐
ting depth
► Make one cut from the top to the bottom
Outer diameter is greater than the maximum cut‐
ting depth
Plan first, then cut. Several cuts are needed –
correct sequence is important.
