4.4 Cast Iron Pipe Joints
Locating the pipe first will make joint location
easier and faster. Because of its high metal
content, cast iron pipe can be located with a
Mag Horn but it is more efficient to use a
Pipehorn Pipe and Cable Locator to trace and
mark out the pipe location.
Set the Mag Horn sensitivity to maximum, fully
clockwise, and position the Mag Horn probe
tip approximately 1 foot above the ground over
the pipeline you have marked.
Do not sweep, turn or tilt the Mag Horn.
Keep it upright and positioned over the pipeline
marks as you walk the line.
Mark the point(s) where you experience peak
signals. Peak signals should occur at equal
distance, such as 20’ 0” for 20’ 0” sections of
pipe.
When you finish walking the line, go back and
check the marks you have made. Reduce
